Section B — Assertion & Reason

Question 9

A: The testes are housed in the scrotum outside the abdominal cavity.
R: Spermatogenesis needs a temperature a few degrees below normal body temperature.

Solution: The cooler scrotal temperature requirement is why the testes are external — R explains A.

Question 10

A: Human oogenesis produces only one functional ovum per primary oocyte.
R: The unequal meiotic divisions form polar bodies that degenerate.

Solution: Unequal division into polar bodies is why only one ovum forms — R explains A.

Question 11

A: The corpus luteum secretes large amounts of FSH.
R: The corpus luteum maintains the endometrium during the luteal phase.

Solution: A is false — the corpus luteum secretes progesterone, not FSH; R is true (it maintains the endometrium).

Question 12

A: Childbirth involves a positive feedback mechanism.
R: Uterine contractions stimulate more oxytocin release, which further intensifies the contractions.

Solution: Contractions → more oxytocin → stronger contractions is the positive feedback — R explains A.
