HESI A2 Quizlet Math

1. How many liters are in 5000 milliliters?

Correct answer: A

Rationale: To convert milliliters to liters, you divide by 1000 since 1000 milliliters make up 1 liter. In this case, 5000 milliliters divided by 1000 milliliters per liter equals 5 liters (5000 mL ÷ 1000 mL/L = 5 L). Therefore, the correct answer is A: 5 liters. Choice B, 4 liters, is incorrect because 5000 milliliters is equivalent to 5 liters, not 4. Choice C, 6 liters, is incorrect as it is not the accurate conversion from milliliters to liters in this case. Choice D, 5.5 liters, is incorrect as it does not reflect the correct conversion of 5000 milliliters to liters, which is 5 liters.

2. Which organelle is the site of photosynthesis in plant cells?

Correct answer: B

Rationale: The correct answer is B: Chloroplasts. Chloroplasts are responsible for conducting photosynthesis in plant cells. They contain chlorophyll, a pigment that captures light energy and converts it into chemical energy through the process of photosynthesis. Mitochondria (choice A) are known as the powerhouse of the cell and are involved in cellular respiration, not photosynthesis. Ribosomes (choice C) are responsible for protein synthesis. The endoplasmic reticulum (choice D) is involved in protein and lipid synthesis and transport within the cell, not photosynthesis.

3. What is the author’s primary purpose in writing this essay?

Correct answer: A

Rationale: The author’s enthusiastic and supportive tone toward yoga—stating that it is an exercise that "everyone should try"—indicates a clear intent to persuade the audience about the benefits of yoga. This aligns with choice A, as the primary purpose of the essay is to promote yoga as a valuable practice

4. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.

Correct answer: A

Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.

5. Which of the following is the best example of a hypothesis?

Correct answer: D

Rationale: Option D is the best example of a hypothesis because it presents a clear cause-and-effect relationship that can be tested through experimentation. It follows the format of 'If [cause], then [effect]' which is characteristic of a hypothesis in scientific research. The statement is specific, testable, and does not rely on personal opinions or biases, making it a strong and valid hypothesis. Choices A, B, and C do not follow the structure of a hypothesis as they lack the cause-and-effect relationship that can be tested through experimentation. They are more like statements or opinions rather than hypotheses.
