,3|Page
C. Males have all the sperm at birth that will be made during their lifetime
D. Each primary spermatocyte produces four viable gametes
E. Each gamete has a total of 46 chromosomes - ANSWER-D. Each
primary spermatocyte produces four viable gametes
Discuss in detail the action of sperm needed to fertilize an egg - ANSWER-
The egg releases chemicals that attract the sperm. Sperm cells release
enzymes that break apart of the corona radiata, follicle cells surrounding
the egg. Once this is accomplished, more sperm release acrosomal enzymes
that make a hole in the membrane of the egg, allowing one sperm cell to
combine with the egg. When the union of egg and one sperm occurs, the
membrane of the egg instantly chemically changes, preventing other sperm
from penetrating the egg Which of the following is false concerning human
cells
A. Haploid cells contain half the number of chromosomes
B. Diploid cells contain the full number of chromosomes
C. Gamete cells are haploid cells
D. A zygote has 23 chromosomes
E. A and B are false - ANSWER-D. A zygote has 23 chromosomes
Discuss the supportive cells of the blastocyte and their purpose during
pregnancy - ANSWER-Amnion: forms a sac filled with fluid to cushion
and protect the fetus Placenta: is a temporary organ that carries out
nutritive, respiratory, excretory, and enforcing functions for the embryo
Umbilical cord: attaches the embryo to the placenta
