1. What is a major difference in the way baroreceptors and chemoreceptors work from the way the kidneys work?
- A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume.
- B. Baroreceptors and chemoreceptors both work to help maintain blood volume, whereas the kidneys take care of salts, water, and waste removal.
- C. Baroreceptors and chemoreceptors must work together to control blood pressure, whereas the kidneys work with the adrenal cortex.
- D. Baroreceptors and chemoreceptors are both located near the adrenal cortex, whereas the kidneys are located near the heart.
Correct answer: A
Rationale: The correct answer is A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume. Baroreceptors and chemoreceptors are responsible for monitoring blood pressure by sensing changes in pressure, oxygen levels, carbon dioxide levels, and pH within the arteries. They send out impulses to raise or lower blood pressure accordingly. On the other hand, the kidneys play a crucial role in regulating blood volume by absorbing salts and water and removing waste products. This key difference highlights that while baroreceptors and chemoreceptors are involved in monitoring and regulating blood pressure, the kidneys primarily focus on controlling blood volume. Choice B is incorrect because it inaccurately states that baroreceptors and chemoreceptors help maintain blood volume, which is not their primary function. Choice C is incorrect as it provides an inaccurate comparison between the roles of baroreceptors, chemoreceptors, and the kidneys. Choice D is incorrect as it wrongly associates the location of baroreceptors and chemoreceptors with the adrenal cortex, which is not accurate.
2. Based on this passage, what can the reader infer about the advice physicians will give their pregnant patients about coffee consumption?
- A. Almost all of them will advise women to stop drinking any caffeine until after the baby is born.
- B. The majority will ignore the study altogether and continue to advise caffeine in moderation as before.
- C. All of them will demand additional research be done before they change what they tell their patients.
- D. Some will continue to make their normal recommendations about caffeine, while others will be more cautious than before.
Correct answer: D
Rationale: The passage implies that there is variability in physician responses to the study about caffeine consumption. Some doctors may continue their standard recommendations, while others might advise more caution based on the new evidence. Therefore, option D reflects this variability in professional opinions and is the correct inference.
3. Which of the following statements is an opinion related to MRSA?
- A. Hand-washing stations are one means of combating MRSA infection.
- B. Not all Staphylococcus bacteria are resistant to antibiotics.
- C. Hospitals in the United States should quickly adopt the use of new germ-fighting textiles.
- D. MRSA infection kills more people in the United States than does HIV/AIDS.
Correct answer: C
Rationale: The correct answer is C because it is an opinion rather than a verifiable fact. The statement suggests a recommendation for hospitals to adopt new germ-fighting textiles swiftly, which is a subjective viewpoint and not objectively measurable. Choices A and B are factual statements regarding combating MRSA infection and antibiotic resistance, respectively. Choice D provides a comparison of MRSA infection with HIV/AIDS, which is a factual statement based on statistical data. Therefore, C is the only choice that presents an opinion rather than a fact.
4. The passage mentions all of the following claims for the health benefits of super foods EXCEPT ___________.
- A. lowering cholesterol
- B. stabilizing insulin levels
- C. building muscle mass
- D. reducing blood pressure
Correct answer: C
Rationale: The passage discusses various health benefits of superfoods, such as lowering cholesterol, stabilizing insulin levels, and reducing blood pressure. However, it does not mention anything about building muscle mass, making C the correct choice as it identifies the claim that is not supported by the passage.
5. What is the author’s primary purpose in writing the essay about Sunny-Side Up?
- A. To persuade.
- B. To reflect.
- C. To entertain.
- D. To inform.
Correct answer: D
Rationale: The author's primary purpose is to inform readers about the benefits of sunlight, including its role in vitamin D synthesis and other health benefits. While the passage does advocate for sunlight exposure, the primary aim is to provide information rather than persuade or entertain, making D the most accurate choice.
