Answer to Question 1

D
Oxygenated blood is transported to the fetus through the umbilical vein. The foramen ovale shunts blood through the fetal heart into the right atrium. Fetal arteries return deoxygenated fetal blood and fetal wastes to the placenta.

Answer to Question 2

C
Before 28 weeks' gestation, the preterm female infant may have a prominent clitoris with small separated labia. Eyes are fused prior to 24 weeks' gestation. Plantar creases over two-thirds of sole occurs after 36 weeks' gestation. Lanugo balding on back and arms occurs after 36 weeks' gestation.
