Francesca, who is pregnant, has just felt the first movements of her developing offspring. given what you know about prenatal development, at which month of pregnancy would you estimate francesca to be?

Fourth

Explanation:

The pregnant woman usually feels the baby moving the belly for the first time between the 16th and 20th weeks of gestation, that is, at the end of the 4th month or during the 5th month of pregnancy. However, in the second pregnancy, it is normal for the mother to feel the baby move earlier, between the end of the 3rd month and the beginning of the 4th month of pregnancy.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
