Which of the following is a form of sexual reproduction?

Correct Answer: D

Rationale: Step 1: Define sexual reproduction as the process involving the fusion of gametes from two parents. Step 2: Hermaphroditism refers to an organism having both male and female reproductive organs for self-fertilization. Step 3: In hermaphroditism, there is still a fusion of gametes, fulfilling the criteria of sexual reproduction. Step 4: Fragmentation, parthenogenesis, and budding are forms of asexual reproduction, not involving the fusion of gametes. Step 5: Therefore, the correct answer is D (Hermaphroditism) as it aligns with the definition and process of sexual reproduction.

Correct Answer: B

Rationale: Rationale: The correct answer is B because excessive exercise can lead to decreased body fat, which in turn disrupts hormone levels causing irregular periods. Choice A is inappropriate as it doesn't address the underlying issue. Choices C and D are incorrect as they refer to different conditions (bulimia and anorexia) not related to the client's concern.

Correct Answer: B

Rationale: The correct answer is B: epididymis. Sperm cells attain fertilization competence and motility in the epididymis. Here's the rationale: 1. Sperm cells are produced in the seminiferous tubules of the testes. 2. They then move to the epididymis for maturation, where they gain motility and the ability to fertilize an egg. 3. The epididymis provides the ideal environment for sperm to undergo final maturation processes. 4. The rete testis is a network of tubules where sperm are transported from the seminiferous tubules, not where they gain fertilization competence. 5. The vas deferens is a duct that carries sperm from the epididymis to the urethra, not where sperm attain fertilization competence.

Correct Answer: B

Rationale: The correct answer is B: seminiferous tubule. FSH (follicle-stimulating hormone) targets the seminiferous tubules in the testes to stimulate the production of sperm. FSH plays a crucial role in male reproductive function by promoting spermatogenesis. The other choices are incorrect because: A: Prostate - FSH does not directly target the prostate. C: Pituitary - FSH is secreted by the pituitary gland, it does not target the pituitary itself. D: Penis - FSH does not have a direct role in the structure or function of the penis.

Correct Answer: A

Rationale: The correct answer is A: fimbriae. Fimbriae are finger-like projections at the end of the fallopian tube that capture the released oocyte from the ovary during ovulation. The fimbriae create a gentle sweeping motion to guide the oocyte into the uterine tube for fertilization. The other choices are incorrect because the oocyte needs to be captured by the fimbriae before entering the uterine tube, infundibulum, or uterus. The fimbriae are the initial structure responsible for receiving the oocyte, making choice A the correct answer.
