1. I truly believe that one cup of coffee a day is neither too much nor too little caffeine for me, but exactly the right amount. Which of the following words is misspelled in the sentence above?

• A. caffeine
• B. truly
• C. neither
• D. exactly

Correct answer: A

Rationale: The correct answer is A: 'caffeine.' The word 'caffeine' is spelled with only one 'e' after the 'f,' not 'caffiene.' 'Truly,' 'neither,' and 'exactly' are all spelled correctly in the sentence provided.

2. Which neurotransmitter is responsible for stimulating muscle contraction?

• A. Dopamine
• B. Acetylcholine
• C. Serotonin
• D. Norepinephrine

Correct answer: B

Rationale: Acetylcholine is the neurotransmitter responsible for stimulating muscle contraction at the neuromuscular junction. When an action potential reaches the end of a motor neuron, acetylcholine is released into the synaptic cleft and binds to receptors on the muscle cell membrane, leading to muscle contraction. Dopamine, serotonin, and norepinephrine are neurotransmitters that have different functions in the nervous system and are not directly involved in stimulating muscle contraction. Dopamine is involved in reward and pleasure pathways, serotonin regulates mood and behavior, and norepinephrine is involved in the 'fight or flight' response.

3. In the sentence, 'The receptionist explained that we would be the next to see the doctor,' which of the following is the complete predicate?

• A. explained that we would be the next to see the doctor
• B. next to see the doctor
• C. explained that we would be next
• D. see the doctor

Correct answer: A

Rationale: The complete predicate is 'explained that we would be the next to see the doctor.' In a sentence, the complete predicate includes the main verb (explained) and all the words that complete its meaning (that we would be the next to see the doctor). Choices B, C, and D do not constitute the complete predicate as they do not include the main verb 'explained' and all associated words that complete its meaning.

4. What does the following sentence most nearly mean? 'The preparatory instars of such insects are aquatic; the adult instar is aerial.'

• A. The volume of water is necessary for preparing the insect for transition rather than the volume of the air.
• B. The insect's body is shaped like a star in both water and air.
• C. The stage of preparation between molting occurs in water, while the final stage happens in the air.
• D. These insects first breathe in water through gills and then continue to use the same organs to breathe in the air.

Correct answer: C

Rationale: The sentence indicates that the insects undergo different stages of development, with the preparatory instars being aquatic and the adult instar being aerial. This highlights the adaptability of these insects to different environments. Choice A is incorrect as it focuses on the volume of water and air rather than the stages of development in different environments. Choice B is unrelated to the content of the sentence and does not capture the meaning accurately. Choice D is incorrect as it specifically mentions breathing through gills, which is not explicitly stated in the sentence. Therefore, choice C is the best interpretation of the sentence.

5. What is the role of the kidneys in the body?

• A. To regulate body temperature
• B. To filter waste from the blood
• C. To produce hormones
• D. To transport oxygen

Correct answer: B

Rationale: The correct answer is B: To filter waste from the blood. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain fluid balance and eliminate toxins from the body. Choice A is incorrect because regulating body temperature is primarily controlled by the skin and other mechanisms. Choice C is incorrect as hormone production is mainly attributed to other organs like the endocrine glands. Choice D is incorrect as the transportation of oxygen is primarily facilitated by the lungs and circulatory system, not the kidneys.
