A friend in your dormitory, a freshman, tells you that she just discovered she is 3 months pregnant. You know that since she came to college she has been experimenting with recreational drugs. Circle the best advice you could give her, and explain your choice. (a) She must stop taking the drugs, but they could not have affected her fetus during these first few months of her pregnancy. (b) Harmful substances usually cannot pass from mother to embryo, so she can keep using drugs. (c) There could be defects in the fetus, so she should stop using drugs and visit a doctor as soon as possible. (d) If she has not taken any drugs in the last week, she is OK.
An oophorectomized monkey is treated with high doses of estrogen. Which of the following changes is most likely to occur in the endometrium after 1 year of treatment? (A) Atrophy B Hyperplasia (C) Hypertrophy (D) Hypoplasia (E) Metaplasia
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.

A human is a complex organism that develops from a zygote. Briefly explain some of the the steps in this development process in the form of a paragraph. In your answer, be sure to: 1) explain how a zygote formed, 2) compare the genetic content of the zygote to the body cells of the parents, 3) identify the structure in which embryonic/fetal development usually occurs within, and 4) identify the structure that forms, which provides nourishment and waste removal to/from the developing baby.
