Which of the following statements does NOT correctly describe the events following fertilization?
Select one:
a. Only the inner cell mass cells in a blastocyst are pluripotent.
b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding.
c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican.
d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.
During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum?
Select one:
a. The corpus luteum produces relaxin, which thickens the endometrium.
b. The corpus luteum ensures that the endometrium does not break down during the first trimester.
c. The corpus luteum supports the formation of the placenta.
d. The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.
Which of the following structure develops into only the fetus?
A. Blastocyte
B. Zygote
