1. Why is abortion important?

• A. It is easily conducted
• B. It can easily be diagnosed
• C. It causes serious complications such as infections and maternal death
• D. All of the above

Correct answer: C

Rationale: Abortion is important due to the serious complications it can cause, such as infections and maternal death. Choices A and B are incorrect because ease of conducting or diagnosing abortion procedures does not inherently make abortion important. Choice D is incorrect because not all the options listed are reasons why abortion is important; only choice C highlights the critical aspect of potential complications.

2. Approximately how many primordial follicles are present in the cortex of the ovary at birth?

• A. 250,000
• B. 200,000
• C. 150,000
• D. 100,000

Correct answer: A

Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.

3. What is the function of luteinizing hormone?

• A. Maintains the corpus luteum
• B. Ripens the Graafian follicle
• C. Prepares the breasts for lactation
• D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

4. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

5. What type of epithelium lines the fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.
