1. What is the area of a rectangular room with a length of 12 meters and a width of 10 meters?

Correct answer: A

Rationale: The correct answer is A: 120 square meters. To find the area of a rectangle, you multiply its length by its width. In this case, the length is 12 meters and the width is 10 meters. Therefore, the area of the room is 12m * 10m = 120 square meters. Choices B, C, and D are incorrect as they do not correctly calculate the area of the room based on its dimensions.

2. A cell from heart muscle would more than likely contain an unusually high proportion of which of the following?

Correct answer: B

Rationale: A cell from heart muscle would more than likely contain an unusually high proportion of mitochondria because the heart muscle requires a significant amount of energy to function properly. Mitochondria are the powerhouse of the cell and are responsible for producing energy in the form of ATP through cellular respiration. Therefore, to meet the high energy demands of the heart muscle, it would need a higher concentration of mitochondria compared to other cell types. Choices A, C, and D are incorrect because while lysosomes, mRNA, and ribosomes are essential components of a cell, they do not play as direct a role in meeting the high energy demands of heart muscle as mitochondria do.

3. Which phrase is NOT used correctly in the sentence?

Correct answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.

4. Which hormone is produced by the adrenal cortex?

Correct answer: B

Rationale: The correct answer is B, Cortisol. Cortisol is the hormone produced by the adrenal cortex. It plays a crucial role in regulating metabolism, immune response, and managing stress. Insulin is produced by the pancreas, thyroxine by the thyroid gland, and glucagon by the pancreas. Therefore, choices A, C, and D are incorrect as they are not hormones produced by the adrenal cortex.

5. Which molecule is primarily responsible for storing energy in cells?

Correct answer: B

Rationale: ATP is the correct answer because it is the molecule responsible for storing and providing energy in cells. Glucose is a source of energy but not primarily for storage. Fatty acids are more involved in energy production through oxidation. Starch is a polysaccharide used for energy storage in plants.
