Which statements regarding the effects of FSH and characteristics of Arachnida are correct? (Options are assumed to be C for Q31 and may vary for Q32)

Question 31:
The direct effects of Follicle-Stimulating Hormone (FSH) include:

• i. Development of the corpus luteum: This is primarily stimulated by Luteinizing Hormone (LH) after ovulation, not directly by FSH. (False)
• ii. Development of the Graafian follicle: FSH is essential for the growth and maturation of ovarian follicles, including the Graafian follicle, in females. (True)
• iii. Ovulation: Ovulation is triggered by a surge in LH, not directly by FSH. (False)
• iv. Stimulation of sperm production: In males, FSH stimulates spermatogenesis (sperm production) in the seminiferous tubules of the testes. (True)

Therefore, statements (ii) and (iv) are correct.
This corresponds to option C.

Question 32:
Members of the Class Arachnida differ from other Classes of Arthropods in that:

• i. They lack antennae: Arachnids (e.g., spiders, scorpions) do not possess antennae, unlike insects and crustaceans. (True)
• ii. They possess four pairs of walking legs: Arachnids typically have eight legs (four pairs), distinguishing them from insects (three pairs) and most crustaceans. (True)
• iii. They lack compound eyes: While some arachnids have simple eyes (ocelli), they generally lack compound eyes, which are characteristic of many insects and crustaceans. (True)
• iv. Body is divided into head, thorax and abdomen: Arachnids typically have a body divided into two main parts: a cephalothorax (fused head and thorax) and an abdomen. The division into a distinct head, thorax, and abdomen is characteristic of insects. (False)

Therefore, statements (i), (ii), and (iii) are correct.
This corresponds to option A.
