Biology HESI A2 Practice Test

1. How do animal cells divide?

Correct answer: A

Rationale: Animal cells divide through a contractile ring made of actin and myosin filaments. The ring contracts, pinching the cell membrane in the middle to form two daughter cells. Plant cells use a cell plate due to their rigid cell walls, making choices B and C incorrect. Choice D is incorrect as animal cells do use the contractile ring method for division.

2. If a runner runs 5 miles in 45 minutes, what is their average speed in miles per hour?

Correct answer: A

Rationale: To find the average speed, first, convert 45 minutes to hours (45/60 = 0.75 hours). Then, divide the distance by the time: 5 miles ÷ 0.75 hours = 6.67 mph. Choice A is correct because it accurately calculates the average speed based on the distance covered and time taken. Choice B is incorrect as it does not consider the time taken to cover the distance. Choice C is incorrect as it is higher than the calculated speed. Choice D is incorrect as it is higher and does not match the calculated average speed.

3. What does Constrict mean?

Correct answer: B

Rationale: The correct answer is B: 'To draw together.' Constrict means to narrow or squeeze, making something smaller or tighter. This is the opposite of expanding (choice A), freezing (choice C), and dissolving (choice D), which do not involve the action of drawing together or becoming smaller.

4. Calculate the product of (99)(0.56) =

Correct answer: C

Rationale: To find the product of 99 and 0.56, multiply the two numbers: 99 x 0.56 = 55.44. Therefore, the correct answer is 55.44.

5. What word is best to substitute for the underlined words in the following sentence? The doctor and I went over the doctor’s and my notes.

Correct answer: C

Rationale: The word 'our' is the best substitute for the underlined words 'the doctor’s and my' in the sentence. Using 'our' indicates joint possession, making the sentence more concise and natural. Choice A, 'his', is singular possessive and does not reflect the joint ownership implied by the sentence. Choice B, 'their', is plural possessive and does not align with the singular subjects 'the doctor and I'. Choice D, 'mine', is possessive for the first person singular pronoun and does not convey the shared ownership of the notes by both individuals.
