_________ is an example of a viviparous animal.

Correct Answer: A

Rationale: The correct answer is A: Goat. Viviparous animals give birth to live young instead of laying eggs. Goats fall under this category as they give birth to live kids. Ducks (B) are oviparous, laying eggs. Crocodiles (C) are also oviparous, laying eggs. Choice D is incorrect as goats are viviparous animals.

Correct Answer: A

Rationale: The correct answer is A: Lymphatic vessels. Line "A" typically points to lymphatic vessels because they play a crucial role in draining excess fluid and waste products from tissues. They help maintain fluid balance and immunity. The other choices are incorrect because the pampiniform plexus is a network of veins in the spermatic cord, the internal spermatic fascia is a layer of connective tissue surrounding the spermatic cord, and the spermatic cord is a structure containing blood vessels, nerves, and ducts that support the testes. These structures are closely related anatomically but serve different functions compared to lymphatic vessels.

Correct Answer: C

Rationale: The correct answer is C: Candidiasis. Candidiasis is a fungal infection caused by the Candida fungus, commonly affecting the reproductive system. It can cause symptoms like itching, burning, and abnormal discharge. A: Syphilis is a bacterial infection transmitted through sexual contact. B: Gonorrhea is a bacterial infection affecting the reproductive system. D: Genital Herpes is a viral infection that affects the genital area. In summary, Candidiasis is the only fungal disease listed, making it the correct choice for a fungal infection of the reproductive system.

Correct Answer: C

Rationale: Step 1: Pelvic inflammatory disease (PID) is an infection of the fallopian tubes and pelvic organs. Step 2: PID is commonly caused by gonococcus or chlamydia infections. Step 3: Ovarian cyst (A) is a fluid-filled sac on the ovary, not related to infections. Step 4: Endometriosis (B) is the growth of endometrial tissue outside the uterus, not typically associated with infections. Step 5: Cervicitis (D) is an inflammation of the cervix, not involving the fallopian tubes and pelvic organs.

Correct Answer: B

Rationale: Exenteration involves the removal of internal organs from a body cavity, often performed in cases of advanced cancer or severe infection. This procedure is extensive, removing multiple organs or structures within a body cavity. Conization is a surgical procedure to remove a cone-shaped piece of tissue, typically from the cervix. Dissection involves cutting through tissues for examination or study, not necessarily removing organs. Cauterization is the process of burning tissue to stop bleeding or remove unwanted tissue, not specifically related to removal of organs from a body cavity. Therefore, the correct answer is B because it specifically describes the removal of internal organs from a body cavity.
