A. Haploid cells contain the full number of chromosomes (46). B. Diploid cells contain half the number of chromosomes (23). C. Gamete cells are haploid cells. D. A zygote has 23 chromo- somes. E. A&B are true
When the union of egg and one sperm occurs, the membrane of the egg instantly chemically changes, preventing other sperm from penetrating the egg.
C. Gamete cells are haploid cells.
- Discuss the supportive cells of (The amnion, placenta and umbilical cord.) The amnion forms the blastocyst and their pur- pose during pregnancy.
- Label each of the following as occurring during the: 1st
a sac filled with fluid to cushion and protect the fetus. The placenta is a temporary organ that carries out nutritive, respi- ratory, excretory and endocrine functions for the embryo. The baby continues to grow in the uterus with nutrition provided by the placenta for nine months until it is time for delivery. The umbilical cord attaches the embryo to the placenta.

- Discuss in detail the layers of the cells (blastocyst) which form the embryo.
- Which of following state- ments are true regarding the female reproductive system: A. The bladder is located pos- terior to the uterus. B. The rectum is located ante- rior to the uterus. C. The ovaries are the site of estrogen and egg produc- tion. D. It contains the site of the vas deferens
in the oviducts forming the morula and another three to four days undergoing mitosis while unattached in the uterus, form- ing the blastocyst as the endometrium prepares for implanta- tion. Because of progesterone release from the corpus luteum, the endometrium increases its blood supply and secretes glycogen. The blastocyst implants into the endometrium of the uterus around day 7.
The skin and nervous tissue develop from the outer ectoderm layer.
The inner endoderm layer forms the glands (thyroid, parathy- roid, and thymus), solid organs (liver and pancreas), and the lining of the hollow organs of the digestive and respiratory systems.
All other tissues, including the cardiovascular system, red blood cells, and muscle develop from the middle mesoderm layer.
C. The ovaries are the site of estrogen and egg production.
