1. Q1.Botany · Sexual reproduction in flowering plants · Fresh

   Assertion (A): In an anther whose tapetum degenerates very early, the microspore mother cells do not give rise to normal viable pollen grains, although the epidermis, endothecium and middle layers of the anther wall are intact.
   Reason (R): The tapetum nourishes the developing pollen grains.
   In the light of the above statements, choose the correct answer from the options given below.

   1. (1)Both (A) and (R) are true and (R) is the correct explanation of (A)
   2. (2)Both (A) and (R) are true but (R) is not the correct explanation of (A)
   3. (3)(A) is true but (R) is false
   4. (4)(A) is false but (R) is true

   Answer (1)

   Of the four wall layers of the microsporangium, only the innermost – the tapetum – nourishes the developing pollen grains; the other three protect the anther and help it dehisce.

   If the tapetum fails early, the microspores get no nourishment, so viable pollen is not formed. (R) is true and explains (A).

2. Q2.Zoology · Body fluids and circulation · Fresh

   Consider the following statements about the heart and circulation in vertebrates.
   (a) Fishes have a 2-chambered heart that pumps only deoxygenated blood, which is oxygenated in the gills (single circulation).
   (b) Amphibians have a 3-chambered heart with two atria and a single ventricle, in which oxygenated and deoxygenated blood get mixed.
   (c) Crocodiles, like all other reptiles, have a 3-chambered heart.
   (d) Birds and mammals have a 4-chambered heart with complete double circulation.
   (e) In fishes, the heart receives oxygenated blood from the gills and pumps it to the body.
   Choose the correct answer from the options given below:

   1. (1)(a), (b), (c) and (d)
   2. (2)(b), (c) and (e) only
   3. (3)(a), (d) and (e) only
   4. (4)(a), (b) and (d) only

   Answer (4)

   (a), (b) and (d) are correct.

   (c) is wrong – crocodiles are the exception among reptiles, with a 4-chambered heart. (e) is wrong – the fish heart pumps only deoxygenated blood; blood from the gills goes straight to the body.

3. Q3.Chemistry · Biomolecules · Fresh

   Read the following statements about glucose:
   (a) Glucose reacts with hydroxylamine to form an oxime.
   (b) Glucose gives a pink colour with Schiff’s reagent.
   (c) Glucose is oxidised by bromine water to gluconic acid.
   (d) Prolonged heating of glucose with HI gives n-hexane.
   (e) Glucose pentaacetate does not react with hydroxylamine.
   (f) Glucose forms the crystalline addition product with sodium hydrogen sulphite (NaHSO₃).
   How many of the above statements are correct?

   1. (1)1
   2. (2)2
   3. (3)3
   4. (4)4

   Answer (4)

   Correct: (a) oxime with NH₂OH, (c) gluconic acid with bromine water, (d) n-hexane with HI, (e) the pentaacetate does not react with NH₂OH.

   Wrong: (b) and (f) – glucose does not give Schiff’s test or the NaHSO₃ addition product, because it exists mostly in the cyclic form. So 4 statements are correct.

4. Q4.Zoology · Neural control and coordination · Fresh

   Which one of the following statements about non-myelinated nerve fibres is correct?

   1. (1)They are enclosed by a Schwann cell that forms a myelin sheath with gaps called nodes of Ranvier, and are commonly found in the autonomic and the somatic neural systems
   2. (2)They are enclosed by a Schwann cell that does not form a myelin sheath around the axon, and are commonly found in the autonomic and the somatic neural systems
   3. (3)They have no Schwann cell covering at all and are commonly found in spinal and cranial nerves
   4. (4)They are enclosed by a Schwann cell that does not form a myelin sheath around the axon, and are mostly found in spinal and cranial nerves

   Answer (2)

   NCERT line: a non-myelinated fibre is enclosed by a Schwann cell that does not form a myelin sheath, and such fibres are commonly found in the autonomic and the somatic neural systems.

   Option (4) gives the place of myelinated fibres (spinal and cranial nerves); option (1) describes a myelinated fibre.

5. Q5.Botany · Molecular basis of inheritance · NEET PYQ · 2021

   Which one of the following statements about Histones is wrong?

   1. (1)Histones carry positive charge in the side chain
   2. (2)Histones are organized to form a unit of 8 molecules
   3. (3)The pH of histones is slightly acidic
   4. (4)Histones are rich in amino acids - Lysine and Arginine

   Answer (3)

   Histones are basic proteins, rich in lysine and arginine, with positively charged side chains; eight of them form the histone octamer.

   So “the pH of histones is slightly acidic” is the wrong statement.

Statement questions, Assertion–Reason and “how many are correct” – straight from the NCERT lines.
