Question

question 9
which of the following occurs during the last two months of pregnancy?
○ the heartbeat begins
○ irregular breathing begins
○ organogenesis occurs
○ fatty tissues develop

Explanation:

1. Analyze each option:

• "the heartbeat begins": The fetal heartbeat begins much earlier (around 5 - 6 weeks of gestation), not in the last two months.
• "irregular breathing begins": Fetal breathing - like movements start earlier, and irregular breathing patterns are not a main event in the last two months.
• "organogenesis occurs": Organogenesis (formation of organs) occurs in the first trimester (first three months), not the last two months.
• "fatty tissues develop": In the last two months of pregnancy (third trimester, especially the later part), the fetus gains weight, and fatty tissues (adipose tissue) develop to help with temperature regulation and energy storage after birth.

Answer:

D. fatty tissues develop
