Answer to Question 1

ANS: C
Human placental lactogen is responsible for glucose availability for the fetus and promotes fetal growth by altering maternal protein, carbohydrate, and fat metabolism. Estrogen has multiple functions, but these do not include regulating glucose availability. Human chorionic gonadotropin maintains the corpus luteum until the placenta has developed enough to produce adequate progesterone. Among other functions, progesterone helps suppress maternal immunological responses to fetal antigens.

Answer to Question 2

ANS: A
Embryonic stem cells have the ability to differentiate into any one of the 200 kinds of human cells that will be present at birth. The uterus secretes a mix of lipids, mucopolysaccharides, and glycogen that nourishes the blastocyst. The embryo develops from the blastocyst, and the placenta develops from the trophoblast.
