Which hormone helps the breast tissue prepare for milk production?

Correct Answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is the hormone responsible for helping breast tissue prepare for milk production by stimulating the growth of milk-producing glands and promoting the development of ducts. Estrogen supports breast development but is not directly involved in milk production. Prolactin is the hormone that actually stimulates milk production after childbirth. Oxytocin is responsible for releasing milk from the breast during breastfeeding, but it does not help in the preparation of breast tissue for milk production. Therefore, Progesterone is the correct answer as it plays a crucial role in preparing the breast tissue for milk production.

Correct Answer: B

Rationale: Estrogen regulates the menstrual cycle by promoting the growth of the uterine lining. It also triggers ovulation. This is a crucial function in female reproductive health. Other choices are incorrect because estrogen does not directly inhibit FSH release, support embryo implantation, or increase progesterone secretion. Estrogen's main role is in the menstrual cycle regulation.

Correct Answer: D

Rationale: The correct answer is D: Fallopian tube. Fertilization of the egg typically occurs in the fallopian tube where the sperm meets the egg to form a zygote. The fallopian tubes provide a suitable environment for fertilization to take place. The other choices (A: Uterus, B: Ovary, C: Cervix) are incorrect because fertilization does not occur in these locations. The uterus is where the fertilized egg implants and grows into a fetus, the ovary releases the egg during ovulation, and the cervix is the lower part of the uterus that connects to the vagina.

Correct Answer: C

Rationale: The correct answer is C: Produce sperm. Seminiferous tubules are the site of spermatogenesis, the process by which sperm are produced in the testes. Sperm cells are generated through a series of cell divisions and maturation processes within the seminiferous tubules. Therefore, the primary function of the seminiferous tubules in males is to produce sperm cells. A: Store sperm - While the epididymis and vas deferens are responsible for storing sperm, the seminiferous tubules are not primarily involved in sperm storage. B: Produce seminal fluid - Seminal fluid is produced by the accessory glands such as the prostate gland and seminal vesicles, not the seminiferous tubules. D: Transport sperm - Sperm transport occurs through the vas deferens and other ducts, not within the seminiferous tubules.

Correct Answer: A

Rationale: The correct answer is A: Prolactin. Prolactin is the hormone responsible for stimulating milk production after childbirth. It is produced by the pituitary gland and plays a key role in lactation. Oxytocin, another hormone, is responsible for milk ejection during breastfeeding, not milk production. Estrogen and progesterone are involved in regulating the menstrual cycle and pregnancy, not milk production. Therefore, the correct choice is A as it directly relates to milk production post-childbirth.
