1. Why is the nucleus important in a cell?

• A. It stores the DNA
• B. It supports the cell
• C. It makes protein
• D. It makes energy out of food

Correct answer: A

Rationale: The nucleus is important in a cell because it stores the DNA, which contains the genetic information necessary for the cell's function and replication. This genetic material controls the cell's activities and characteristics. Choices B, C, and D are incorrect because supporting the cell, making proteins, and producing energy are functions typically associated with other cell organelles like the cytoskeleton, ribosomes, and mitochondria, respectively.

2. What does the quoted word 'impending' mean in the following sentence?

• A. Very serious
• B. Required
• C. Elective
• D. Soon to occur

Correct answer: D

Rationale: The correct answer is D: 'Soon to occur.' The word 'impending' is used to describe something that is about to happen or is soon to occur. In the context of the sentence provided, 'impending' operation indicates that the operation is about to take place. Choices A, B, and C are incorrect because 'impending' does not mean 'very serious,' 'required,' or 'elective.' Instead, it specifically refers to the timing of the operation as being imminent.

3. What does the word Querulous mean?

• A. Shouting
• B. Complaining
• C. Crying
• D. Praising

Correct answer: B

Rationale: The correct answer is B: 'Complaining.' Querulous is an adjective that describes someone who is constantly complaining or irritable. It is not related to shouting (Choice A) or crying (Choice C). Choice D, 'Praising,' is the opposite of the meaning of querulous and therefore incorrect.

4. What action describes what a cat, who is clearly scared of a Rottweiler, will do when the dog enters the room?

• A. Cower
• B. Engender
• C. Enhance
• D. Replicate

Correct answer: A

Rationale: When a cat cowers, it means the cat is crouching down or trying to make itself look smaller in fear or apprehension of something, in this case, the Rottweiler. Hence, the word 'cower' accurately describes what the cat would do when faced with a Rottweiler entering the room. The other choices are incorrect: 'Engender' means to cause or give rise to, 'Enhance' means to improve or increase the quality or value of something, and 'Replicate' means to duplicate or reproduce something.

5. Which of the following structures has the lowest blood pressure?

• A. arteries
• B. arterioles
• C. venules
• D. veins

Correct answer: D

Rationale: Veins have the lowest blood pressure among the listed structures. This is because veins carry blood back to the heart at a slower rate compared to arteries, arterioles, and venules. The lower blood pressure in veins allows for the efficient return of blood to the heart despite the decreased pressure. Arteries have high blood pressure as they transport blood away from the heart at a rapid rate. Arterioles are smaller branches of arteries and contribute to resistance in the circulatory system, leading to a pressure drop. Venules are small blood vessels that collect blood from capillaries and gradually converge into veins, having slightly higher pressure than veins.
