1. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

2. 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.

3. Which of the following is not a characteristic of an ideal contraceptive?

• A. Irreversible
• B. Easily available
• C. User-friendly
• D. Effective with least side effects

Correct answer: A

Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.

• C. 4 months
• D. 5 months

Correct answer: C

Rationale: The correct answer is C: '4 months.' The risk of endometrial hyperplasia is highest in individuals who do not menstruate for at least 4 months. This prolonged exposure to unopposed estrogen can lead to endometrial hyperplasia. Choices A, B, and D are incorrect because the risk is greatest after at least 4 months of not menstruating, not 2, 3, or 5 months.

Correct answer: A

Rationale: A Total Fertility Rate of 6.2 means that a woman will give birth to an average of 6.2 children during her childbearing years. The correct answer is A as it accurately reflects the concept of Total Fertility Rate. Choice B is incorrect as it misinterprets the concept by equating it to a percentage of time being pregnant. Choice C is incorrect as it does not relate to the Total Fertility Rate but rather to the success rate of deliveries. Choice D is incorrect as it introduces the idea of medical intervention, which is not directly related to the Total Fertility Rate.
