Quizlet Vocabulary HESI A2

Correct Answer: B

Rationale: The correct answer is B: Movement of materials from high concentration to low concentration. Diffusion is a passive process where molecules move from areas of high concentration to areas of low concentration to achieve equilibrium. This process does not require energy input. In diffusion, molecules randomly move and spread out to reach a balanced distribution. Choice A is incorrect as it describes active transport, which involves movement from low to high concentration and requires energy. Choices C and D are unrelated to the definition of diffusion and do not involve the movement of materials based on concentration gradients.

Correct Answer: B

Rationale: The correct answer is B: Incurable. "Incorrigible" means unable to be corrected or reformed. The prefix "in-" indicates negation, so "incurable" is the opposite of "curable." Choices A, C, and D do not accurately capture the meaning of "incorrigible." Choice A suggests the opposite of the correct meaning, choice C is related to a different concept of persistence, and choice D implies a temporary condition, all of which are not synonymous with the term "incorrigible."

Correct Answer: A

Rationale: The correct answer is A: "was elected". This is because the verb "elected" is the appropriate past tense form to describe the action of becoming president through a formal voting process. It is grammatically correct to say "John Kennedy was elected President in 1960." Choice B: "became" is incorrect as it does not convey the specific process of being chosen through an election. Choice C: "was made" is incorrect as it implies that someone else appointed or designated John Kennedy as President, which is not the case in a democratic election. Choice D: "become" is incorrect as it is not the past tense form of the verb needed to complete the sentence properly.

Correct Answer: C

Rationale: The word "cease" means to stop or come to an end. In the given sentence, "The rain will cease at sundown," it indicates that the rain will stop. Therefore, choice C, "Stop," is the correct answer. Choices A, B, and D are incorrect because they do not convey the same meaning as "cease." A (Decrease) implies a reduction in amount, B (Begin) implies starting, and D (Increase) implies a growth or rise, which do not align with the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: Extremely changing. Labile refers to being easily altered or constantly shifting. This is the best fit as it captures the essence of the word. Choice B, suicidal, is unrelated to the meaning of labile. Choice C, rapidly changing, is similar but not as strong as "extremely changing." Choice D, with a high fever, is completely unrelated to the meaning of labile. Thus, A is the correct answer as it aligns most closely with the definition of labile.
