Where is the majority of progesterone produced?

Correct Answer: B

Rationale: The correct answer is B: corpus luteum. Progesterone is primarily produced by the corpus luteum, which forms from the ruptured ovarian follicle after ovulation. The corpus luteum secretes progesterone to prepare the uterus for potential implantation of a fertilized egg. The Graafian follicle (choice A) is a mature ovarian follicle that contains the egg, but it does not produce progesterone. The secondary follicle (choice C) is an immature ovarian follicle and does not produce progesterone. The adrenal cortex (choice D) is responsible for producing other hormones like cortisol and aldosterone, not progesterone.

Correct Answer: A

Rationale: The correct answer is A: Basking shark. Ovoviviparous animals are those that produce eggs that hatch inside the mother's body, giving birth to live young. Basking sharks exhibit this reproductive strategy, making them ovoviviparous. Explanation of incorrect choices: B: Bonobos are primates and give birth to live young, but they are not ovoviviparous. C: Blue sharks give birth to live young as well, but they are not ovoviviparous. D: "None of the above" is incorrect as the basking shark is indeed an ovoviviparous animal, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Suspensory ligament. This ligament arises from the pubic symphysis in males and supports the male reproductive organs. It helps suspend the penis and testes in the scrotum. The Fundiform ligament (A) supports the penis, the Broad ligament (B) supports the uterus, and the Ejaculatory ligament (D) is not a ligament associated with the pubic symphysis in males.

Correct Answer: A

Rationale: The correct answer is A: Ductus epididymis. Line "F" is pointing to the ductus epididymis, which is a part of the male reproductive system where sperm mature and are stored. The ductus epididymis is located at the top of the testis and is connected to the rete testis. It is responsible for transporting sperm from the testis to the vas deferens. Explanation for incorrect choices: B: Rete testis - The rete testis is a network of tubules located within the testis, not the ductus epididymis. C: Efferent duct - Efferent ducts are small ducts that connect the rete testis to the epididymis, not the ductus epididymis itself. D: Afferent duct - Afferent ducts are responsible for transporting sperm from the rete testis to the epididymis, not within the epid

Correct Answer: C

Rationale: The correct answer is C: Increasing the rate and depth of breathing during sexual arousal. The reproductive system does not directly contribute to the rate and depth of breathing. The main function of the reproductive system is to produce and deliver gametes for reproduction. It does not have a direct role in regulating respiratory functions. Choices A, B, and D are incorrect because the reproductive system does contribute to maintaining bone health, regulating cholesterol levels in males, and stimulating muscle growth in males. These functions are known contributions of the reproductive system to the body systems.
