1. What is the term for the number of moles of solute per liter of solution?

Correct answer: A

Rationale: Molarity is the correct term for the number of moles of solute per liter of solution. It is expressed as moles of solute divided by liters of solution. Molality (B) is similar but is moles of solute per kilogram of solvent. Normality (C) is the number of equivalents of solute per liter of solution, and Concentration (D) is a general term for the amount of solute present in a given quantity of solution. Therefore, the correct answer is A, molarity, as it specifically refers to moles of solute per liter of solution.

2. Which of the following structures is located in the pelvic cavity?

Correct answer: C

Rationale: The correct answer is the bladder. The bladder is situated in the pelvic cavity, specifically in the lower part of the abdomen. The kidneys are positioned higher up in the abdominal cavity, not in the pelvic region. The colon and rectum are part of the large intestine and are primarily located in the abdominal cavity, not the pelvic cavity. Therefore, the bladder is the only structure listed that is anatomically situated in the pelvic cavity.

3. What are the fluid-filled sacs that cushion the brain within the skull called?

Correct answer: B

Rationale: The correct answer is B, cerebrospinal fluid. Cerebrospinal fluid acts as a shock absorber, protecting the brain from impact and providing nutrients to brain cells. Meninges are the three protective layers of tissue that surround the brain and spinal cord. Dura mater and arachnoid mater are specific layers of the meninges, not the fluid-filled sacs that cushion the brain.

4. What is the name of the wart-like growths caused by the human papillomavirus (HPV)?

Correct answer: C

Rationale: The correct answer is 'Papillomas.' Papillomas are benign wart-like growths caused by the human papillomavirus (HPV). Keloids are raised scars that occur at the site of an injury due to excessive collagen formation, while carcinomas are malignant tumors arising from epithelial cells. When identifying the growths specifically related to HPV, papillomas are the most appropriate term.

5. Which structure in the body is responsible for producing testosterone?

Correct answer: C

Rationale: The correct answer is C: Testes. The testes are responsible for producing testosterone, the hormone that plays a crucial role in male secondary sexual characteristics such as facial hair, deepening of the voice, and muscle development. The adrenal glands primarily produce cortisol and aldosterone, not testosterone. The pituitary gland regulates hormone production in various glands, including the testes, but it does not directly produce testosterone. The pancreas is responsible for producing insulin and glucagon to regulate blood sugar levels, not testosterone.
