Which sequence correctly depicts the development of offspring?

A
zygote ® fetus ® embryo ® blastocyst
B
blastocyst ® embryo ® fetus ® zygote
C
fetus ® embryo ® blastocyst ® zygote
D
zygote ® blastocyst ® embryo ® fetus
4

Drinking alcohol during pregnancy negatively impacts development of the fetus because

A
the mother’s body is unable to process alcohol.
B
alcohol crosses the placental barrier.
C
the mother can no longer produce primary oocytes.
D
alcohol causes the mother to have facial distortions.
5

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because

A
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
B
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
C
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
D
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.
6

What is one difference between a primary oocyte and a secondary oocyte in humans?

A primary oocyte contains 46 chromosomes, while a secondary oocyte contains 23 chromosomes.

C
A primary oocyte develops in both men and women, while a secondary oocyte develops only in women.

B
The fetus differentiates into the embryo and the placenta.
C
The embryo has more cells than the fetus has.
D
The fetus is more developed than the embryo.
12

Which sequence correctly represents the order of events during egg formation?

A
primary oocyte ® secondary oocyte ® meiosis I ® meiosis II ® ovum
B
ovum ® meiosis I ® primary oocyte ® meiosis II ® secondary oocyte
C
primary oocyte ® meiosis I ® secondary oocyte ® meiosis II ® ovum
D
primary oocyte ® meiosis I ® ovum ® meiosis II ® secondary oocyte
13

Which best describes oogenesis?

A
Oogenesis involves mitosis but not meiosis.
B
Oogenesis differentiates oogonia directly into eggs.
C
Oogenesis starts in development and then halts until puberty.
D
Oogenesis happens in the testes.
14

Which of the following is a part of male gamete formation, but not a part of female gamete formation?

testes
B
ovaries
C
germ cells
D
oogonia
15
