Grammar HESI A2 Practice Test

1. Select the word or phrase that will make the sentence grammatically correct. The village is not very far _________ the railway station.

Correct answer: B

Rationale: The correct preposition to use in this sentence is 'from.' When referring to the distance between two locations, we use 'from' to indicate the starting point and 'to' to indicate the destination. In this case, the village is not very far from the railway station, showing the distance between the two places. Choice A ('to') is incorrect as it implies the village is far in the direction of the railway station. Choice C ('by') is incorrect as it suggests proximity rather than distance. Choice D ('next') is incorrect as it indicates the location of the village in relation to the railway station, not the distance between them.

2. If electrons are not shared equally in a covalent bond, the bond is what?

Correct answer: A

Rationale: A polar covalent bond occurs when electrons are shared unequally between atoms. In this type of bond, one atom has a stronger pull on the shared electrons, leading to a partial positive and partial negative charge distribution within the molecule. Choice B, non-polar, is incorrect because in non-polar covalent bonds, electrons are shared equally between atoms. Choice C, ionic, is incorrect as ionic bonds involve a transfer of electrons rather than sharing. Choice D, hydrogen, is incorrect as it does not describe the nature of a covalent bond.

3. What is the normal body temperature in °C?

Correct answer: B

Rationale: The normal body temperature for humans is 37°C. This temperature is considered average and is a standard reference point for assessing an individual's health status. It is essential for the body to maintain this temperature to ensure optimal functioning of various physiological processes. Choice A (36°C) is incorrect as it is slightly below the normal body temperature. Choice C (35°C) is also incorrect as it is significantly lower than the normal body temperature. Choice D (40°C) is incorrect as it is significantly higher than the normal body temperature and would indicate a fever or other health issue.

4. 72 chromosomes undergo meiosis. How many chromosomes will be in each gamete?

Correct answer: A

Rationale: During meiosis, the number of chromosomes is halved in each gamete. Since 72 chromosomes undergo meiosis, each gamete will contain half of that number, which is 36 chromosomes. Therefore, the correct answer is 18 chromosomes in each gamete. Choice B (36 chromosomes) is incorrect because it represents the total number of chromosomes that undergo meiosis, not the number in each gamete. Choice C (72 chromosomes) is incorrect as it represents the initial number of chromosomes, not the number in each gamete after meiosis. Choice D (144 chromosomes) is incorrect as it doubles the initial number of chromosomes, which is not the outcome of meiosis.

5. How many grams are in 4 kilograms?

Correct answer: A

Rationale: The correct answer is A: 4000 grams. To convert kilograms to grams, you need to multiply the number of kilograms by 1000 since there are 1000 grams in 1 kilogram. Therefore, 4 kilograms is equal to 4 x 1000 = 4000 grams. Choice B (3000 grams), C (4500 grams), and D (3500 grams) are incorrect as they do not correctly convert 4 kilograms into grams.
