Answer to Question 1

ANS: C
Dizygotic twins arise from two ova that are fertilized by different sperm. They may be the same or different gender, and they may not have similar physical traits. Monozygotic twins are always the same sex. A single fertilized ovum that produces twins is called monozygotic. Dizygotic twins are from two fertilized ova and may or may not be the same sex.

Answer to Question 2

ANS: D
Amniotic fluid and not the placenta helps with thermoregulation. The remaining statements are correct regarding placental function.
