ii. State the function of placenta in the mother’s

body.

iii. At what interval the egg is formed in human

female ovary?​

Answer 1

Answer:

1) Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

2)The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

3) The egg erupts from the ovary on the 14th to 16th day of the approximately 28-day menstrual cycle. If not fertilized, the egg is passed from the reproductive tract during menstrual bleeding, which starts about two weeks after ovulation.
