1. 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.

2. Which of the following is subsidiary uterine support?

• A. Suspensory ligament
• B. Cardinal ligament
• C. Transcervical ligament
• D. Maklouf ligament

Correct answer: B

Rationale: The correct answer is B: Cardinal ligament. The cardinal ligament is a primary uterine support structure that helps to anchor the uterus in place. The suspensory ligament also provides support for the uterus but is not considered a subsidiary uterine support. The transcervical ligament does not exist in anatomical terminology. The Maklouf ligament is a fictitious term and not recognized as a subsidiary uterine support structure.

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. After fertilization, cell division occurs through a process of:

• A. Binary fission
• B. Meiosis
• C. Budding
• D. Mitosis

Correct answer: D

Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.

5. Herpes simplex type 2 (HSV-2) does not cause cold sores of the lips:

• A. True.
• B. False.
• C. Depends on the person.
• D. Not enough information.

Correct answer: B

Rationale: Herpes simplex type 2 (HSV-2) typically causes genital herpes, not cold sores on the lips. Cold sores on the lips are commonly caused by herpes simplex type 1 (HSV-1). Therefore, the statement that HSV-2 causes cold sores of the lips is incorrect. Choice B, 'False,' is the correct answer. Choice A is incorrect because HSV-2 does not cause cold sores on the lips. Choice C, 'Depends on the person,' is incorrect as the cause of cold sores is predominantly linked to HSV-1. Choice D, 'Not enough information,' is also incorrect as this information is well-established in medical knowledge.
