1. What is the term for the process of converting a liquid into a gas at a temperature below its boiling point?

Correct answer: B

Rationale: Evaporation is the correct term for the process of converting a liquid into a gas at a temperature below its boiling point. During evaporation, molecules of the liquid gain enough energy to escape into the gas phase, primarily occurring at the liquid's surface. Vaporization is a broader term that encompasses the conversion of a substance from a liquid or solid state to a gas, not specifically at temperatures below the boiling point. Condensation is the reverse process of evaporation, involving the conversion of a gas into a liquid. Sublimation, on the other hand, refers to the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase.

2. Which of the following hormones helps regulate blood pressure by affecting kidney function?

Correct answer: C

Rationale: Renin is the hormone that helps regulate blood pressure by affecting kidney function. It is released by the kidneys in response to low blood pressure or low blood volume. Renin plays a crucial role in the renin-angiotensin-aldosterone system, which is responsible for regulating blood pressure and fluid balance in the body. Insulin, testosterone, and estrogen do not directly impact blood pressure regulation through kidney function. Insulin is involved in regulating glucose metabolism, testosterone is a male sex hormone, and estrogen is a female sex hormone. Therefore, the correct answer is Renin (Choice C) because of its specific role in blood pressure regulation through kidney function.

3. Which of the following best defines the anatomical term medial?

Correct answer: C

Rationale: The correct definition of the anatomical term 'medial' is being close or near to the midline of the body. This term describes a position closer to the center or midline of the body, opposite to 'lateral' which refers to a position further away from the midline. Choice A, 'Being face down,' is incorrect as it describes the anatomical term 'prone.' Choice B, 'On the front of the body or limb,' is incorrect as it describes the anatomical term 'anterior.' Choice D, 'Above or on top of the lungs,' is incorrect as it does not relate to the term 'medial.'

4. Which element is essential for the formation of hemoglobin?

Correct answer: B

Rationale: The correct answer is Iron. Iron is essential for the formation of hemoglobin, the protein in red blood cells that binds and transports oxygen throughout the body. Calcium (Choice A), Potassium (Choice C), and Sodium (Choice D) are not directly involved in the formation of hemoglobin and its oxygen-carrying function.

5. How do killer T cells recognize infected cells?

Correct answer: D

Rationale: Killer T cells recognize infected cells by detecting viral proteins displayed on the surface of these cells. The T cells possess receptors specifically designed to identify these viral proteins, allowing them to target and eliminate the infected cells. Choice A is incorrect because B cells are not directly involved in the recognition process of infected cells by killer T cells. Choice B is incorrect because tiny bits of the virus's RNA being left around the cell is not how killer T cells primarily recognize infected cells. Choice C is incorrect because while macrophages play a role in immune responses, they do not directly assist in the recognition of infected cells by killer T cells.
