Final answer:
The fetus does not gains most of its weight during the second trimesterThus the given statement is False.
Step-by-step explanation:
While the second trimester is a crucial period for the fetus's development, it's not when most of the weight gain occurs. The fetus undergoes rapid growth during the second trimester, but it's in the third trimester when a significant portion of the weight gain takes place. By the end of the second trimester, the fetus is still relatively small compared to its size at birth. On average, a fetus weighs around 1.5 to 2.5 pounds by the end of the second trimester, but it more than triples or quadruples that weight by the end of the third trimester.
Throughout the pregnancy, the fetus experiences continuous development, but the rate of growth tends to accelerate significantly in the final trimester. During this period, the fetus gains a substantial amount of weight as it prepares for birth. By the end of the third trimester, a full-term fetus can weigh anywhere between 6 to 9 pounds or more, showing the most significant weight gain compared to the earlier trimesters.
While the second trimester is crucial for the fetus's development, including the growth of organs and the development of features, the majority of the weight gain occurs in the final trimester. This period is marked by the fetus putting on significant layers of fat and muscle, essential for its survival and readiness for life outside the womb.
