Biology Human Reproductive System Questions
Question 1 of 5
Which of the following is suitable for the fertilization of an egg?
Correct Answer: A
Rationale: The correct answer is A: Sperm. Sperm is the mature male reproductive cell capable of fertilizing an egg. It carries genetic material and is designed for the process of fertilization. Spermatid (B) is an immature sperm cell not yet capable of fertilizing an egg. Primary spermatocyte (C) is a cell undergoing meiosis to produce spermatids. Spermatogonium (D) is a stem cell that gives rise to spermatocytes but is not directly involved in fertilization. Therefore, only sperm (A) is suitable for fertilizing an egg.
Question 2 of 5
At the time of ovulation, each secondary oocyte is surrounded by a single layer of cells known as a(n) ________.
Correct Answer: A
Rationale: The correct answer is A: vesicular (Graafian) follicle. At the time of ovulation, the secondary oocyte is surrounded by this structure, which is a mature follicle containing a fluid-filled antrum. This structure is essential for the release of the oocyte during ovulation. The other choices, B: primary follicle, C: primordial follicle, and D: uterine (fallopian) follicle, are incorrect because primary follicles are immature, primordial follicles are the earliest stage of follicle development, and uterine (fallopian) follicle is not a correct anatomical term.
Question 3 of 5
Which structure provides a temporary
Correct Answer: A
Rationale: The correct answer is A, seminal gland, which provides a temporary storage site for immature sperm. Seminal glands are responsible for producing seminal fluid which nourishes and protects the sperm. The immature sperm are stored in the seminal gland until they mature. The other choices, B tunica albuginea, is a tough layer surrounding the testes, not involved in sperm storage. C ductus deferens is a tube that transports mature sperm from the epididymis to the urethra, not for storage of immature sperm. D is a duplicate of C, so it is incorrect.
Question 4 of 5
Failure of the testes to descend into mitotic cell divisions occur as the the scrotum is a condition known as zygote travels down the uterine ________.
Correct Answer: C
Rationale: The correct answer is C: cryptorchidism. Cryptorchidism is the condition where one or both testes fail to descend into the scrotum. This leads to impaired spermatogenesis as the temperature in the abdominal cavity is too high for proper sperm production. Phimosis (A) is the narrowing of the opening of the foreskin, unrelated to testicular descent. The acrosomal reaction (B) is a process during fertilization, not related to testicular descent. Cleavage (D) refers to the rapid mitotic cell divisions of the zygote, not associated with testicular descent.
Question 5 of 5
What effect does luteinizing hormone uterine (fallopian) tubes is called the (LH) have on a female?
Correct Answer: D
Rationale: Rationale: 1. LH is a hormone released by the pituitary gland. 2. Its main role in females is to trigger ovulation. 3. LH does not directly affect the uterine tubes or breast enlargement. 4. Therefore, the correct answer is D: "LH has no effect on a female." Summary: A, B, and C are incorrect because LH does not promote breast enlargement or affect the uterine tubes. The correct answer, D, is supported by the physiological functions of LH in the female reproductive system.
