Question

During gestation, embryos normally develop in _____.

Answer 1

Gestation is the period of the embryo or the baby in the mother's womb from the moment it is conceptualized to the moment it is born out of the mother's body. The gestation of a woman normally lasts from 37 to 41 weeks. It is measured from the last day of menstruation of the mother to the natal day of the baby

Answer 2

During gestation, embryos normally develop in humans which happen in the eleventh week. An embryo is then called a fetus in a more advanced stage of development. Unlike humans, animals which develop in eggs outside the mother's body would be then called as chick embryo.

The missing word in the sentence above is humans.
