[0:00]Toh agar tumhe Biology me 360 on 360 ensure karna hai toh har prakar ka sawal karna aana chahiye. This is the handpicked NEET, only for serious aspirants jo level up karna chahte hain. NEET 2025 se bhi khatarnak paper aaye, usko bhi chutki baja ke niptaana chahte hain. Shuru karte hain. Session ka rule bahut simple sa hai. Main yahan par is wali video mein tumhare liye 15 sawal lekar ke aaya hoon. Tumhe sawal ko padhna hai, video ko pause karke khud solve karna hai. Phir agar answer sahi ho gaya ya galat ho gaya, dono hi case mein tumhe explanation ek baar sunna zaroor hai. Mera motto hai tumhara approach develop ho, dimag khule ki koi bhi sawal aaye tum dhang se usko nipta pao. Shuru karte hain. Iski playlist ka link already description mein hai. Teen videos aur bhi available hai tum ja karke usko zaroor dekhna description mein link hai. Pehla sawal aaj ka. Pause karo, padh lo, samajh lo phir hum discuss karte hain. Sawal kya kah raha hai, kar liya solve? Matlab try kar lo aaram se samay le lo apna. Let me now quickly explain you. Mujhse keh raha hai nucleus of an egg cell, the amount of DNA is 25 pg, matlab simple bhasha mein jo mera G, G keh raha hoon main, jo mera Meiosis 2 ka daughter cell hai, uske paas 25 pg ka content hai. Ab mujhe pata hona chahiye ki mera Meiosis 2 ka daughter cell ke paas jo bhi content hoga uska double content mera G1 ke upar hoga. Iska matlab G1 ke upar kitna, 50 pg content hai. Iska matlab jab tum G1 se G2 mein jaoge toh ye content double ho jayega toh 50 ka kitna ho jayega 100 pg. So correct answer is kitna? 100 pg. Sahi hua galat hua, koi baat nahin. Sikhna zaroori hai. Hai na? So this is the approach to solve. Agle sawal par chalte hain. Padh lo pause kar lo. Mujhse pooch raha hai, in mein se kaun sa DNA melting at the lowest temperature? Tum apna samay le lena main explanation continue rakhta hoon theek hai toh tum pause-vauz kar lena. Ab agar mujhe lowest temperature pe khojna hai toh lowest temperature ka kya logic hona chahiye? Logic ye hona chahiye ki GC ka matlab teen Hydrogen bond hai, AT ka matlab do Hydrogen bond hai. Jitna zyada GC ka content hoga, utna zyada bonding hogi, utna zyada melting point hogi. Toh lowest temperature matlab jiske paas sabse kam GC hai wo mera lowest MP dega. Toh main yahan GC content ginta hoon ek, do, toh yahan do hai, yahan ek, do, teen, char yahan char hai, yahan ek, do, teen yahan teen hai, yahan ek, do, teen, char hai. Toh sabse kam GC content kiske paas hai? Pehle wale ke paas toh logic samajh mein aaya? Simple sa funda yaad rakho. More GC, more stability, more melting point. Hai na? Less GC, lesser melting point hai na dhyan rakhna is cheez ko. So isi logic ke saath correct answer ho jayega option one. Achha, niyam bahut simple sa hai. Sahi ho raha ho, galat ho raha ho, aakhir tak bane rehna hai. Video khatam hone ke baad apne score ko comments mein daalna hai. Tabhi sikhoge. Matlab normal aisa mat karna ki khola, dekha, do question nahi bana, chalo chalte hain. Bhai kuch nahin hoga phir tumse. Tum aakhir tak sunna dhyan se. Aage agla sawal. Iske aaj mere paas variety hai, theek hai. Physiology ke bhi bade bade questions hain. Abhi shuru mein thoda ek do main aise rakhta hoon ki khali achha bachcha ruke. Sawal kya hai dhyan, pause karke apna padh-vadh lo, main samjhata hoon. Sawal keh raha hai ki homozygous for AB gene has 20 feet, while the minimum height is 6 feet. Yaani capital A capital A, capital B capital B is of 20 feet. Minimum height is 6 feet yaani small A small A, small B small B kitna hai? 6 feet hai. Ab main kya keh raha hoon ki inka each contribution nikalo. Jab char dominant hai toh 20 feet ka hai. Zero dominant hai toh 6 feet hai. Difference kitna hua mera? 14 feet. Yahan kitna dominant, zero dominant, yahan kitna dominant, char dominant, toh main 14/4 kar leta hoon. Kitna ho gaya ye? 2 * 2 = 4, 7, 3.5 ho gaya. Ye kya nikla? Ye nikla mera contribution of each dominant allele. Ab mujhe iski height nikalni hai. Kaise nikaloonga? Minimum likho sabse pehle. Minimum hai 6 feet, plus iske paas kitne dominant hain? Small A small A capital B small B ke paas ek toh 1 multiplied by ab dekho ek dominant ke aane se 3.5 feet height badhti hai toh into 3.5 kiya toh kitna ho gaya 9.5 feet, that is your correct answer. Sahi hua toh achhi baat hai, nahi hua toh iska na poora detailed concept explanation again genetics hacks mein milega. Ek bachcha main comment padh raha tha, kehta hai, "Sir aap genetics ke zyada questions." Main wo question laata hoon jisse bachcha bhagta hai. Main tumhe bhagne nahin doonga sawalon se, tumko nipatana sikhaoonga. Aage badhte hain agle sawal ke upar. Pedigree tumhare samne. Myotonic dystrophy hai autosomal dominant disorder hai. Affected children ka genotype kya hoga? Take a pause, soch lo. Kaise karna hai ab isko decode karte hain, dekho. Mere samne agar ye edit trait hai toh jo bhi non-affected hai usko small A small A kar do. Jitna aata hai pehle utna karna chahiye tumko. Kaam bahut asaan ho jata hai. Ab dhyan se dekhna agar ye mummy iski affected hai, agar main isko capital A capital A likhta tab toh mera kaam nahin banta, kyunki capital A capital A ka cross small A small A se karunga saare affected mil jayenge toh ye cancel karna pad gaya mujhe. Dhyan se dekhna toh main likhoonga capital A small A. Ye bachcha bhi mera capital A small A, ye bhi capital A small A, ye bhi capital A small A. Toh jitne bhi affected children honge woh kya honge? Capital A small A. See, affected individuals for an autosomal dominant trait can be capital A capital A or capital A small A. But in this very case, they are all kya? Capital A small A. Badhte hain agle sawal par.
[5:15]Achha, aise regular updates, regular classes bhi main le raha hoon, free classes. This is The Darwin Series full syllabus paper, roz sham ko 6:15 par hota hai. Mere Telegram par connect ho jao, description mein link hai. All details of this there, hai na? Matlab isme roz ke 100 questions practice kara raha hoon. You should be getting it done. Agla sawal. Sawal keh raha hai in a popu, tum apna pause karke kar lena. In a population frequency of recessive phenotype is 1% then what will be frequency of dominant allele? Bahut easy hai. Bana? Try karo, try karo. Pause kar lo aaram se. Kaise karenge? Recessive phenotype diya hai yaani ki q square is equal to 1% yaani 1/100, implies q is equal to 1/10 that is equal to 0.1. Ab mujhe pata hai P + Q = 1, toh P kitna ho gaya? 0.9. That is my answer, khatam kahani. Zyada sochna nahin hai yaar, kyun soch rahe ho bina matlab ka? That's it, final answer. Theek hai. Agla dekhte hain. Agla kya mujhse keh raha hai? Agla hai, pause karke tum apna solve karo main explain karta hoon. In a family husband and wife both have an X-linked dominant disorder. Then what will be the probability of normal son in children, if mother-in-law of husband was normal? Ab ek kaam karte hain isko thoda sa dimag lagate hain ek dum se. Toh mere samne kya condition hai dekho, family husband and wife both have an X-linked dominant disorder. Toh husband toh by default let's say X^a Y maine kar diya. Ab wife ki do possibility hain ya toh X^a X^a hoga ya toh X^a X hoga. Ye kaise identify karoge? Toh mujhse ye sawal keh raha hai ki mother-in-law, yaani ki is ladki ki mummy jo hai wo normal thi. Hai na? Toh agar is ladki ki mummy normal thi, iska matlab she must be kaisa type? She must be X^a X type individual. Agar hum ye cross karte hain toh kya milega dekho, X^a X^a milega, X^a X milega, phir kya milega? X^a Y milega, aur X Y milega. Ab mujhse keh raha hai, what will be the probability of normal son in children? Ab agar mujhe normal son ki probability nikalni hai toh yahan par dekho ye do sons dikhai de rahe hain. Normal son kitna ho gaya mere paas? Nipat gaya answer.
[7:27]Ab isme dekho bachcha na, chalo tumko main ek point add karta hoon. Main is sawal ki na do language de raha hoon. What is the probability to have a son which is normal?
[7:48]Aur dusra poochh raha hoon, to have a normal son. Kya in dono cases mein answer same hoga ki different hoga? Comments mein jab tum apna score daloge toh mujhe ye alag se batana. I have just bifurcated this question into two parts. I want answer for both the cases, theek hai? To have a son which is normal or to have a normal son, kya dono case mein answer same hai ki alag alag? Dimag lagana, answer dalna. Toh aate hain agle sawal ki taraf. Agla sawal mujhse keh raha hai ki during course of evolution, which of the following characters appeared first in phylum-annelida? Ab agar main phylum-annelida ki baat karta hoon toh bahut zyada dhyan se sunna aur samajhna. Bilateral symmetry toh pehle aa chuki hai. Tum apna pause karke solve karo, main toh samjha raha hoon. Toh bilateral symmetry hata denge, apna platyhelminthes se aa chuki hai. Toh apan option A eliminate kar diye. Phir mesodermal layer bhi triploblast jab se hue tab se aa chuka toh ye bhi eliminate kar do. Toh ye answer aa gaya. Kabhi kabhi zyada dimag nahin lagate bina matlab ka. Sahi sahi answer laga ke elimination se bhi kaam ho jata hai. Let's see what is the correct answer. Option third. Agla keh raha hai, not an unambiguous codon. Ab not an unambiguous codon ki agar main baat yahan par karta hoon toh dhyan se samajhna, apan padhte hain na AUG that is your start codon. Sath hi sath jo ye out of NCERT hai but dhyan rakhna is cheez ko kabhi kabhi out of NCERT molecular se aa chuke hain question, theek hai? Toh ab agar main GUG ki baat karta hoon toh GUG ki jo condition hai, ye normally valine ke liye code karta hai lekin jab ye start codon ki tarah behave karega tab ye methionine ke liye code matlab formyl methionine hota hai but utna bhi jaane ki zarurat nahin hai. Toh correct answer will be option one that is GUG. Agla sawal. The basic unit of natural selection is species, individual, population, genus. Toh jo basic unit of natural selection ki agar main baat yahan par karunga, toh dekho agar main evolution pe jata toh book ki koi line hai ki natural selection at it is at the population level natural selection operates, but jo isme right approach hoga na ki nature selects the fittest individual. Toh natural selection operates at individual level is line ke sath nikal karke tum chale jaoge. Agla hai. Pause kar lo. Dimag laga lo. Try karte hain. Mujhse keh raha hai correct for amount of DNA in different stages of meiosis if amount of DNA in G1 phase is 64 pg? Agar G1 mein mere paas 64 pg hai toh samajhna dhyan se, mera jo G2 hoga usmein 128 pg hoga aur yahi poore meiosis 1 mein continue hoga. Samajh mein aa rahi hai ye baat? Toh anaphase 1 128 is correct. Metaphase 1 128 is correct. Ab meiosis 1 ke daughter cell mein phir se 64 pg ho jayega aur yahi poore meiosis 2 mein chalega aur baad mein ja kar ke uska bhi aadha ho jayega yaani 32 pg ho jayega. Aayi kya baat samajh mein? Toh metaphase 2 64 is correct. Agla dekhte hain isme koi galti toh nahin hai? G2 mein 128 ye galat hai na? 256 nahin jayega. It won't be 256, 128 hi continue karna hai tumko hai na? Double continue karoge. Agla isme bhi ye bhi galat ho gaya aur iske baad ye bhi galat ho gaya. Toh correct answer dekhte hain option one. Sahi hua galat hua koi baat nahin. Agar is sawal mein problem hai toh cells ko draw karo. The mass at G1 is doubled at G2, right? Aur G2 pe jo mass hai wahi poore meiosis 1 mein continue karoge. Meiosis 2 ka daughter kitna ho jayega? 64 pg. Wahi 64 continue hoga meiosis 2 mein. Phir meiosis 2 ka daughter ho jayega 32. That's the approach. Theek hai? Agla dekhte hain. Ye toh easy hai. Aise hi solve ho jayega. Plasmodium gametocytes kahan banta hai? Batao. Kuch bachche na fat se tukka marenge gut of mosquito, sir. Ya salivary gland, dono galat hai. Gametocyte ka formation hota hai RBCs of human mein tumhe pata hona chahiye. These gametocytes get into the female Anopheles mosquito aur wahan jaane ke baad further aage hum discuss karte hain iska. Theek hai? Aage agla kya hai? Take a pause. Try karo. Chemiosmotic hypothesis ke hisaab se ATP synthase from ATP when protons kya? Toh protons nikalte hain thylakoid lumen se stroma ki taraf, so they move from thylakoid lumen to stroma by facilitated diffusion. Active nahin boloonga kyunki facilitated isliye bol raha hoon kyunki mujhe channel chahiye, along the gradient hi flow chal raha hai. Hai na? Toh facilitated diffusion ke sath nikal ke jayenge that is my correct answer. Agla mujhse keh rahe hain dekho, ectoparasite dekhte hi jawab aa jana chahiye. Take a pause, think. Kaun si machhli hai? All cyclostomies are ectoparasites on large fishes. Ye hai apna gole moo wali machhli, option one. Comments mein in baaki sabhi machhliyon ke mujhe naam batana. Kya tum photo dekh ke identify kar pa rahe ho ki nahin? Agla sawal. Take a pause. Think. Soch liya? Matlab tum apna pause karke socho, main batata hoon. Rhythm center hormonal nahin, neural control. Theek hai. Respiratory rhythm center medulla region, pneumotaxic pons region. Respiratory rhythm center can moderate pneu ulta likha hai. Role of oxygen is quite insignificant, toh teen galat hain. Apne ko kya poochha hai? In mein se kaun se incorrect hain? Correct answer is option third that is three are incorrect. Aakhri sawal. With reference to factors affecting the rate of photosynthesis, which of the following statements is not correct? Toh current availability of CO2 is sahi hai na C3 ke liye limiting hota hai kitna? Usko chahiye 450, available hai 400. Toh ye toh sahi hai. C3 respond to higher temperature with galat hai bhai. C4 respond to higher temperature aur isi ke sath aaj ke 15 set jo 15 questions ka set hai, samapt hota hai. Comments mein apna score dalna aur video ko like kar dena, dosto ko share kar dena. Sabko ye challenge do ki lo bhai tumse banta hai ki nahin banta hai. Telegram par connect kar lo. Main daily full syllabus mocks kara raha hoon sham ko 6:15 par. Stay connected here.
