Added: 2026-06-02

[00:00:28]Put it up Afternoon. Good afternoon everyone.

[00:00:34]Good evening. In fact, it's evening time.

[00:00:44]We are here for human and social biology. Uh there is a exam tomorrow that we are all looking forward to.

[00:01:03]I hope everyone is well prepared. Were you able to watch uh the various videos we have done to help you prepare?

[00:01:13]There's a whole playlist in fact.

[00:01:16]So I hope everyone was able to um check out the videos for that playlist.

[00:01:22]They're quite a few of them. So person should be uh prepared or feel that they have been prepared sufficiently and I hope so I hope you were able to get to check out some of those videos.

[00:01:40]Yeah, I really hope you were able to get them.

[00:01:53]If you were not able to then uh then this live session will definitely help you out.

[00:02:02]This live session will definitely help you out. Uh your principal everyone knows you wouldn't be hardened. Um so yeah just want to do some a last set of practice. Some of you may need it. Some of you may say, "Oh, I feel confident going in." So, just giving persons the opportunity to put in that little extra effort. That may be the difference between you getting a one instead of a two. Yeah. So, we want to use the um June 2024 paper, the June 2024 paper one. Well, paper one and paper three is tomorrow as well.

[00:02:51]Um so not throwing that out. I hope persons were also also prepared for the for the paper um the paper tree. Yeah.

[00:03:06]I hope I very much hope that you are.

[00:03:11]Yeah. So just giving persons the opportunity to sign to join in the chat.

[00:03:17]Um, and you all can tell me where you all are doing these papers from. Which territory are you in?

[00:03:25]Which territory are you in?

[00:03:28]Do let me know. Do let me know.

[00:03:38]Do let me know which territory you are in.

[00:03:46]If you are doing this, this shouldn't take us. So if we take a little bit, this should be under on under hour. So let's about get ready to kick things off.

[00:04:20]All right. So, I think that is enough time waited for persons. Hi. I'm seeing some Jamaicans, Gy. Yes, I watched the entire playlist as you should, right? That makes sense that you should watch the entire playlist. They're quite a few. And one of the patterns coming out and why we're using the 2024 um paper is that we are seeing that the it's two years apart. So if we are in 2026 it means it's a very there are very many questions that should come from the 2024 paper. So it's two years apart.

[00:05:03]That's why persons would and and some of you would have seen it too well. So the pattern from the 2025 was from the 2023 paper. Yeah. So we are in 2026. Good to have other trees in the room as well. So we in 2026. So tonight I'm just going to look through the 2024 paper just to give you uh some practice.

[00:05:30]Uh ideally you are supposed to take a minute or accounting for reading time you want to take about a minute and 10 seconds that's the maximum you are supposed to spend on a question a minute and 10 seconds right that means 70 70 seconds but I know persons especially those who have watched the playlist who would be rolling through the questions a lot faster than that. Yeah.

[00:06:05]Yeah. So, we're getting ready. Uh let me just set up things on my end and open up the paper and we'll be able to to roll right along. So, let's go. Let's go. Let's go.

[00:06:28]Yeah.

[00:06:33]Okay.

[00:06:39]All right. All right. So, and do make sure you subscribe to the channel. We use the subscribes as just a way of encouragement to show, hey, yeah, people are using the material we are producing to help them get their ones in their exams. All right. So we are jumping into uh this uh let me share this try to shift it over a little bit.

[00:07:20]All right. So all right. Yeah. Yeah. It's yeah and there are just a few more days of exams at the CC level it's finishing what on the it's in the the 9th or not this Tuesday next week Tuesday right so it's not that far again uh that much more exams again so let's get into it this is the this is the June 2024 and we are starting off with question one someone is already telling us the answer. Um uh item one refers to the following aquatic food chain and we know that the questions come in the order of the syllabus. Good night. Good night to all of you. The question comes in the order of the syllabus. So section A, section B and section B is broken up into nutrition, respiration following along ending with reproduction. Section C which is the genetics, section D the diseases and section E to end off the 60 questions.

[00:08:28]Right? So question one this food chain phytolanton eaten by zup plankton eaten by fish eaten by bird. The producer in this food chain is the first one. The phytolanton is the producer. So you're just looking for the I know everyone said the in the chat already. Um yeah and I know there's chemone is talking about they're ready for chem.

[00:08:53]Um there is chem tomorrow or they're saying they're not ready for chem. There is chem in the afternoon along with music. Right. So four exams. Um question two. Which of the following features is not common to all living things? And that not is in capital letters. You have to look out for those capitalized words.

[00:09:15]Right. Use food to produce energy.

[00:09:18]Producing identical um cells in reproduction. Getting rid of metabolic waste products. Releasing energy by the process of respiration. So which one of these is not common? Uh what are we saying chat? Are you are you saying be like me? And I'm seeing some some of you already saying B. So be placing identical cells in reproduction that is not a requirement that is not a requirement of life or living things.

[00:09:54]Question three and four refer to the following diagram in which osmosis is demonstrated and you notice I'm delaying because I'm giving you chance to put your answer before mine. The main function of the viscin tube is to act as a right. So we know this is a osmosis and many of you might have done this in the lab. Yeah. And the definition of osmosis is um the movement of water particles through a semi-p permeable membrane. So you're looking for something that says that the answer is D. Yeah. For question three, the answer is D.

[00:10:40]Um, question four, which of the following processes occurs after several hours? And if you just look at the concentration gradient, there's 20% sugar solution outside the viscan tube and on the inside there is sugar solution of 40%. So water is moving to go in the viscin tube. All right. So we just looking for one that says that water moves from the beaker into the viscin tube. And for question four, everybody should be choosing B. But I'm seeing persons saying for 2024.

[00:11:22]Right. Right. They're saying B. Right.

[00:11:24]I'm just I'm just wondering. All right.

[00:11:31]Question five.

[00:11:34]The site of photosynthesis in plants is had this had they put leaves in this question, it would have be so funny, right? But they put chloroplast stomata.

[00:11:49]Um the stomata you know the stomata is the paw. O know the stem and the roots right. So chloroplast chloroplast is obviously the best answer.

[00:12:03]Yeah the best answer. So for question five we are going with a. Yeah we are going with a. I hope I hope everyone is so far matching my answers.

[00:12:21]here and I hope everyone is matching the answers so far. Uh question six. So you see that we are finished with with with that first topic section A and now we are into the nutrition questions. So generally the first four or five questions is section A and now we are into section B which is nutrition. The first topic in section B is nutrition. the asks um this diagram of parts of the human digestive system.

[00:12:54]We know one is the liver, two is the stomach, three is the small intestines and they ask us which of the following correctly matches each numbered section to its function. The liver is the um production of bile. So we could just take one and we already see that it lines up with C. And I know the whole chat is going off with C which means the whole chat is correct. This is a very popular question. This is a very popular question.

[00:13:25]Once you see this question, remember me.

[00:13:29]Remember your favorite principal?

[00:13:30]Principal Roach and smile because this you you're getting a mark.

[00:13:36]Seven. Um which of the label parts contain blood vessels and nerves? Yeah, just take your time and watch where the the label line points to. Take your time and watch where the label line points to. CXC prints in black and white. Yeah, some persons can get uh how I should say a problematic paper. You could ask for a switch of paper. If you you find your copy is not very good, you could ask for a switch of paper. Don't be, you know, digital duplicators do make problems sometimes, right? You don't know if you got a best copy, if you not seen your label lines properly.

[00:14:20]Ask for another paper.

[00:14:23]Um, which of the following teeth aid in the grinding of food into smaller pieces? You know, all of us have chewed gum in our lives and chewed food in our lives and everyone is going looking for your back teeth. So the mers and preolars for uh number eight everyone is on B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B That's all I'm seeing in the chat.

[00:14:45]So it means everyone is okay. Yeah.

[00:14:48]Okay. So so far so good.

[00:14:51]B I say B for B. Yes. Uh question um nine. Please remember to walk with your ruler. I know, I know it's multiple choice. Just walk with your ruler.

[00:15:06]Just walk with your ruler. Which of the following foods is most likely a cereal?

[00:15:13]Which of the following foods is most likely a cereal? Remember cereals, all the corn flakes, the Frosted Flakes, the Froot Loops, the the Kelloggs, the Nestle, the Sunshine, the What brand of cereal it? Well, I don't know every brand in the world, right? But the cereals are plenty plenty for for sugar.

[00:15:34]They are plenty for sugar and they they often dry.

[00:15:38]Yeah, they often dry. So little water, plenty carbohydrates, sugar and some protein. They never have fat in them. So we know the answer is D. Let me just switch to writing. So we know the answer is D. Everyone know that. And number 10.

[00:15:54]Which of the following above is not suitable that capitalized word uh for a person suffering from arterioclerosis?

[00:16:03]uh for question 10 and you don't want the person who's suffering from arterial sclerosis eating more fat. So the fattiest one which is C is not suitable is not suitable.

[00:16:20]Yeah.

[00:16:31]Um, someone is asking we allow calculations for this paper. The calculations you supposed to be able to do in your head or on the paper. So, calculators for paper two. No, but you need a calculator for paper three. So, if you're going if you're doing paper three, you got to work with your calculator anyway.

[00:16:49]All right.

[00:16:51]Um, yeah, somebody um um Austin, you really confident with the answers, which is what I like. Yeah.

[00:17:01]C um C for number 10 11. During the process of digestion, bile salts aid in emulsification.

[00:17:11]Emulsification.

[00:17:13]That's what bile salts are.

[00:17:14]Emulsification is the breaking up of fat into lumps. Fat can accumulate and clump together. You want to take chunks of fat out of something, right? To break it up.

[00:17:28]You want to increase the surface area, the bile salts does that for you. That's the simplest way to describe it. It takes a lump of fat and you add salts to it, it emulsifies in that it forms little globules of fat to be broken down. All right, so that's emulsification.

[00:17:49]Um, question 12. Which of the following phrases best describes ejection?

[00:17:58]Best. So it means it could have more than one answer. It's the best. Removal of metabolic waste. No, it has to be non- metabolic waste. Removal of undigested food from the elementary canal. Yes. So 12. We are going with C.

[00:18:15]Right. Undigested food is non metabolic waste.

[00:18:25]Oh, someone said they got a two in 204.

[00:18:27]That's cool. That's awesome. And you came back to check us. Thanks for passing through um news. Thanks for passing through. Um which of the following for 13 uh is not a function of the colon. The colon you might know it as the large intestines.

[00:18:48]Right? There are three parts of the colon. the ascending colon, the transverse colon, the descending colon, but you just have to know it as the colon. Um, so question 13, uh, brief storage of undigested food. Uh, but take just take your time, read all the answers. Absorption of water into the body, absorption of mineral salts into the body, absorption of digested food material into the body. It's we're looking for the not the not um, for question 13.

[00:19:19]So the rectum is responsible. Um do we do social studies? Yeah, we do we do social studies.

[00:19:34]This somebody's asking what paper is this? This is 204.

[00:19:40]This is the May June 2024 paper one.

[00:19:44]Yeah.

[00:19:46]Right.

[00:19:51]Oh, he's studying to become a teacher of social sciences. Nice. That's awesome.

[00:19:56]That is awesome.

[00:19:59]Someone is saying 14 is C. Oh, tell us the answer for 14. Which of the following vitamins is water soluble? Um if you're thinking for 14 vitamin B and C are water soluble then yeah B is the correct answer totally awesome vitamin C. Yeah vitamin B and vitamin C are water soluble. Take your time with this question. They like to switch it between fat soluble and water soluble. Right. So changing that one word will give you a different answer. Just take your time with the question, right?

[00:20:49]Um which of the following represents the correct sequence of events in the formation of a dental cavity? Abs enamel decay, dentine decay, plaque formation.

[00:21:03]All right. So we know this all starts off with plaque formation and the plaque is on the outside of the tooth which harbors the bacteria to be able to break down the enamel. So after the plaque formation after four we going to two three and then one. So we're looking for that 4 2 3 1 which is C.

[00:21:24]Yeah. Which is C. Take your time with the answer. Um, take your time with the answers, right?

[00:21:36]Enamel is on the outside. Enamel is the is the the white that you see on your teeth. All right, so just take your time. Take your time. Which of the following substances found in cigarette smoke is addictive? And I think everyone should know this answer that it's nicotine. Nicotine is one of, if not the most addictive substance in the world.

[00:21:58]Yeah.

[00:22:00]So, just take your time with that. Take your time. Um, item 17 refers to the following graph.

[00:22:10]Which of the following can be deduced from the graph? And you just look at your graph and you see it's trending upwards, the number of cigarettes smoked per day. When it have plenty words for the question, the answers, the responses, you have to read all of them.

[00:22:26]Read them. read them through. And as the number of cigarettes smoked per day increases, the risk of getting lung cancer increases. And that is true.

[00:22:38]Yeah, I know plenty of you have done this question before, so you're able to easily recognize it, which is good.

[00:22:45]Which is good. So, you're very familiar, right? That's part of doing the examiner, being familiar with what they're asking. Being familiar with what with what is is being asked and the expectation of you that helps that helps you in getting that much closer to getting your what?

[00:23:09]Yeah.

[00:23:13]Oops.

[00:23:32]Did my stream?

[00:23:40]Why is it reconnected?

[00:23:57]All right. So, let's let's check this out.

[00:24:12]Question 18. Question 18.

[00:24:22]During a sprint, muscles in the human body produce lactic acid by a process of anorobic respiration. They already told you it was a sprint. They said it was intense activity.

[00:24:40]So it's anorobic respiration.

[00:24:51]Let me just check something out here.

[00:25:37]19. Let me just take a time to read the chat.

[00:25:45]Just Yeah. Um during somebody saying I'm Marie K West and they want the answers. Yeah, we're doing the answers right now. What? What do you mean you want the answers? We're doing the answers right now for you. So, don't be worried. And you all know that you all could just go on the on our website early.com and get all these papers, right? These we provide the pass, we have the papers free on the website, right? So, you all could just download them or anything from the website if you want. Um, question 19. During respiration, the release of energy in a cell occurs when ATP is converted to ADP. That's when you use energy. It's like using your phone.

[00:26:37]Um when you want to use the phone, you charge up the phone, which is in the ATP stage. And when you want to use it, meaning you want to use the energy, it's converted to the ADP stage. So yeah, a read my name.

[00:27:09]Right. Yes, they can mix up or change the order in which these answers are put. Right. They can't think they can put change the order. That's why we encourage you to read all of them. So, not just because you know it was A last time doesn't mean they can't move the same response to the B. They can't move it. So, just read it. Take your time.

[00:27:35]So, when would the answer be B? ADP ADP is converted to ATPs when you when the equation that equation the respiration equation you using food to generate energy you're not using the energy you're generating energy when it is B right um question 20 we mentioning capillaries which mean the next topic is circulation. Capillaries have very thin um walls which only have um one layer of cells. This is to allow rapid diffusion of gases and substances like glucose. Yeah. So 20 you're getting the answer as being B.

[00:28:37]Yeah.

[00:28:46]Um, question 21.

[00:28:50]High blood pressure most likely leads to high blood pressure most likely leads to cardiac problems, stomach ulcers, liver damage, lung damage. Well, considering high blood pressure is from the heart, you should be doing something with cardiac. So, a 21 is a Yeah.

[00:29:18]Um 22. Which of the following statements describe the lymphatic system in humans?

[00:29:25]It is part of the circulatory system or one of whose function is to transport fats. It is a cir it is a circulatory system consisting of tissue fluid, lymph and plasma. Yes, that is better than that than A. It is a very small it has a very small role to play in fighting off micro microorganisms. That's true but still not better than B. Um it consists of lymph and tissue flu its own. That is also true but the best answer which is what multiple choice is about. The best answer is B. So, we see that all of these answers are correct, but the best one is B. Yeah, the best one is B. So, if we had just picked the first one, we would have be in trouble, right? Which is why I'm telling you to get your one, read all your answers.

[00:30:19]Um, question 23.

[00:30:25]Red blood cells contain no nucleus because uh they have hemoglobin. It improves their oxygen carrying capacity. They are too small. No, they're not too small.

[00:30:37]Cells are microscopic. Uh right. Um B they do have hemoglobin. C they have icon gave this. That's true. But D is the best answer. It improves their oxygen carrying capacity. So 23 we are choosing D.

[00:30:57]24.

[00:31:00]Yeah, you all could let me know if you all have different answers or probably you want more explanation for one of the answers or if my answer is wrong and you think you have the right answer, do let me know in the comments. Yeah. And if you need a more explanation to understand how I got that answer, just ask me. I will I do look at the chat so I'll be able hopefully I'll be able to catch it. Um which of the following best describes the function of a pacemaker in the heart? And they ask for best increase the heart rate. Yes. Regulates the heart rate that is better than increase decrease the heart rate. Yes.

[00:31:45]But regulates is better. Prevents the heart from overworking. It's supposed to. But the best answer again is B. So we see there was last three questions all of them we have to choose the best response right because nearly all the response is correct right so 24 is B this word they could either use the word regulate or control those are the two words acceptable for this question regulate or control right someone is saying chemistry you doing the chemistry tomorrow afternoon That's nice. That's nice.

[00:32:24]Um, item 25 refers to the following diagram of a human arm.

[00:32:33]Um, when the arm is bent or flexed, what happens?

[00:32:44]When the arm is bent or flex, the tricep shortens. No, the tricep should lengthen. Um, but the bicep pulls on the radius. 25 is the there 25 is the 26.

[00:33:12]Which of the following joints allow movement in all directions?

[00:33:20]Which one allows movement in all directions?

[00:33:29]Is it a knee, ankle, elbow, shoulder?

[00:33:31]And if you get this question in the exam, you have all these joints. So when you see knee, everybody should be kicking their foot to see if the foot could move in all direction. When you see shoulder, everybody should be going, "Yeah, yeah, my shoulder moving all around." So everybody should know the answer or get to the answer when it comes to these questions. Yeah.

[00:33:51]27. Which refers to the following diagram? Part of the human skeleton.

[00:33:58]Which of the following combination correctly identifies bones labeled X, Y, and Z? X is the feur. We looking for that. We have the option between B and D. We looking for Y. And if you see Y points to the thick bone, the tibia and Z points to the fibula.

[00:34:22]Right? So we going with B.

[00:34:26]Yeah. And I just remember tidia as thick, fibia as flimsy.

[00:34:33]That's that's how I try to encourage students to learn it, you know, to try to find patterns so that the brain always remember it. So they're not mixing up which one is which one. Um and likewise for when you have if you have the um the the forearm.

[00:34:50]Yeah. You remember the word up ulna and pinky. So you know that the ulna runs in line with your pinky finger up. Up and pinky. So that makes sense.

[00:35:06]So obviously it's the radius and the thumb, right? So just things I try to help students with.

[00:35:16]Uh so we looking at some we looking at which one represents the pelvic girdle.

[00:35:22]This one is jumping out at us instantly.

[00:35:26]Yeah. B for 28.

[00:35:35]Uh B for 28.

[00:35:39]Let's go on to 29.

[00:35:42]If you want subscribe to the channel, please subscribe to the channel. Show your support for Early to CXC. Um your principal, Mr. approach just going through this uh June 2024 ask paper in preparation for tomorrow the 2026 May June paper one exam so let's continue with question number 29 some of you have already come up with your answer which of the following describes homeostasis homeostasis I know the chat is already telling me a yes it is the maintenance of the constant internal environment You want to keep that as level as possible. You want to keep that the same. You don't want any changes in your internal environment that leads to trouble. Yeah.

[00:36:35]Item 30 and 31 refer to the following simplified diagram of a kidney tubule.

[00:36:41]Answers uh for 31 may be used once, more than once or not at all. So question 13, which label part collects filtrate from the glomemelus? The glus is this network capillary inside here and it's going out into this area and you see B literally right there. The Bman's capsule. You see B is the labeling for right. So let me just write that in right there.

[00:37:14]B right the Bowman's capsule collects the filtrate form the glomemeilus and that's the only one that's labeled right there which label part brings blood to the glus that will be a thert arterial is slightly larger than the efferior right so we know and this is why I tell you walk with a ruler in the exam you can measure this and see that the difference is 1 millm or half of a millimeter Yeah, which is showing the difference in the side. The a is supposed to be a little bigger than the efron side. So you know which side is which and you know the direction. So it's the answer is a and everyone would have had their ruler to be able to measure. Hence I'm reminding you to walk with your ruler.

[00:38:12]um the following diagram of a human brain and they have some parts labeled out for you. Which part of the brain is responsible for conscious thought? When you want to study human and social biology, you need to use your cerebrum.

[00:38:29]Yeah. So 32 the answer is a.

[00:38:35]Yeah. you want to use your cerebrum and come tomorrow morning, everybody's cerebrum would be in play at about 9:00 to about 10:15 EST time. Everybody, your brains will be firing because your principal prepared you. Yeah, someone is already telling me the answer for 33 is D. Let's see if they are correct. Which of the following occurs when blood sugar level rises above normal? insulin should be secreted to help reduce the blood sugar level normal. It converts um glucose to glycogen and insulin secretion is increased. So yes, that person um so much comments coming already but I can't even find back when the person tell me but that person is correct. The central nervous system is made up of the brain and spinal cord. This is a giveaway. This is a giveaway question.

[00:39:34]Everybody should have that phrase memorized. Brain and spinal cord.

[00:39:38]Everything else is your peripheral nervous system.

[00:39:42]Yeah.

[00:39:44]Um, which of the following is an involuntary action? Is it eating? Is it walking? Is it breathing? Or riding a bike?

[00:40:02]You know, a student once um told me, he's like, "Sir, when I born, I was already eating. They didn't have to teach me to eat or anything. It's I know that by heart." And I was like, "You sure? Nobody didn't have to help you with with breastfeeding and you sure?" He's like, "Yes, sir. I know that. Nobody didn't have to help me, right?

[00:40:28]But I know that student was just making fun. But the answer for this question for 30 um 35 is C. Yeah, the answer is C.

[00:40:39]Um somebody saying please review question 19.

[00:40:45]What's happening question 19? What was question 19? What was question 19?

[00:40:54]Question 19. You're not understanding question 19. I could go it over. I could go it over for you and and probably I could do some some let me do some uh quick writing for you. So uh for question 19. So we have ATP ATP is in the adenosine triphosphate right we have the A which is the adenosine and it have phosphates attached to it. So we have one, we have two, we have three. All right, we have three phosphate groups. Hence it's a denosine triphosphate, right? Which is what ATP. This is how energy is stored.

[00:41:40]This is how energy is stored.

[00:41:43]When we want to release the energy, we have to break this bond. We have to mash up this bond to release the energy, right?

[00:41:56]And the question asks the release of the energy in the cell during respiration.

[00:42:02]The release of the energy in the cell.

[00:42:04]So we have to break this bond. When we break this bond, it means we are removing and let me just we are removing if we remove this this um this P here we end up with a PP which is diphosphate a denosine diphosphate two phosphates. So the answer is a I am explaining this for um um let me see who somebody just asked me that right um David David you just asked me this to review question 19 does that help you During respiration, the release of energy in cells occurs. Yes, this is it.

[00:43:05]This is energy being released, right, David?

[00:43:18]Somebody saying sir isn't that the result and not during. What do you mean by the result and not during?

[00:43:26]Respiration is the respiration is the ability to do work and the ability to do work has to you have to create the energy then you have to use it. This is how you use the energy that is created.

[00:43:45]The energy creation is the equation what that you know as glucose plus oxygen to create um water, carbon dioxide and ATP.

[00:43:56]This is the energy being created to be able to be used.

[00:44:04]Right? So this this is it. This is it.

[00:44:07]The release of energy in the cell occurs when ATP is converted. This is it.

[00:44:13]Right. So, I I I hope that helps.

[00:44:17]All right. I hope that helps. All right.

[00:44:19]Let's go back to where we were.

[00:44:26]Um I can't even remember where we were.

[00:44:32]Um we did all of that already, boy. 35.

[00:44:39]Right. Right. Yeah. So we were on 36.

[00:44:43]We won 36, right?

[00:44:49]But remember I told you all that question they can move the answer. They could move the answer from being a. So depending on which paper you're reading, just don't don't learn the letters if you if that's what you're doing. Learn the response.

[00:45:10]Right. So, but even my explanation, right? So, all right. Question 36 refers to the following diagram of the longitudinal section through a human eye. The part labeled X's and we have X right here. This is the this is the iris.

[00:45:29]This is the iris. This is the pupil space right here that lets light into the lens to hit the lens. So we know the iris and the iris is the colored part, right?

[00:45:50]All right. And we see we moving on to the final topic for section B. Um in question 37, ovulation is the process by which a female becomes pregnant. No, it's a mature egg is released into the ovid. Remember the reason why they have mature egg because the female has all the eggs she would have, right? And the start of the menstrual cycle, it also has eggs. The follicle developing, right? They need to be developed and once it's mature, it is released. All right? So ovulation is the release of a mature egg.

[00:46:36]All right. Okay. Good. Good.

[00:46:44]Um let's do this question. Question 38.

[00:46:50]Question 38 refers to the following diagram which shows light rays passing through the pupil.

[00:46:58]the image that is formed. And when we watch these light rays, look at the light rays. Look at them here. Look at them passing here. Right? We hit, we have a convex lens. So when the light hits it, it bends, right? When the light hits the lens, it bends. And the image, the image is the convergence point of the light, which is right here. You see where the it gets darkest? I mean I mean strip it's right the the oh jeez this convergence point is right here.

[00:47:51]Yeah.

[00:47:58]So, all right. So, the image is formed in front of the Well, it's formed long in front of the retina. All right. So, all right.

[00:48:16]You hope they don't bring much stuff about the eye.

[00:48:34]Somebody saying is broken down. Who's was was broken down?

[00:48:43]Do you start with 80?

[00:48:53]Right. So, um AJ AJ is back with his question 19. AJ really wants this point.

[00:49:00]AJ, so far you are correct. Um you use to store the energy you have to get another you have to add another phosphate bond to ATP to ADP. That's correct. And when it is broken when the a when the new bond which is ATP is broken it releases the energy. That is correct. And the question literally asks the release of energy.

[00:49:29]Right. So yeah. So our answer is correct. AJ I think I'm not too sure if you're supporting my point AJ.

[00:49:47]All right. So yeah. Um so quest um question 39.

[00:49:53]Someone is telling me the answer.

[00:49:56]Menration in the human female begins when ovulation starts. Estrogen levels are high. Progesterone levels are high.

[00:50:05]The uterine walls break down. We looking for something that indicates the period.

[00:50:11]Yeah. And the period we know it's the shedding of the uterine walls, right? So yes. Yes. Um 39 is the 39 is D.

[00:50:25]All right. Remember progesterone and estrogen levels will start to pick up.

[00:50:29]Those are ovarian hormones. So estrogen levels should pick up when ovulation is about to happen. and progesterone levels should pick up and then even get even higher when there is implantation.

[00:50:43]Yeah. So be mindful of those ovarian hormones.

[00:50:51]Someone is saying Right. All right. So, let's move on to to question 40.

[00:51:12]Which of the following correctly identifies the structures labeled one, two, three, and four?

[00:51:21]Right. One, two, three and four. Just go through them one by one. So start off with one, you know that is the sperm d.

[00:51:29]Start off with two, you know that is ureitra. And once you reach two, you already see that C is your answer for question 14.

[00:51:41]Right? Someone is saying guys just pick whatever you believe. No, you want to pick the right answer. We want to pick the right answer now. Whatever we believe, pick the right answer. Right.

[00:51:53]Um 41. Which of the following methods of female contraception functions by preventing sperm from entering the uterus? Yeah, that would have to be a barrier method. The barrier method which is a right. the barrier. Somebody saying they can't find the 2026 syllabus anywhere.

[00:52:21]Listen, all of this is on our website.

[00:52:24]You could just type in um what is this?

[00:52:27]Affected affected ali. You could just type in early to cexe.com and go and see all the syllabus there.

[00:52:40]Yeah. So you see sex subjects all the syllabus on the website. So just type in early to cexc.com.

[00:52:46]All right. Section and we see we moving into the genetics is question two. This means section C is here right.

[00:53:03]>> Um so we have DNA DNA replication and then we have two deployed cells.

[00:53:10]deployed his whole cells, right? So, we obviously already see that if it's two and it's deployed, we already see that this is mitosis. So, when they ask us the process illustrated above for question 42, we already know the answer is a mitosis. Glad to see everyone is there with me. No issues with this question. I guess this question is an easy question for everyone. Wonderful.

[00:53:36]Let's see how we faring with question um 40 43. The following genotypes are given for two parents both of whom can roll their tongues. We have father and mother. The father is hetererozygous.

[00:53:53]The mother is homozygous dominant. Which of the following genotypes is are not possible for any of their offspring? The one that is not possible is the homozygous recessive.

[00:54:08]So this one is not possible. We are looking for that. So it means for 43 the answer is C. And everyone else has arrived at that.

[00:54:20]Yes. Everybody. Yeah. I want all of you to pass. Everybody Everybody had to pass HSB, right? We aiming for 60 out of 60.

[00:54:31]Item 44 refers to the following genetic cross which shows the inheritance of blood groups in humans. Alles A and B are co-ominant to each other and both are dominant to O. This is usually how regular blood groups. So just follow they didn't do a ponet square with this but all you have to do is follow the lines. Which of the following offspring inherited the homozygous recessive? You know that is O. Just follow the lines and see where the O's go to. If you follow the lines, you run O to O. You see that it's coming out to N. Which one is N? D.

[00:55:10]Easy, right?

[00:55:14]You might get 50ome. No, you getting 60.

[00:55:20]Principal Roach. Not working so hard for you to get 50 something. 60, right? 60.

[00:55:29]Which of the following is an example of genetic engineering? Using stem cells to produce organs, tissue culting, banana production, cloning in high producing animals, produce production of insulin, E.coli bacteria. This is the only one in your syllabus that you are required to know. Production of insulin by E.coli bacteria. That's the answer.

[00:55:53]That's the answer. D the whole the whole chat is these right D.

[00:56:04]Um let's go to 46 refers to the following diagram of a mother breastfeeding her baby. What kind of immunity is illustrated by the activity above? This is question 46. If she's breastfeeding, it means she's giving the baby uh through colostrum and breastfeeding. She's giving the baby its immune response. She is natural.

[00:56:29]Breastfeeding is a natural thing and the baby's getting this passively. Meaning the baby's immune system is not doing anything. It's just receiving it. So, we looking for natural and passive, which makes the answer they glad that everyone else is also getting those answers.

[00:56:49]Yeah.

[00:56:53]Um, question, what is this? 47. Berry berry is an example of a disease that is classified as a deficiency, a nutritional deficiency. If you're not eating all your vitamin, if you're not eating all your vitamin B, you could end up with berry bed.

[00:57:14]Yeah.

[00:57:17]What's the difference between them for 46? Somebody's asking me what's the difference. So, let me explain out. Um, let me explain out 46. So, why does it keep moving? All right. 46.

[00:57:32]What's the difference? Naturally acquired. Active. Naturally acquired. uh but active is active and passive refers to the person's body the person's immune system having to put in effort. If it is active the person's immune system has to do work. It has to create the response.

[00:57:53]If it is passive it means the immune system is just given whatever it is right it's just given the immune response. natural and acquired.

[00:58:05]Um, natural and artificial means artificial means man-made. There's no secrets about that. Man-made. So, it's man doing it. And man-made means a man in a lab or something doing something, right? Natural means this is nature.

[00:58:23]This is how it's naturally happens.

[00:58:25]Yeah. So, that's it. So, you just it's four things and you just look for which one it is. So a mother and a baby is natural active. The baby's immune system is not doing anything. The baby's immune system is in lazy mode and it's just receiving the immune response from the mother.

[00:58:44]Hence we are going with passive natural acquired passive. Yeah, I hope that clears up the answer for you. Um there's always so much so much things pass right. Um reborn I hope that gives that clears up the answer for you. I did that explanation for you.

[00:59:11]Okay, let's look at this this mosquito life cycle. Which of the following stages is not found in or on water? We know mosquitoes as adults, they're flying around. They laying their eggs at the water's edge. The lava will hatch and go into the water. The people are also found in the water. And once they um cocoon and break out of the cocoon, they get their wings and they fly out of the water. Right. So two, three, and four are in the water. We are looking for um we are looking for that or something that says that which is the yeah which is what everyone in the chat was saying right somebody saying this is a throwway question why you boy dread take all the marks that you could get you find question too Is it you should be happy?

[01:00:18]You should be happy when you get easy questions.

[01:00:22]Right.

[01:00:25]Item uh 49 refers to the following information. It is caused by bacterium.

[01:00:32]Person practicing poor hygiene are more susceptible. It can be fatal without medical treatment. It involves the formation of ulcers. Which statement is true about cholera? And it just requires you to know that the first three things cola is a bacterium. Vibrioalora is the name of the bacterium. Practicing poor hygiene does make you more susceptible.

[01:00:56]It can be fatal. Yeah. And but it does not involve the formation of ulcers. So one two um for for one two and three for 49 which puts us for 49 the answer is C. All right. Someone asking how much papers we do. We wrapping up with this one. How much paper how much papers you want to do?

[01:01:25]Right. Yeah. I guess you weren't here at the start. Um Um Ghost, you weren't here at the start. Which of the following cells does the AIDS virus attack? What we thinking? we know it has to be one of the white blood cells. Uh so that puts the answer between fagosytes and lymphocytes and it attacks the tea cells which responsible for releasing antibodies or mounting an immune response. So we know it is lymphocytes.

[01:02:00]Yeah. So for 50 we are C faggoytes is a type of white blood cell urethraittes trombocytes is well ureitraittes is red blood cells trombocytes is the platelets they're just using the fancy words for them right they're just using the fancy words these mosquito is known for the spread of and I always tell students this is a easy question. This is a giveaway question. Anophles is only responsible for malaria. Alsi is responsible for everything else.

[01:02:41]So that makes it really easy. Just know anophles for malaria. Everything else is 80s egyptile.

[01:02:50]That's the easiest that's the easiest way to learn that.

[01:02:56]Um question um 52. Which of the following statements about herpes is true?

[01:03:05]Everyone is there. Somebody has already given the answer for 52. Yeah. The saying is see there is no known cure for the disease. As it stands this is what this is it right. We don't know if the the we don't know if the future will change will change it but as it stands there is no known cure for millise.

[01:03:31]Yeah. So and we know those questions are coming from the from the um section D of the syllabus. Yeah.

[01:03:41]So we are entering into um we are entering into section E water pollution may be controlled by Take your time just read the answers. as um fate faith this is the uh this is the June 2024 paper that we are doing yes these questions really a um repeat a lot yes and faith don't be faith there's a whole playlist that you could check out as well we have a whole playlist for all the different years and stuff um 53 tree water pollution may be controlled by what's our answer educating the public and implementing laws and you all know that the Caribbean has just entered this May into the rainy season. Yeah. So the rainy season just started a few days ago. So we all know that the different in the different territories the different ministries and stuff started taking action against mosquito the expected mosquito increases with respect to the population of mosquitoes. Yeah.

[01:05:14]Um question 54. Which of the following measures should an individual utilize to control diabetes? They should increase their carbohydrate intake.

[01:05:25]They surely should not, right? They should not increase the carbohydrate intake to to um control diabetes. That that will lead to trouble anyway. So they should adopt a heavy active lifestyle. Yes. They should lose weight.

[01:05:41]Yes. So two and three. So that makes 54 C. 54 C.

[01:05:49]Right.

[01:05:51]54 C.

[01:05:58]Um, which of the following substances contribute to the excessive growth of algae in waterways?

[01:06:10]And just remember fertilizers and what your fertilizers what your fertilizers are. The nitrates and the phosphates is the best for fertilizers. They think of that's why they tell you plant legumes because the legumes add nitrates to the soil. Yeah. So nitrates and the phosphates they are the best fertilizer.

[01:06:31]I'm not saying sulfates aren't a fertilizer for but for the best for growth phosphates and nitrates. Yeah. So as someone said BBB question 56 recycling may best be defined as what's recycling?

[01:06:52]What's recycling?

[01:06:56]Um yeah repossessing of collected resources into new products. So 56 is B.

[01:07:06]Is somebody saying it's blurry? This is blurry.

[01:07:14]Is it too big or something? Are you saying it's blurry?

[01:07:23]Uh 57.

[01:07:26]In the water in the water cycle, water vapor enters the atmosphere by by what? respiration from animals, transpiration from plants, precipitation from clouds. So if water entering the atmosphere, how is it precipitation from clouds?

[01:07:54]Right? So it's one and two.

[01:08:07]Right.

[01:08:12]Precipitation from clouds is actually water coming out of the atmosphere.

[01:08:17]Right?

[01:08:20]Um someone is saying precipitation.

[01:08:22]Precipitation is like rainfall or snowfall or hail, right? Those things are acts of precipitation. So that is not water entering the atmosphere. That is water coming out of the atmosphere.

[01:08:34]Transpiration is the loss of water from plants.

[01:08:38]So that goes upwards. Respiration, you know, in respiration, the reason why the the mirror fs up is when you breathe on the mirror, that's water vapor. So every time you breathe out, water vapor is going into the atmosphere. Yeah. So it's one and two.

[01:08:57]Um 58.

[01:09:02]Um 58. In large scale water purification, the formation of acid which destroys organisms is achieved by the process of chlorination. Yeah. And many of us would have gotten water in our pipes at homes and we see like little bubbles um bubbles in the water.

[01:09:21]Yeah, that's from the chlorine. You could let it settle. You could drink that as it is. It it does nothing to you, but you can let it settle and it will bubble out.

[01:09:33]So 58 the answer is C. Someone says 59 is boiling and chlorination. All right.

[01:09:41]Well, let's see. the most effective ways of purifying water in the home. Well, I guess the person was right, is boiling and chlorination, which makes the answer C. So, that person was right for 59.

[01:09:54]And our final question for this um June 2024 paper one is which of the following is an example of a nonbiodegradable pollutant?

[01:10:10]And it's a nonbiodegradable pollutant.

[01:10:13]They put it in bold letters because they didn't want you to mix it up. The answer is Oh, that didn't come out good. The answer is he. Yeah. So, this question was a. So that's our 60 questions for this um May 2026 paper 2024 paper.

[01:10:42]Yeah.

[01:10:46]How are we feeling? Are we feeling confident? Are we are we Yeah, we think we going and it look forward to many of these questions repeating. Please just take your time.

[01:11:00]Just take your time. And I have no doubt that you all will come back and say, "Hey sir, we should be looking at the one you know." And I will smile and say, "Yes, yes, yes." Yeah.

[01:11:14]Um, somebody saying, "Let's do 2025." And I and I even put out a 2025 paper um for you all to watch. I hope persons are watching. Please watch the playlist.

[01:11:29]Watch the playlist, please.

[01:11:33]Yeah, it's a whole playlist. There are something like there are over 10 multiple choice papers on the playlist for you to watch. Please watch them.

[01:11:42]Yeah.

[01:11:44]Um, yeah. So, you all are feeling good.

[01:11:48]Wonderful. Wonderful. So, I want to wish you all we we spent long. We spent the whole time that it will take to do a a a paper one hour and 15 minutes your 75 minutes. We talk the whole time. I made sure and give you explanations.

[01:12:03]Your favorite principle made sure and help you out. Just some of you are just making some slight mistakes because you are rushing. You will not be in a rush.

[01:12:13]Take your time. Read carefully. Walk with your rulers, please. Yeah. Some people are saying one more. You all want me to do another paper? You all don't have to sleep to prepare for tomorrow.

[01:12:26]Yeah. Right. So, all right. So, I am leaving you here. I prepared you. I'm confident that you all will do good. If anyone gets the paper tomorrow, please remember to send it send it to me. You could upload it on the website early.com or you could just um reach out, send it via the email, you could send it over to us. But your favorite principal want to wish you a wonderful paper one exam tomorrow. And for those of you who are doing paper three, enjoy your paper three that is 1 hour long. Um 14 questions. You will like the questions. It's a scenario where you are compiling a report.

[01:13:15]Yeah. The first two questions, the hypothesis and the aim, the problem statement comes from the information they give you. Yeah. So, you should be reading that over and highlighting the aim. Everything is in there. All right.

[01:13:32]So, I know you all will have fun with the HSV exams tomorrow. Those of you who have um chemistry and music as well, do have a wonderful exam. Anyone gets the paper, send it to me. We look forward to putting out our answers tomorrow night.

[01:13:49]All right. Good evening everyone. Good luck in your exams. Take care. Your favorite principal reminding you to subscribe and like the video. But otherwise, have an enjoyable evening.

[01:14:02]Bye-bye everyone. Take care class.
