1. What does Bidder's canal receive?

• A. Eggs
• B. Sperms
• C. Ammonia
• D. Oxygenated blood

Correct answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

2. 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.

3. A woman is considered to be in menopause if she has experienced the cessation of her menses for a period of:

• A. 6 months
• B. 12 months
• C. 18 months
• D. 24 months

Correct answer: B

Rationale: Menopause is defined as the cessation of menses for 12 months. This period is significant because it indicates the end of a woman's reproductive years. Choices A, C, and D are incorrect as they do not align with the established criteria for defining menopause.

4. Which of the following is the most effective method of contraception?

• A. Barrier methods
• B. Hormonal pills
• C. Intrauterine devices (IUDs)
• D. Sterilization

Correct answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.

5. At 3-4 weeks of pregnancy, the breast changes include:

• A. Darkening of the nipple.
• B. Prickling, tingling sensation.
• C. Breast becomes tender.
• D. Colostrum can be expressed.

Correct answer: C

Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.
