1. During which phase of the menstrual cycle does the Graafian follicle rupture?

• A. Regenerative
• B. Menstruation
• C. Ovulation
• D. Proliferative

Correct answer: C

Rationale: The correct answer is C: Ovulation. The Graafian follicle ruptures during the ovulation phase, releasing the mature egg from the ovary. This process marks the midpoint of the menstrual cycle. Choice A, Regenerative, is incorrect as it does not correspond to a specific phase of the menstrual cycle. Choice B, Menstruation, is incorrect because menstruation is the shedding of the uterine lining and occurs after ovulation if fertilization does not occur. Choice D, Proliferative, is incorrect as it refers to the phase in which the uterine lining thickens in preparation for a potential embryo implantation, which happens after ovulation.

2. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

3. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. Legislation allowing nursing staff to provide contraceptives has resulted in all of the following EXCEPT:

• A. More nursing staff have been trained to provide family planning services
• B. Many population and family planning organizations have emerged
• C. Enhanced implementation of population and family planning programs
• D. Male involvement in family planning services

Correct answer: D

Rationale: The correct answer is D. Male involvement in family planning services has not significantly resulted from legislation allowing nursing staff to provide contraceptives. While legislation has led to more nursing staff being trained, the emergence of population and family planning organizations, and enhanced implementation of programs, it has not directly impacted male involvement in family planning.

5. Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?

• A. Recruitment of Graafian follicle
• B. Selection of dominant follicle
• C. Luteal phase
• D. Formation of corpus luteum

Correct answer: A

Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.
