which of the following statements are true with regard to fertilization?
□ fertilization is the presence of a developing offspring in the uterus.
□ fertilization takes place in the uterine tube.
□ fertilization can take place without male gametes present.
□ fertilization is complete when sperm and egg nuclei unite.
□ fertilization consists of three periods called trimesters, each about three months long.

Explanation:

• Fertilization occurs in the uterine tube (fallopian tube), not the uterus. So the first statement is false.
• Fertilization does take place in the uterine tube. So the second statement is true.
• Fertilization requires male gametes (sperm) and female gametes (egg). So the third statement is false.
• Fertilization is complete when sperm and egg nuclei unite. So the fourth statement is true.
• Pregnancy (not fertilization) consists of three trimesters. So the fifth statement is false.

Answer:

B. Fertilization takes place in the uterine tube.
D. Fertilization is complete when sperm and egg nuclei unite.
