Biology HESI A2 Practice Test

1. Cytosine and thymine are known as:

Correct answer: B

Rationale: Cytosine and thymine are known as pyrimidines because they have a single carbon ring structure. Purines, on the other hand, have a double-ring structure. Choice A ('Purines') is incorrect because purines have a double-ring structure, unlike cytosine and thymine. Choice C ('Both') is incorrect as it implies they are both purines and pyrimidines, which is not true. Choice D ('None of the above') is incorrect because cytosine and thymine are indeed pyrimidines.

2. What is the best title for the passage on bicycles?

Correct answer: C

Rationale: The correct answer is C: 'A Ride through the History of Bicycles.' This title best captures the passage's focus on the historical development and evolution of the bicycle from its invention to its modern form. Choice A, 'Bicycles Are Better,' is too general and doesn't encompass the historical aspect discussed in the passage. Choice B, 'Cycle Your Way to Fitness,' focuses solely on the fitness aspect of bicycles, ignoring the broader historical context. Choice D, 'The Popularity of Bicycles,' touches on one aspect but does not encompass the comprehensive historical journey presented in the passage.

3. How many meters are in 3000 millimeters?

Correct answer: A

Rationale: 1 meter is equal to 1000 millimeters. Therefore, to convert 3000 millimeters to meters, we divide by 1000. 3000 millimeters / 1000 = 3 meters. Choice A, '3 meters,' is the correct answer. Choice B, '30 meters,' is incorrect because it represents a miscalculation of multiplying instead of dividing. Choice C, '0.3 meters,' is incorrect as it is the result of a decimal error. Choice D, '300 meters,' is incorrect as it is a result of not converting millimeters to meters correctly.

4. What word is best to substitute for the underlined words in the following sentence? Francesca, Bill, and I enjoy using the hospital pool.

Correct answer: B

Rationale: The sentence is written in the first-person point of view, so the appropriate pronoun to use as a substitute for 'Francesca, Bill, and I' would be 'we.' This choice maintains the correct subject-verb agreement and ensures consistency in the sentence structure by keeping the pronoun in the nominative case. Choice A, 'They,' is incorrect as it changes the subject of the sentence, leading to a lack of agreement between the pronoun and the verb. Choices C and D, 'Them' and 'Us,' are both objective pronouns and do not fit the role of the subject in this sentence.

5. Convert 3/8 to a decimal.

Correct answer: D

Rationale: To convert 3/8 to a decimal, divide 3 by 8: 3 รท 8 = 0.375. The correct answer is 0.375. Choice A (0.25), Choice B (0.25), and Choice C (0.3) are incorrect because they do not represent the equivalent decimal value of 3/8.
