1. Which of the following statements about the autonomic nervous system (ANS) is true?

• A. It controls involuntary functions
• B. It contains motor (efferent) neurons
• C. It contains sensory (afferent) neurons
• D. It contains both parasympathetic and sympathetic nerves

Correct answer: D

Rationale: The correct answer is D because the autonomic nervous system (ANS) is responsible for controlling involuntary functions and contains both parasympathetic and sympathetic nerves. Choices A and B are incorrect as they do not fully capture the role of the ANS. While the ANS does control involuntary functions, this is a broader concept than just the reflex arc. While the ANS does contain motor (efferent) neurons, it also includes sensory (afferent) neurons, which are not specifically mentioned in the question. Therefore, choice C is not fully accurate. Choice D provides the most accurate and comprehensive description of the autonomic nervous system by highlighting its components, the parasympathetic and sympathetic nerves, which work together to regulate various bodily functions.

2. She is a fierce competitor, and nothing is going to keep her from running that marathon despite a hamstring injury. Which of the following describes the grammar problem in the sentence above?

• A. Poor diction
• B. Ambiguous word choice
• C. Tense disagreement
• D. Inappropriate transition word choice

Correct answer: C

Rationale: The correct answer is C, tense disagreement. The sentence contains a tense disagreement between 'was' and 'is.' 'She is a fierce competitor' and 'nothing is going to keep her' are in the present tense, while 'was going to keep her' should also be in the present tense to maintain consistency. Choices A, B, and D are incorrect because the issue in the sentence is related to verb tense, not diction, word choice, or transition words.

3. Which part of the nervous system controls the 'fight or flight' response?

• A. Central nervous system
• B. Peripheral nervous system
• C. Autonomic nervous system
• D. Sympathetic nervous system

Correct answer: D

Rationale: The correct answer is the sympathetic nervous system. It controls the 'fight or flight' response by preparing the body for stressful situations. The central nervous system (Choice A) consists of the brain and spinal cord but does not directly control the 'fight or flight' response. The peripheral nervous system (Choice B) includes nerves outside the brain and spinal cord, while the autonomic nervous system (Choice C) regulates involuntary bodily functions but is not specific to the 'fight or flight' response.

4. Which of the following best explains the meaning of extraneous as it is used in the sentence? The report was filled with extraneous details that had nothing to do with the main findings of the study.

• A. sophisticated
• B. irrelevant
• C. diligent
• D. useful

Correct answer: B

Rationale: The word 'extraneous' means something that is irrelevant or unnecessary to the main topic at hand. In the given sentence, 'extraneous' is used to describe details that are not related to the main findings of the study, indicating that they are unnecessary and irrelevant. Therefore, 'irrelevant' is the correct explanation. Choices 'sophisticated,' 'diligent,' and 'useful' do not convey the concept of being unnecessary or unrelated, making them incorrect in the context of the sentence.

5. Where is the energy for most cellular processes produced?

• A. Nucleus
• B. Cytoplasm
• C. Mitochondria
• D. Ribosomes

Correct answer: C

Rationale: The correct answer is C: Mitochondria. The energy for most cellular processes is produced in the mitochondria through the process of cellular respiration. Mitochondria are often referred to as the powerhouse of the cell because they generate ATP, the energy currency of the cell. This process involves the breakdown of glucose molecules to produce ATP, which fuels various cellular activities. Choices A, B, and D are incorrect. The nucleus is responsible for storing genetic material and controlling cell activities, not energy production. The cytoplasm is where various cellular activities take place, but it is not the primary site for energy production. Ribosomes are involved in protein synthesis and do not generate energy for cellular processes.
