1. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

2. Which part of the female reproductive system remains blocked after tubectomy?

• A. Fallopian tube
• B. Cervix
• C. Uterine cavity
• D. None

Correct answer: A

Rationale: After a tubectomy procedure, the Fallopian tube remains blocked. This is the correct answer because tubectomy involves the surgical blocking or sealing of the Fallopian tubes to prevent eggs from reaching the uterus, thus preventing pregnancy. Choice B, the cervix, is incorrect as it is not blocked during a tubectomy. Choice C, the uterine cavity, is also incorrect as the procedure does not involve blocking this part of the reproductive system. Choice D, none, is incorrect as the purpose of tubectomy is to block the Fallopian tubes.

3. 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.

4. Which of the following is an example of an oviparous animal?

• A. Pigeon
• B. Elephant
• C. Sheep
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.

5. Amniocentesis deals with patterns of ______ in the amniotic fluid.

• A. Fingers
• B. DNA
• C. Chromosomes
• D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.
