• A. a-v, b-ii, c-iv, d-i, e-iii
• B. a-i, b-iii, c-ii, d-v, e-iv
• C. a-iii, b-ii, c-v, d-iv, e-i
• D. a-i, b-ii, c-iii, d-iv, e-v
• E. a-iv, b-ii, c-v, d-iii, e-i

Answer 1

Answer: (B)

a-i, b-iii, c-ii, d-v, e-iv

Hyaluronidase is an enzyme which is present in the acrosome of the sperm to degrade the hyluron present in the extracellular matrix of the ovum thus it is an acrosomal reaction.

The Corpus luteum is responsible for the secretion of progesterone which is important to maintain the endometrium lining during pregnancy.

Gastrulation is referred to as a process in which the cells of the blastula undergoes morphogenetic movements to form 3 germ layers and as a result, the next stage is gastrula.

Capacitation means the activation of the sperm so that it attains functional maturation and thus can induce fertilization.

Colostrum is the first milk produced by the mammary glands after birth. It is highly nutritive in nature and is rich in antibodies. It is yellow in colour and of a thick consistency.

So, the correct option is 'a-i, b-iii, c-ii, d-v, e-iv'
