Answer 2

Answer:

The right answer is (2) Placenta takes over the production of progesterone and FSH.

Explanation:

• The pregnancy is divided into three trimesters.
• The first trimester is the most crucial in pregnancy and starts from week 1 to the end of week 12.
• In the first trimester placenta takes over the production of progesterone and FSH because of this nausea and vomiting are reduced.
• The second trimester starts from week 13 to the end of week 26 and in this trimester the organs of the fetus are fully developed.
• In the third trimester, the fetus develops in size and weight and is from week 27 to the end of the pregnancy.
• The mother may feel the movement and punching of the fetus in the third trimester.
• Therefore, the statement placenta takes over the production of progesterone and FSH is correct with respect to the first trimester.
