1. What are the two catabolic pathways that lead to cellular energy production?

• A. Fermentation and internal respiration
• B. Fermentation and external respiration
• C. Fermentation and cellular respiration
• D. Fermentation and anaerobic respiration

Correct answer: C

Rationale: The correct answer is 'Fermentation and cellular respiration.' Fermentation is an anaerobic catabolic process that occurs in the absence of oxygen, producing limited amounts of ATP. Cellular respiration, on the other hand, is the aerobic catabolic pathway that occurs in the presence of oxygen and is the most efficient way of producing ATP. Choices A, B, and D are incorrect because internal respiration, external respiration, and anaerobic respiration are not the correct pathways leading to cellular energy production.

2. Which of the following substances has the highest density?

• A. Mist
• B. Water
• C. Steam
• D. Ice

Correct answer: B

Rationale: Water has the highest density among the options provided. Density is a measure of mass per unit volume. In this case, water in its liquid form is denser than mist, steam, and ice. Ice has a lower density than water because its crystalline structure causes it to be less dense. Mist and steam are forms of water vapor, which are much less dense than liquid water. Therefore, the correct answer is water (choice B).

3. In a scenario where a transverse wave transports energy from north to south, in what direction do the particles in the medium move?

• A. Only north to south
• B. Both northward and southward
• C. Only east to west
• D. Both eastward and westward

Correct answer: B

Rationale: In a transverse wave, particles of the medium move perpendicular to the direction of energy transport. When the wave transports energy from north to south, the particles in the medium oscillate up and down, causing them to move both northward and southward. Choice A is incorrect because the particles move in both directions, not only from north to south. Choices C and D are incorrect as they mention directions that are not relevant to the scenario described in the question.

4. What does Dilute mean?

• A. To concentrate
• B. To make a liquid less concentrated
• C. To solidify
• D. To evaporate

Correct answer: B

Rationale: The correct definition of dilute is to make a liquid less concentrated. When a substance is diluted, it means it has been mixed with another substance to reduce its strength or concentration. Option A, 'To concentrate,' is the opposite of dilute. Option C, 'To solidify,' means to make or become hard or solid, which is unrelated to diluting a liquid. Option D, 'To evaporate,' means to change from a liquid to a vapor, also unrelated to diluting a liquid. Therefore, the correct answer is B.

5. Which statement would not be inferred by the reader in the passage about Hypertension?

• A. Maintaining a healthy weight may help to prevent hypertension.
• B. There is presently no reliable treatment for hypertension.
• C. Your ethnicity may contribute to your risk for hypertension.
• D. A 60-year-old is more likely to have hypertension than a teenager is.

Correct answer: B

Rationale: The correct answer is B. The passage clearly states that there are treatments for hypertension, so the statement that there is presently no reliable treatment for hypertension cannot be inferred from the text. Choice A can be inferred from paragraph 3 where it mentions losing weight to decrease blood pressure. Choice C can be inferred from paragraph 1 where it states that African Americans are more likely to have hypertension. Choice D can be inferred from paragraph 2 where it explains that older people are most often diagnosed with hypertension due to changes in blood vessels as they age.
