The following statements about the prostate are true:

Correct Answer: A

Rationale: Step-by-step rationale for the correct answer (A): 1. The prostate gland is an exocrine gland because it secretes its products through ducts onto an epithelial surface. 2. It is a paired organ, with two lobes located above the urethra and below the bladder. 3. The prostate secretes a fluid that contributes to the seminal fluid, not semen itself. 4. The prostate is vascularized by branches of the internal iliac artery, not the entire gland. Therefore, the correct statement is that the prostate is an exocrine glandular organ (Choice A).

Correct Answer: B

Rationale: The correct answer is B because ovarian follicles are actually present in the ovary since birth. They are formed during fetal development and remain in a dormant state until puberty. Choice A is incorrect because follicles are located in the medullary area of the ovary, not the cortical area. Choice C is incorrect because follicles are formed before puberty. Choice D is incorrect because follicles do not go through stages of evolution but rather stages of development.

Correct Answer: D

Rationale: The correct answer is D: muscular. The uterus is composed of smooth muscle tissue, allowing it to contract during childbirth and menstruation. This contraction is essential for the expulsion of the fetus or uterine lining. Funnel-shaped (A) and cavitary (C) describe the shape and structure of the uterus, but they do not define its primary function. Unpaired (B) is incorrect as the uterus is a paired organ in the female reproductive system.

Correct Answer: B

Rationale: The correct answer is B: consists in the fusion between the male and female gametes. Fecundation, also known as fertilization, is the process where a sperm cell fuses with an egg cell to form a zygote. This is a crucial step in sexual reproduction. The male gamete (sperm) and the female gamete (egg) come together to combine their genetic material, resulting in the formation of a new individual. The other choices are incorrect because: A) Monospermic means involving only one sperm, which is not accurate as multiple sperm may reach the egg but only one will fertilize it. C) Grafting of the egg at the Fallopian tube is not how fertilization occurs; fertilization typically takes place in the fallopian tube but does not involve grafting. D) Fecundation does not require the existence of several fecundated spermatozoa; only one sperm is needed for fertilization to occur.

Correct Answer: C

Rationale: The correct answer is C: chromosome number. Human egg cells and sperm cells both have 23 chromosomes, which is half the total number of chromosomes in a human cell (46). This is crucial for maintaining the correct chromosome number in offspring. Choices A, B, and D are incorrect because: A: Human egg cells are not motile, while sperm cells are highly motile. B: Egg cells contain a larger amount of stored food (cytoplasmic material) compared to sperm cells. D: Egg cells are larger and rounder in shape, while sperm cells are smaller and more streamlined.
