Quizlet Vocabulary HESI A2

1. It seems like the sun _____ on Saturday.

Correct answer: B

Rationale: The correct answer is 'never shone' as the sentence is discussing a past event (Saturday). 'Never shone' is the correct past tense form to describe the sun not shining on a specific day in the past. Choices A, C, and D are incorrect because they do not provide the appropriate past tense form needed in this context. 'Never shines' is present tense, 'rarely shines' implies occasional shining, and 'sometimes shines' suggests occasional shining as well, none of which accurately convey the past event of the sun not shining on Saturday.

2. In a phospholipid molecule, the head:

Correct answer: D

Rationale: The head of a phospholipid is hydrophilic (water-loving) and is located on the outer side of the lipid bilayer, interacting with water molecules. This arrangement positions the hydrophobic tails inward, away from water. Therefore, the correct answer is D. Choice A is incorrect because the head is hydrophilic, not hydrophobic. Choice B is incorrect as the head is on the outer side, not the inner side of the layer.

3. The abbreviation HPV on a medical form refers to a particular ___________.

Correct answer: B

Rationale: The abbreviation HPV stands for Human Papillomavirus, which is a viral infection commonly transmitted through sexual contact. It is known to cause genital warts and various types of cancers, including cervical cancer. Choice A is incorrect because HPV is not related to a blood condition. Choice C is incorrect because HPV does not refer to heart rate. Choice D is incorrect as HPV is not a therapy but rather a virus.

4. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both. Which of the following represents the LCM of 14 and 21?

Correct answer: C

Rationale: Rationale: To find the least common multiple (LCM) of 14 and 21, we need to determine the smallest number that is a multiple of both 14 and 21. First, list the multiples of 14: 14, 28, 42, 56, 70, 84, ... Next, list the multiples of 21: 21, 42, 63, 84, ... The smallest number that appears in both lists is 42. Therefore, the LCM of 14 and 21 is 42.

5. Which organelle is involved in the synthesis of proteins?

Correct answer: B

Rationale: Ribosomes are the organelles involved in the synthesis of proteins. They are the cellular machinery responsible for translating mRNA into proteins, making them essential for cell function and structure. The other organelles listed, such as the Endoplasmic Reticulum, Lysosomes, and Vacuoles, have different functions unrelated to protein synthesis. The Endoplasmic Reticulum plays a role in protein processing and transport, Lysosomes are involved in digestion and waste removal, and Vacuoles are responsible for storage and maintaining cell turgor pressure.
