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

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.

2. What is the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births?

Correct answer: D

Rationale: To calculate the estimated percentage of deaths due to unsafe abortions, you divide the number of deaths due to unsafe abortions by the total number of maternal deaths and then multiply by 100 to get the percentage. In this case, with 591 maternal deaths and 40% estimated to be due to unsafe abortions, the calculation is (591 * 0.4) / 100, which equals 2.36. Therefore, the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births is 0.4 or 40%. Choices A, B, and C are incorrect percentages that do not reflect the provided information.

3. In the past, when was a woman only allowed to access Family planning methods?

Correct answer: C

Rationale: In the past, women were often required to produce a letter of consent from their husband to access family planning services. This requirement stemmed from traditional beliefs and societal norms that placed men in control of such decisions. Choice A is incorrect because marital status alone did not determine access to family planning. Choice B is incorrect because the number of children a woman had did not dictate her access to family planning. Choice D is incorrect because medical recommendations alone did not influence a woman's access to family planning services in the past.

4. Basal body temperature rise of _____ is seen in the luteal phase due to the thermogenic effects of a metabolite of progesterone in a normal cycle:

Correct answer: B

Rationale: A basal body temperature rise of 0.2-0.5 degrees Celsius is typically seen in the luteal phase of the menstrual cycle due to the thermogenic effects of a metabolite of progesterone. This temperature rise helps to indicate ovulation has occurred. Choices A, C, and D are incorrect as they do not reflect the usual range of temperature increase observed during the luteal phase. A rise of 0.1-0.5 degrees Celsius is too narrow (eliminating choice A), while ranges of 1.0-2.0 and 1.5-2.0 degrees Celsius are too high and not consistent with the expected basal body temperature changes during the menstrual cycle.

5. Which of the following hormones promotes endometrial growth?

Correct answer: C

Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.
