1. Which of the following sentences demonstrates the correct use of an apostrophe?

• A. Lyle works for the courthouse, and among his responsibilities is getting the jurors meal’s.
• B. Lyle works for the courthouse, and among his responsibilities is getting the juror’s meals.
• C. Lyle works for the courthouse, and among his responsibilities is getting the jurors’ meals.
• D. Lyle works for the courthouse, and among his responsibilities is getting the jurors meals’.

Correct answer: C

Rationale: The apostrophe is correctly placed in this sentence to show possession by multiple jurors.

2. Which vitamin plays a vital role in muscle function and helps prevent muscle weakness and fatigue?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: Vitamin D is the correct answer as it plays a crucial role in muscle function by helping prevent muscle weakness and fatigue. It is essential for maintaining muscle strength and function, as well as supporting overall bone health. Vitamin D deficiency can lead to muscle weakness and fatigue, emphasizing its significance for muscle health. Vitamin A does not directly impact muscle function in the same way as Vitamin D. Although Vitamin B12 is important for neurological function and red blood cell production, it is not primarily known for its role in muscle function. Vitamin E is more commonly associated with its antioxidant properties and its role in protecting cells from damage, but it is not specifically linked to muscle function and preventing muscle weakness and fatigue.

3. What term refers to the point of contact between a motor neuron and a muscle fiber, where communication occurs to initiate muscle contraction?

• A. Sarcomere
• B. Synapse
• C. Tendon
• D. Myofibril

Correct answer: B

Rationale: The correct answer is B, 'Synapse.' The synapse is the specific term that refers to the point of contact between a motor neuron and a muscle fiber, where communication occurs to initiate muscle contraction. At the synapse, neurotransmitters are released by the motor neuron, triggering the muscle fiber to contract. Choice A, 'Sarcomere,' is incorrect as a sarcomere is the basic unit of muscle contraction, not the point of contact between a motor neuron and a muscle fiber. Choice C, 'Tendon,' is incorrect as tendons are fibrous connective tissues that connect muscle to bone, not involved in neuronal communication. Choice D, 'Myofibril,' is incorrect as a myofibril is a structure within muscle fibers where muscle contractions occur, not the specific point of contact for communication between a motor neuron and a muscle fiber.

4. Which of the following suffixes denotes a state or quality?

• A. -ic
• B. -ness
• C. -ous
• D. -ful

Correct answer: B

Rationale: The suffix "-ness" indicates a state or quality, as seen in words like "happiness" (the state of being happy). Choice A, "-ic," typically denotes characteristics or qualities, such as in "heroic." Choice C, "-ous," often signifies the presence of a quality or relationship, like in "poisonous." Choice D, "-ful," usually means full of or characterized by, as in "beautiful." Therefore, the correct answer is B because it best fits the description of indicating a state or quality.

5. Which of the following correctly lists the four properties that all types of muscle tissue share?

• A. Contractile, excitable, elastic, extensible
• B. Contractile, voluntary, elastic, extensible
• C. Contractile, excitable, voluntary, extensible
• D. Contractile, excitable, elastic, voluntary

Correct answer: A

Rationale: The correct answer is A: 'Contractile, excitable, elastic, extensible.' All types of muscle tissue share these four properties. Muscle tissue can contract, respond to stimuli, stretch and return to its original shape (elastic), and extend or stretch (extensible). Choice B is incorrect because not all muscle tissues are voluntary (some are involuntary). Choice C is incorrect because not all muscle tissues are voluntary. Choice D is incorrect because not all muscle tissues are voluntary and lack the elastic property.
