(A) In human beings, menstrual cycle ceases around 50 years of age; this is termed as (i) .
(B) The milk produced during the initial few days of lactation is called (i) which contains several (ii) absolutely essential to develop resistance for the new-born babies.
(C) At the completion of the (i) division the primary oocyte divides into secondary oocyte and (ii) .

• A. (A)-(i) menarche; (B)-(i) lactation, (ii) minerals
• B. (B)-(i) colostrum, (ii) antibodies, (C)-(i) first meiotic, (ii) first polar body
• C. (A)-(i) menopause; (C)-(i) second meiotic, (ii) second polar body
• D. (A)-(i) menopause; (B)-(i) corpus luteum, (ii) antibodies

Answer 1

The correct option is B (B)-(i) colostrum, (ii) antibodies, (C)-(i) first meiotic, (ii) first polar body

The mammary glands of the female undergo differentiation after the pregnancy and starts producing milk towards the end of it, called lactation and the milk produced during these initial few days is referred to as colostrum. This contains many antibodies that is essential for the new born babies to develop resistance against any pathogen attack or disease. During oogenesis the gamete mother cell undergoes meiosis division to form the primary oocyte and this further divides into the secondary oocyte and a polar body by means of an unequal division.

So, the correct option is ' (B)-(i) colostrum, (ii) antibodies, (C)-(i) first meiotic, (ii) first polar body'.
