HESI A2 Vocabulary Practice Test

1. What does Endogenous mean?

Correct answer: B

Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.

2. If a helicopter flies at about 80 mph, how long will it take to travel 140 miles?

Correct answer: D

Rationale: To calculate the time it takes to travel a certain distance, we can use the formula Time = Distance / Speed. In this case, the helicopter is flying at 80 mph and needs to travel 140 miles. Therefore, Time = 140 miles / 80 mph = 1.75 hours or 1 hour and 45 minutes. So, the correct answer is D. 1 hour 45 minutes. Choices A, B, and C are incorrect as they do not represent the accurate time it takes for the helicopter to cover the 140-mile distance at 80 mph.

3. Choose the meaning of the word 'supplement' in the following sentence: 'Calcium pills may be used to supplement your diet.'

Correct answer: B

Rationale: In the context of the sentence, the word 'supplement' is used to mean adding something extra to enhance or complete the diet. Therefore, the meaning of the word is 'add to.' Choice A ('Replace') is incorrect because 'supplement' does not mean to substitute or exchange. Choice C ('Reflect') is incorrect because 'supplement' does not mean to mirror or show. Choice D ('Parallel') is incorrect because 'supplement' does not mean to correspond or be similar in a particular way.

4. Which of the following is true of heterozygous traits?

Correct answer: D

Rationale: Heterozygous traits are denoted by having two different alleles for a particular gene, represented as Aa. This means that they are not haploid (A), not denoted AA (B), and not denoted aa (C). Therefore, the correct answer is D, as heterozygous traits are represented as Aa.

5. What is the first step in the conversion of glucose to pyruvate?

Correct answer: A

Rationale: The correct answer is Glycolysis. Glycolysis is the initial step in the conversion of glucose to pyruvate. During glycolysis, glucose is broken down into pyruvate through a series of enzymatic reactions. Choice B, the Krebs cycle, occurs after glycolysis in aerobic cellular respiration. Choice C, the Electron transport chain, is the final step in aerobic respiration where the majority of ATP is produced. Choice D, Aerobic respiration, is a broader term that encompasses glycolysis, the Krebs cycle, and the electron transport chain, but it is not the specific first step in the conversion of glucose to pyruvate.
