  NEET Zoology PYQ (Inspired) – Set 1 | Human Physiology and Body Functions These 10 NEET-level Zoology questions are inspired by previous NEET papers (2016–2024), rewritten uniquely while keeping the same NCERT concepts and difficulty pattern. 1. Which part of the nephron is primarily responsible for selective reabsorption of glucose? Loop of Henle Distal convoluted tubule Collecting duct Proximal convoluted tubule (PCT) Check Answer Correct Answer: Proximal convoluted tubule PCT has abundant microvilli and mitochondria, enabling active reabsorption of glucose, amino acids, and ions. 2. Which one of the following hormones increases calcium absorption from the small intestine? Calcitonin Parathyroid hormone Thyroxine Insulin Check Answer Correct Answer: Parathyroid hormone PTH stimulates activation of Vitamin D, which enhances Ca 2+ absorption from the intestine. 3. Normal blood pressure in humans is approximately: 90/60 mm Hg ...

  NEET Chemistry  – Set 4 (Inorganic Chemistry) This set contains high-yield NCERT-based inorganic questions from s-block , p-block , d-block , and Coordination Compounds . Answers reveal on button click. Explanations are bilingual (English + Hinglish) for better understanding. Q31. Which of the following has the maximum ionic character ? LiF KF NaF CsF Check Answer Correct Answer: CsF Explanation: Ionic character ∝ (difference in electronegativity). As size ↑ down the group, cation becomes more electropositive → CsF is most ionic. Hinglish: Size bada → electron dene ki tendency zyada → ionic nature zyada. Q32. The oxidation state of Mn in KMnO₄ is: +5 +6 +7 +8 Check Answer Correct Answer: +7 Using MathJax: \[ \text{Let } x + (-2)\times4 + 1 = 0 \Rightarrow x = +7 \] Hinglish: KMnO₄ mein Mn ka oxidation state +7 hota hai — NCERT line. Q33. The colour of [Ti(H₂O)₆]³⁺ is due to: d–d transition Charge-tran...

Which reagent converts an alcohol to corresponding alkyl chloride most efficiently (without rearrangement)? (Organic synthesis) SOCl₂ (with pyridine) HCl (dilute) PCl₅ (hot) NaCl (aq) Check / Show solution Answer — (a) SOCl₂ (with pyridine) English: Thionyl chloride (SOCl₂) with pyridine converts alcohols to alkyl chlorides via an S_N2-like pathway with minimal rearrangement and gives gaseous by-products (SO₂, HCl) that escape—clean reaction. Hinglish: SOCl₂ + pyridine se alcohol → alkyl chloride achchhi tarah bina rearrangem...

 Q. Given below are two statements: Statement I: Atoms are electrically neutral as they contain equal number of positive and negative charges. Statement II: Atoms of each element are stable and emit their characteristic spectrum. In the light of the above statements, choose the most appropriate answer from the options given below.                                                          (NEET-2024) 1. Both Statement I and Statement II are correct 2. Both Statement I and Statement II are incorrect 3. Statement I is correct but Statement II is incorrect 4. Statement I is incorrect but Statement II is correct Show Answer   Answer (3) Sol. Statement I is true as atoms are electrically neutral because they contain equal number of positive and negative charges. Statement II is wrong as atom of most of the elements are stable and emi...

 Q. Two bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity v1 while body B is at rest before collision. The velocity of the system after collision is v2. The ratio v1:v2 is                                                         (NEET-2024) 1. 1 : 2  2. 2 : 1 3. 4 : 1  4. 1 : 4 Show Answer Before collision  It undergoes completely inelastic collision Using conservation of linear momentum Initial momentum = Final momentum => mv1 = mv2 + mv2 => mv1 = 2mv2 V1/v2 = 2/1
