Explanation / Answer

19. C. Sensitivity

Sensitivity is also called as Limit of detection or analytical sensitivity in assay methods. Hence, the answer is option C.

20. D. Sharp increase in LH(Leutinizing Hormone) production on approximately day 13 of the menstual cycle

Prolactin hormone is peak while beginnig of breastfeeding (45 minutes after starting breastfeeding) in responses to suckling

FSH (Follicle Stimulating Hormone) is high during the last few days of menstruation

Progesterone peak secretion is during the luteal phase (14-28 days)

Gonadotropic hormone production is more in the initial days of the menstrual cycle

Hence the correct answer is option D

21. D. Protein hormone

Testosterone is a steroid hormone but not a protein hormone produced from the leydig cells of testes and responsible for growth of genitalia (primary sexual characters) as well as secondary sexual characters like facial hair, deeper voice, adam's apple, broad chest etc. It is a principal androgen and necessary for spermatogenesis. So, the answer is option D

22. Option C. Secondary oocyte

Secondary oocyte is formed through meiosis I and consists of one pair of homologous chromosomes thus making it haploid. Remaining options are diploid.
