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.

2. Appropriate Technologies and Skills involve:

A. Selecting technologies according to universal standards.
B. Ensuring a doctor is present at the service-providing facility.
C. Requiring that health care providers are nurses.
D. Selecting technologies that are easy to use but not necessarily effective.

Correct answer: A

Rationale: The correct answer is A: 'Selecting technologies according to universal standards.' Appropriate technologies and skills involve choosing tools and methods based on universal standards to ensure effectiveness and efficiency. Choice B is incorrect because the presence of a doctor is not necessarily a defining factor for appropriate technologies and skills. Choice C is incorrect as appropriate technologies are not limited to being utilized only by nurses. Choice D is incorrect as the focus should be on selecting technologies that are both easy to use and effective, not one or the other.

3. What is dysmenorrhoea?

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.

4. Menopausal women require a diet rich in calcium to prevent osteoporosis. Which one of the following is a source of calcium?

A. Spinach
B. Cabbage
C. Carrots
D. Rape

Correct answer: A

Rationale: Corrected Rationale: Spinach is a good source of calcium, which is crucial for preventing osteoporosis in menopausal women. Spinach is a leafy green vegetable high in calcium content. While cabbage, carrots, and rape are nutritious, they do not provide as much calcium as spinach does. Therefore, spinach is the correct choice for menopausal women looking to increase their calcium intake.

5. 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.
