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. Which of the following is NOT a phase of the menstrual cycle?

Correct answer: D

Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.

3. At 16 weeks of pregnancy, the breast changes include:

Correct answer: C

Rationale: At 16 weeks of pregnancy, the sensation of prickling and tingling in the breasts is common due to hormonal changes. Montgomery's tubercles becoming prominent is more characteristic of early pregnancy, typically around the first trimester. Darkening of the nipple, known as areola darkening, can occur but is more commonly observed later in pregnancy. The expression of colostrum, the first milk produced by the mammary glands, usually happens closer to the end of pregnancy or after childbirth, not typically at 16 weeks.

4. How does the component of Adolescent health and development empower adolescents/youths?

Correct answer: A

Rationale: The correct answer is A: By equipping them with life skills. Life skills empower adolescents and youths to make informed decisions and take control of their health. Providing health education (choice B) and encouraging them to become peer educators (choice C) are beneficial but may not directly empower them as much as acquiring life skills. Giving loans to start businesses (choice D) is not directly related to empowering adolescents in the context of health and development.

5. The menstrual disorder in which there is an absence or suppression of the normal menstrual period is called:

Correct answer: D

Rationale: Amenorrhoea is the correct term for the absence or suppression of the menstrual period. Dysmenorrhoea refers to painful menstruation, Polymenorrhoea is characterized by frequent, short menstrual cycles, and Menorrhagia is excessive menstrual bleeding. Therefore, 'Amenorrhoea' is the most appropriate term for the described menstrual disorder.
