1. 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.

A. Heavy menstruation
B. Light menstruation
C. Painful menstruation
D. Infrequent menstruation

Correct answer: C

Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.

A. Community participation
B. Peer consultation
C. Multi-sectoral approach
D. Appropriate technology

Correct answer: C

Rationale: A multi-sectoral approach involves collaboration among various sectors and stakeholders to address complex issues comprehensively. In this context, it ensures that different entities work together to provide inclusive and effective services. Choice A, 'Community participation,' focuses more on the involvement of the community specifically. Choice B, 'Peer consultation,' pertains to seeking advice or input from peers within the same field. Choice D, 'Appropriate technology,' refers to the use of suitable technology for a particular situation, which is not the primary focus of the described system.

4. Which of the following are examples of external genitalia?

A. Mons veneris
B. Labia majora
C. Vagina
D. Cervix

Correct answer: A

Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.

5. Which hormone is released from the testes?

A. Progesterone
B. Vasopressin
C. Testosterone
D. None of the above

Correct answer: C

Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.
