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.

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.

Correct Answer: D

Rationale: The correct answer is D: rising levels of luteinizing hormone. Luteinizing hormone surge triggers ovulation by stimulating the release of the mature egg from the ovary. This surge is a crucial event in the menstrual cycle. A: Follicle stimulating hormone is involved in follicular development, not ovulation. B: Progesterone levels rise after ovulation, not before. C: Oestrogen levels actually rise before ovulation to trigger the LH surge, so a drop in oestrogen levels would not initiate ovulation.

Correct Answer: D

Rationale: The correct answer is D: the oviduct. Fertilization occurs in the oviduct, specifically in the ampulla region. Sperm meets the egg in the oviduct where fertilization takes place. The other choices, A: the uterus, B: the vagina, and C: the ureter, are incorrect because fertilization does not occur in these locations. The uterus is where the fertilized egg implants and develops into a fetus. The vagina is the passage for sperm to enter the reproductive system. The ureter is a tube that connects the kidney to the bladder, and is not involved in fertilization.

Correct Answer: C

Rationale: The correct answer is C: prostate. The prostate gland secretes proteolytic enzymes such as prostate-specific antigen (PSA) to liquefy semen. This aids in sperm mobility and overall fertility. The other choices are incorrect because: A: bulbourethral gland secretes a clear fluid to lubricate the urethra during sexual arousal. B: urethra is a passageway for urine and semen but does not secrete proteolytic enzymes. D: testis produces sperm cells but does not secrete enzymes to liquefy semen.
