1. 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:

• A. 0.1-0.5
• B. 0.2-0.5
• C. 1.0-2.0
• D. 1.5-2.0

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.

2. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

3. 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.

4. The _________ is a temporary organ that connects a mammalian mother to its foetus.

• A. Placenta
• B. Chorion
• C. Endometrium
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus. It plays a crucial role in facilitating the exchange of nutrients, oxygen, and waste between the mother and the developing baby. Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.

5. A diet rich in _______ controls menopause symptoms:

• A. Carbohydrates
• B. Soya items
• C. Fruits and veggies
• D. Eggs and meat

Correct answer: B

Rationale: A diet rich in soya items can help control menopause symptoms. Soya contains phytoestrogens, which are plant-based compounds that mimic the hormone estrogen in the body. These compounds may help alleviate menopause symptoms such as hot flashes and night sweats. Choice A, Carbohydrates, do not specifically target menopause symptoms. Choice C, Fruits and veggies, while generally healthy, do not have the same impact on menopause symptoms as soya. Choice D, Eggs and meat, do not contain phytoestrogens like soya, making them less effective in managing menopause symptoms.
