Multiple choice

Match the 'Sex hormones' in Group - I with 'their roles' in Group - II.

 
Group - I Group - II
P. HCG 1. Secretion of kisspeptin
Q. Relaxin 2. Birth process
R. Estrogen 3. Promotes ovulation
S. LH 4. Prevents the deterioration of corpus luteum

  1. P - 1, Q - 4, R - 2, S - 3

  2. P - 4, Q - 2, R - 1, S - 3

  3. P - 3, Q - 2, R - 1, S - 4

  4. P - 4, Q - 3, R - 2, S - 1

  5. P - 2, Q - 4, R - 1, S - 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Correct answer. HCG (human chorionic gonadotropin) prevents the deterioration of the corpus luteum at the end of the fourth week and enables pregnancy to continue beyond the end of the normal menstrual cycle. Relaxin promotes angiogenesis, and in humans it probably plays a more important role in the development of the interface between the uterus and the placenta that it does in the birth process. High levels of estrogen inhibit the secretion of kisspeptin and suppress further production of those hormones. LH (luteinizing hormone) promotes ovulation, the release of the secondary oocyte into the fallopian tube. Hence, the correct sequence of codes is P - 4, Q - 2, R - 1, S - 3.
