Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.

- A. Nipples become prominent and mobile.
- B. Colostrum can be expressed.
- C. Breasts become tender.

Correct Answer: D
Rationale: During the 34-40 weeks of pregnancy, Montgomery's tubercles become prominent. These are sebaceous glands on the areola, not the nipples. Choice A is incorrect as it describes the changes in nipples, not Montgomery's tubercles. Choice B is incorrect as colostrum production usually starts around the 16th week. Choice C is incorrect as breast tenderness is more common in early pregnancy due to hormonal changes.
What does the umbilical cord contain?
- A. Pluripotent stem cells
- B. Cord blood stem cells
- C. Blood stem cells
- D. None of the above
Correct Answer: B
Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

Glandular tissue (Choice D) is a broad term referring to tissue containing glands, but it does not specifically line the uterus.
