The Final 40 Questions Before RE-NEET 2026 | Biology

[00:00:00]Friend, let me come straight to the point.

[00:00:02]Till date, there has not been a single year where the ditto questions prepared by me did not come and there has not been a single year when bumper results with top ranks were not obtained. So Reed 2026 what's the big deal, man? Let us get the Top 40 questions done and dusted. Let's begin also I have already posted the top 50 questions here.

[00:00:18]I posted this video yesterday. So please ensure that you also complete it.

[00:00:22]Also, if the algorithm has delivered this video to you in time. So this is a guess paper. Also do two guess papers one and two. The paper is tomorrow. Don't take too much load. Do n't fall into FOMO. This is a must do, do it.

[00:00:33]50 + 40 questions. Let us begin with this now.

[00:00:35]Also, many people will start with enthusiasm but not everyone will reach the end. Also I don't want you guys to calculate this course today.

[00:00:42]Just go through it. Just learn from every question. Write down your answers somewhere. Don't get stressed out. Let's chill and listen. Let's keep listening. Let's keep listening. You have your paper tomorrow. Let us begin with this now.

[00:00:51]Everything like PDF etc. will be available on my WhatsApp channel. There is a link in the description. Pin the link in the comments.

[00:00:56]First question: Take a pause and give it a try. Iddip pidi question. How will you do it sir? Look and listen carefully. Who of ours got separated? In this the sisters got separated. If sister chromatids separate then metaphase cannot occur. Metaphase cannot occur.

[00:01:09]In anaphase one, homologs separate. What will be the answer? End. Pidi question. Next, you should know this by heart.

[00:01:16]Through which technology is the hepatitis B vaccine made? And in which organism is it produced? So technology is not my PCR. rRNA is not tech and the organism is not my E. coli.

[00:01:25]End. It was a good thing if I knew. If you do n't know, please recall. Don't be afraid, face it. Do 40 questions thoroughly and run away.

[00:01:33]After that relax. Also today on this YouTube channel this is the last video for practice and all before REET 2026. So I want a feedback. You must have been connected to this channel for a long time. Maybe you can give me some feedback in the comments.

[00:01:48]Ok? Let's move on to the next question.

[00:01:50]Chromosome in which centromere is present in almost at the middle. So if you are saying almost at the middle, that means make two equal arms. Who are you talking about?

[00:01:59]Speaking of metacentric chromosomes.

[00:02:01]Remember one more thing in this. There is a PY Q. Like after metacentric will come submeta, acro, tilo. Short arm and long arm will be filled in this. I have an arm formed by a pair of arms. PR is my short arm. QR is my long arm. Take care. Ok? Next Which property of acquired immunity is the basis of the concept of vaccination? It is a free question but still yes again it is a question of expectations.

[00:02:22]Tell me what will happen? Think about it. Look, vaccination is a technique in which I want to artificially immunize the body. How? I will give the undigested pathogen to the body or I will give the antigen.

[00:02:33]I will give you any of these two. The body will respond with active immunity. So this is a case of artificially acquired active immunity.

[00:02:38]Also, if the body does not remember the fights then this type of immunity is meaningless. So the point here is that the memory of the immune system is the core point that you have to remember. what is next? He is asking me the correct sequence of layers from inside to outside in a ruptured ovum. Friend, the raita may spread. Remember?

[00:02:56]What will be the first layer to come? Peribital space. Then the Zona Pacida. Then the corona radiata. This is the order. Because the space that comes to me above the egg membrane and between the zona pescida, that is the peribitional space. Then ZP then corona radiate. One more thing, zona pellucida is an acellular layer and corona radiata is a cellular layer, remember this also, zona pellucida prevents ectopic pregnancy. After keeping this in mind, the next question is asked how many of the above are secondary lymphoid organs, so you must have read only two names in primary lymphoid organ, one name which comes to me is thymus, one name which comes to me is bone marrow, so blow away one and five, option second that is your correct answer next.

[00:03:40]Take a pause and try.

[00:03:43]Choosing different times for feeding and different aging patterns can avoid competition. Meaning, in which case can you prevent competition by going to get food at different times.

[00:03:54]Closely related species do not have different habitats. Then the fight is when the habitat is the same.

[00:04:01]This story is true when there is a fight for the same resources. Similar niche sharing same habitat. Then this is correct and two species do not have different niches, see the functional role of niche is a simple concept, if suppose there is a tiger and a cheetah, both of them are living in the same habitat, then I can avoid competition between them by changing their foraging pattern and feeding pattern, right?

[00:04:23]But if suppose a tiger lives in this forest and what to say, a lion is 200 km away, then it does not make any sense, so your correct answer will be B and C, that is option second, let's say C and that is your final answer. Next, what is the next protonema?

[00:04:36]Meaning again a very famous question. It is not in Pteridophyta. There is something like a prothallus there.

[00:04:41]This is a cupping grasping green branch frequently filament stage. And that is what you are suppose to mark the question. Don't forget to remember. The next is the carboxylation of RuBP and decarboxylation of C4 acid in a Hachon-like pathway.

[00:05:02]Think about it. Hatchens like pathway means C4 pathway.

[00:05:05]So my first carboxylation that happens in the mesophyll cell is done by my papcase and it forms oxaloacetic acid.

[00:05:11]Then asking me about carboxylation of RuBP. Now where do I have this RUBP present?

[00:05:16]I have this presented in the cell below.

[00:05:18]I am talking about bundle sheet sale. So now this carboxylation of RuBP will happen in the bundle sheet cell. Next decarboxylation of C4 acid.

[00:05:25]Decarboxylation of C4 acid means that the oxalo acetic acid that I formed was converted into malic acid. It was transported and decarboxylated to form pyruvic acid. So this decarboxylation also happens in my bundle sheet cell. Correct answer will go to option four and moving ahead. The next type of placentation is the placenta that forms along the ventral surface. It stuck in a way. Isn't it?

[00:05:47]You must have seen such a pea seed. So here it is made for two days. That is the marginal line of NCERT. Have to be careful. Next, in which of these cases will the phenotype be affected? Think about it. Come, let me give you a job.

[00:06:01]This is a direct line of NCERT. This line is there in NCERT where incomplete dominance is discussed.

[00:06:08]Now see when the modified allele produces a normal enzyme. So if the modified one produces a normal enzyme, the unmodified one is also doing the same. So in this the phenotype may not be affected. Ok? So if this is not there then this is also not there. Now which of these two will you plant? I am leaving this to you separately.

[00:06:25]I am not even showing you the answer. Please tell me separately by putting the time stamp of the comment whether both are correct?

[00:06:30]You will sit down and open the NCERT line and NCERT writes in which cases it may be affected? Verify that line and tell whether both are correct or one is correct.

[00:06:37]Tell me separately before leaving. The next match I have in front of me is The Following. The first one is telling me bicuspid valve which is your type present? Bicuspid valve and then again outic semilan. This is very simple, friend. Let's see. Well, what is your strategy? We, you and I, are experts in this. Let's solve this through options.

[00:06:53]Ok? Let's see. Look if I dealt with look here 4 4 ​​2 3 let's do one thing. Let's try in B.

[00:07:00]Outic semilunar valve must be between left ventricle and outa. I have to do four of B.

[00:07:06]So if I do four of B, this is eliminated and this is eliminated.

[00:07:10]Next I have the pulmonary acinar valve. Where will it be presented? If you match D then the answer will come. I should not have a space present between the atrium and the ventricle.

[00:07:18]This should be present between the right ventricle and the pulmonary artery.

[00:07:22]So D's got three. And that is your final answer option second. You will approach it through option elimination only. Again, there is a match called The Following. We will go to our option.

[00:07:30]Let's see, see. 2 3 4 Are you getting any benefit from doing this match? Absolutely getting it. Two will be eliminated. Let's see, match B a little bit. The hinge joint is my knee joint.

[00:07:39]So I have to do two of B by default.

[00:07:41]So this elimination has happened.

[00:07:43]Sometimes if your luck is very good then it can be done directly through single matching. Let's move ahead. Who disappeared where? Super famous questions. You can't afford to skip this. This has to be learnt by rote only. If you have n't memorized it then dissolve it and drink it.

[00:07:56]Meaning, memorize it right now. Ok? Will you get the correct answer? Your option second that is dodo will go away Moresius.

[00:08:04]After that the quagga will be gone. Have to remember.

[00:08:06]No logic here. Ok? Whatever happened, happened.

[00:08:08]Rust Smut Puff Ball. Remember? Puxonia uslago smut fungus. You must have heard about rust fungus.

[00:08:14]Who do all these belong to? All of these belong to one fungal group. These are some of the most repeated PYQs. Those who understand the meaning, the child makes it silly and forgets. I am getting it recalled once.

[00:08:25]What are we talking about?

[00:08:27]Basidiomycetes. The next mild question is this silly mistake question. Mild uterine contractions at the time of parturition.

[00:08:34]What will happen? R because of oxytocin.

[00:08:37]This is the reflex of a fully dull placenta only as the level of estrogen decreases. What will you plant? See these mild contractions is written by NCERT. This is called your fetal ejection reflex, we know it by the name of this. And this will lead to oxytocin, then more contractions, then more oxytocin, then more contractions, and it keeps increasing. There is a positive feedback loop.

[00:08:59]Options will go with seconds. Next you will see this NCERT diagram of B.

[00:09:03]How will you approach him like this, sir? Option elimination. A is my plumule.

[00:09:07]Eliminate Eliminate Eliminate is over.

[00:09:11]Whom will we see after that? Let's look at B. B is the quotation. Is the question done, sir? Some kids do this. Sir, A. This must be B. It's a good thing, traditional society is doing this, but you stay away. When you reach this video, you are with me. I have smart kids here. Okay, so approach smartly. You have to say, in a competitive exam, it's not a display of knowledge, it's a strategic display.

[00:09:34]Come on, the next match is the following super famous questions. Today I have brought the super famous ones. So, if I talk about butyric acid, what will you apply? I made a mistake, I did n't see the option. No, now I will have to apply deutericum. If you talk about D, then eliminate it. Eliminate it.

[00:09:50]What else do you have to do, sir? You won't even read C. C is the same in both. After this, if you talk about cyclosporine, A. If you talk about statins, will the marking be lost? You have to remember it.

[00:09:59]Ultimately, Acetobacter aceti of acetic acid is gone. And the rest, you have a simple factual question.

[00:10:04]Remember this. If it is there then it is good, otherwise please open it and drink it, there is no new logic in it, next glucagon stimulates various metabolic functions, except one glucagon is a hyperglycemic and hypoglycemic, apply common sense. See gluconeogenesis making new glucose from non-carbohydrate sources raises my blood sugar. Isn't it? So this would be the cause of hyperglycemia is glycolysis hyperglycemia. Even if you leave out the odd one, it still becomes your question.

[00:10:33]Glycogenesis will produce glycogen. Blood sugar will decrease. Next, you have to memorize this and along with this question, I would also like to tell you that if you have not memorized the table of secondary metabolites, then definitely turn that page once before sleeping tonight. That is the purpose of these papers to make you aware.

[00:10:55]Ahead. The next one I have in front of me is Choose the Wrong Option. Ok? Was playing in a fig fruit is an example of mutual. That is absolutely true. A is my true. I want the wrong option. Is my question done? I blew these two away. Let's see more. This Mycorrhiza Act is wrong.

[00:11:12]B should be a part of an answer. Both have B. Now look, do you know what I'm going to think of next? I'll next look at my C statement, Physiological Ecology is Ecology at the Organismic Level. A line of NCERT again. So I have true with C.

[00:11:25]But the D one is 100% wrong. It was not corner. Cones had an elegant field experiment. Gauss's Competitive Exclusion Principle. So the correct answer will be option third that is B and D are incorrect. The next one is in front of you. It is shown below and that is autosomal dominant given. Find out the genotype of the individual for number three, four and five respectively.

[00:11:49]How will you approach? Look, if it is autosomal dominant then by default all the normal small a's will be all small a's.

[00:12:01]Now you have given me this number so that I can have it. This one number can be capital A, capital A and capital A, small A anything. I don't care about a number.

[00:12:11]But it will be confirmed that number three should be capital A, small A or else these children will not be able to be born. So capital A, small A of number three is any option. It got eliminated. And let's see, he has asked me four also. Now if you look at number four, then number four again can be only one thing capital A small A because this affected individual is coming in front of me here.

[00:12:30]So number four also capital A small eliminated.

[00:12:33]Well, my answer has come. Still, I'll go for number five for you.

[00:12:36]Here's number five, by default it can be capital LA. Correct answer is option one.

[00:12:41]That is capital A capital A, capital A. Next question to me is this graph given in front of me. He is asking me if in this energy level of product wood has been higher than the energy level of substrate, that is, this is the level of substrate, then this is the level of product than which of the following wood has been, correct? So understand what happens here.

[00:13:00]If I have a substrate level that goes above the product level. Meaning if energy is absorbed then the reaction becomes endothermic. Many children answer by giving blank graphs. Don't do that. You have to see the entire question once, otherwise the mess will spread. So it has become endothermic. We will eliminate Eggo. We will eliminate Eggo. Now only Endo Endo is left.

[00:13:17]Ok? So both of them got eliminated. Now he is asking me what is the situation? So the one A I have is with enzyme and the one B is without. Option third will be your correct answer. next. How many sphericals are there in a cockroach? No logic here. Just a fact. Sir, there are 10 pairs. 10 pairs, many people will bet 10. Tell me separately if you are making a mistake.

[00:13:38]How much will the correct answer be? B. Because I have 10 pairs.

[00:13:40]Next one is near me, that is, near the cockroach. Next, I have to figure out which of these is the correct reference with respect to the frog. The first is that the eyes have come from outside. That's correct.

[00:13:48]Nicking membrane is absolutely true. The membranous tympanum is true. Never drinks water is true. Nostrils above the mouth. This is also true. All these given statements are fine. All are lines of NCERT. Didn't know. Please do a one shot video of frog on this channel once.

[00:14:03]Expect questions from Frog. Ok?

[00:14:05]Next Which of the following is a wrong statement with respect to gas exchange in plants?

[00:14:10]Read carefully. Each plant part takes care of its own gas exchange needs. That is true. Plants Do Not Present Great Demand for Gas. That is also. Do you know where it is written? At the very beginning of the Respiration chapter.

[00:14:22]Transport of gas from one plant part to another. There is minimal transport, not sufficient. I will keep this in mind as well. Option third is your correct answer. This is a discussion about why plants do not have any lungs and let's say gills and anything as such.

[00:14:37]Ok? Next thing I have is that the metabolic breakdown of carbohydrates, fatty acids, amino acids all at one point if you want to bring that single molecule is my acetyl coenzyme A. Just remember that.

[00:14:48]Next chromatophore. C. Mesosomes take part in respiration. Chromatophores are pigment-containing membranous extensions that are going to take part in one thing. And that is my what? Photosynthesis. Next, methionine, tryptophan, terpenoids are the producers of phytohormones like gases.

[00:15:04]Terpenoids, Monoterpenes, Diterpenes It's about Gibberellic Acid. I will be eliminating this. Then tryptophan in the presence of Zn+ is for on? I will be eliminating this and I have my answer.

[00:15:15]Do it by elimination. Time will be saved and this is what you have to do. I am making you develop an understanding approach. Next How many radial spokes and microtubules in the axoneme of eukaryotic cilia flagella. Now look, it has become simple. That's why there are nine radial spokes. I know myself. Two options flew away. Now sir, how many microtubules are there? You write 9 + 2 arrangement. Out of these, these nine are doublets. These two are singletons.

[00:15:41]Now these nine doublets are written as 9 * 2 + 2 * 1.

[00:15:44]How much is it? What is 18 + 2? It's 20. End of story. So what is the number of microtubules? It is 20. And what is the number of radial spokes? It is nine. The matter ends here. So that is your correct answer. next. Which of the following is a correct match? Check this out. Mustard is not like that. Onion Liliaceae 3 + 3 is the perfect order. Second is absolutely fine.

[00:16:10]Tell me in the comment section. What is the problem here? I want to know the problem here. Ok? What is the problem here?

[00:16:15]Tell me in the comment section. Plus peas do n't have this kind of char. If you talk about peas, then the condition of 1 + 2 + two fused comes.

[00:16:24]Third, tell me what is the mistake? I want to know in the comments. Next heterospory is found in. Look heterospory is something that evolved very later on that is was not in thallophyta. Not present in Bryophyta.

[00:16:34]Some pteridophytes had its heterospory in pterido.

[00:16:37]Then all Gymnosperma all Angiosperma had heterospory. So what comes here is that some members of Pteridophyta all members of Spermatophyta that is seed producing plants. That is Spermatophyta. Gymnosperma. Sperm is coming, right? Sperma means seed. Phyta means plant. Next, which one of these, yikes, yikes, yikes, yikes, I mean, I am saying yikes, it is my habit, he wants to know from you about such abnormally folded proteins, that is prions, CJD, you must have heard about mad disease, you must have heard about prions, let's talk about prions, keep this in mind, next, remember all this also brother, what is a viroid, sir, he said, sir, RNA of low molecular weight without protein, what is a prion, sir, prions are just proteinaceous particles, sir, TO Diner 1971 Potato Spindle Tuber Disease, it must be sitting in the mind of the solution. Which of the following statements is correct in the context of observing DNA fragments? Will not be visible in visible light. Will not be visible without staining. Will not be visible in visible light. Stain it evenly and then look at it in UV light, only then it will be visible.

[00:17:37]Too many repeated P/Q. If you are on BAMA One site, keep pausing and trying.

[00:17:45]What happens if you ligate foreign DNA at the BamA1 site?

[00:17:48]Remember the site Sir BAMA One Sir Bansal drinks juice in tetra pack so the sites of BAMA One Salvan are on TTR sites.

[00:17:55]So if I insert foreign DNA here, my BamA one resistance, sorry tetracycline resistance, is lost. So it won't be showing tetracycline resistance. Ah it won't grow on tetracycline. It will just show amicillin resistance. And that is my correct answer. what is next? Meristem culture. I will give you a task here.

[00:18:15]You must have read in meristem culture that just pick any apical axillary meristem and culture it, you will get a virus free plant.

[00:18:21]Tell me in the comment section with this time stamp, brother, which are the plants that are made through this technique? Moving ahead to next NPV Nucleopolyhedrovirus You must have heard about Bakkilo virus. This is an incorrect question. Species specific is true. Narrowspectrum is true. Negative impact on no, this is absolutely wrong. They do not have any negative. That is why they are preferred in ecologically sensitive areas. Next, if someone has 10 multiple alleles, then how many types of homozygous conditions are possible? Someone from Common Sense Lets had two ellils. T How homozygous? T Suppose there is someone a b c how much will it be? A would be A, BB would be CC. Are you able to understand my feeling that how many types of homozygous conditions are possible. So now you can pick only one set at a time, which means maximum two alleles will come at a time and homozygous can be formed like this, so if you have 10 multiple alleles then 10 homozygous conditions are possible, that's it, what is next, in [ __ ] blood grouping, how many alleles, how many genotypes, how many phenotypes, if you remember very well then I AB IO these are three alleles, I A I B I I I O, after this I B I B I B I O, then I O I O, 1 2 3 4 5 6 there are six genotypes and four phenotypes. So the correct answer will be that there are three alleles and six genotypes.

[00:19:48]Which four? A, A, B, B and O. So the correct answer will be your third option. The next very beautiful question is placed before you here in center fuse. It is written that light DNA molecules were replicated in heavy medium. That means my parent was my light. Which means if I made Parental, it would be my top one because it would be the lightest. So my first point is that I will blow away the lightest segment because parental copies are never repeated. Now I got it divided four times and when I got the incells divided four times, I got 16 DNA. Now see what will happen, a simple story. The parent must have been N14, N14. What did you get when you divided it for the first time? N14, N15, N14, N15 then divided, what did you get? N14, N15, N14, N15, N15, N15, N15, N15 because medium is my N15.

[00:20:39]Now you see two bands will be formed. One heavy band, one medium band. So my concept of three bands is wrong. Well, there shouldn't be that much gap. This became my heaviest band of 15 each. This became my band of hybrids. Third is my correct answer. Ok? These questions are linked with NCERT Matches and Stars Experiment.

[00:20:56]next. Choose the correct combination of sex determination in males respectfully. C The male partner Whichever partner is heterozygous it decides is X of the child. So if I am talking about Chidiya it is ZW type. So it's not ZW for sure, it's not XX for sure. It is not x va for sure. This question is done by a single matching. Grasshopper was a question from NEET 2026.

[00:21:19]X in type humans and X in type honey bee became haploid. Let us move forward. A female is a carrier for both albinism and color blindness. Let's just write it down. So what do I write? Capital LA, this is female and here I have written x C X for color blindness. She gets married to a man who has albinism and the poor guy is color blind. Ok? Cross of xcy When you perform this cross, see what you get. I am making empty girls because the question here is interested in daughters. Ok? Look, if you cross xc with xcy, you can get xc or you can get x xc.

[00:21:56]Ok? Now if you cross these two then capital A capital A capital A capital A small A small A now what kind of child do you want here how many of the daughters can be albino now what is the chance of being albino this is only one chance it is an autosomal recessive trait so it is written 1/4 what is the chance of being color blind sir 1 2 1/2 is color blind so 1/2 * 1 sorry my bad 1/2 * 1/4 you will have to take out the product how much will it come 1/8 now how will you do it sir 1/8 is there now convert 1/8 into percentage what is it? If you do 1/4 then you will get 25 and half of 25 is 12.5%, that is your correct answer. Option third. What did you do? Did you understand? If this doesn't come then skip it now.

[00:22:38]Don't take the load a day before the exam. If it comes, I will get it recalled once.

[00:22:42]Well, this is explained in detail in the video of Genetics Hacks. You can check it in Genetics Hacks. If you want, you have time so don't stress. Ok? So I did this math.

[00:22:50]Well, you guys are looking at the math, if my math was wrong. Meaning, 1/8 is just that. Let's move ahead.

[00:22:55]Finish finish finish. Set finished. This evening will be the last session for NEET 2026 students.

[00:23:01]It's an open invitation to all of you. See you later at 6 pm today and we will talk about everything about what things you need to take special care of tomorrow so that you do not do anything rash or rash. Let's get it done and dusted. We have worked very hard for Renate. Brother, come and have a great day. Be sure to write a few things about your journey in the comments. Ok? I will be reading all of them. And take no stress. A calm mind does phenomenal results. Remember this. If you take too much load, the work will be spoiled. Ok? I believe in you. Always remember that. Ok? So let's crack it. Go give your best.

[00:23:35]Don't take too much pressure on anything. How will it be?

[00:23:37]What will happen? We will see brother. I am here too, you. I always say I am there for you. Ok? So now we will meet in this session and after this we will directly go into analysis. Let's crack it. If you are new here subscribe, like, share, hype. Hype it up today. Today is the day before NEET. Competition will not increase today. Go hype it right now. Let's crack it.
