1. Eric buys 5 1/2 pounds of apples each week for four weeks. How many total pounds does he buy?

• A. 22 pounds
• B. 20 pounds
• C. 18 pounds
• D. 24 pounds

Correct answer: A

Rationale: To find the total pounds of apples Eric buys, you need to multiply the pounds of apples bought each week (5 1/2 pounds) by the number of weeks (4 weeks). When you multiply 5 1/2 by 4, you get 22 pounds. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not accurately calculate the total pounds purchased over the four weeks.

2. Which of the following glands helps regulate calcium levels?

• A. Osteotoid gland
• B. Pineal gland
• C. Parathyroid glands
• D. Thymus gland

Correct answer: C

Rationale: The correct answer is C: Parathyroid glands. The parathyroid glands are responsible for regulating calcium levels in the body. They produce parathyroid hormone (PTH), which helps control calcium levels in the blood by acting on the bones, kidneys, and intestines. The other options, such as the osteotoid gland, pineal gland, and thymus gland, do not play a significant role in calcium regulation. The osteotoid gland is a fictitious term, the pineal gland is involved in regulating sleep-wake cycles and producing melatonin, and the thymus gland is part of the immune system and plays a role in T-cell maturation.

3. What is the noun phrase in the following sentence? Charlotte's new German shepherd puppy is energetic.

• A. Puppy
• B. Charlotte
• C. German shepherd puppy
• D. Charlotte's new German shepherd puppy

Correct answer: D

Rationale: The correct answer is 'Charlotte's new German shepherd puppy.' A noun phrase consists of a noun and any modifiers that go along with it. In this sentence, 'Charlotte's new German shepherd puppy' is a noun phrase because it includes the noun 'puppy' along with the modifiers 'Charlotte's,' 'new,' and 'German shepherd.' 'Puppy' alone (choice A) is not the complete noun phrase in this context as it lacks the modifiers. 'Charlotte' (choice B) is just a single noun and does not include the full descriptive phrase. 'German shepherd puppy' (choice C) is also not the complete noun phrase as it is missing the possessive 'Charlotte's' and 'new.' Therefore, the most appropriate noun phrase in the sentence is 'Charlotte's new German shepherd puppy.'

4. The function of synergists can best be described as which of the following? I. They assist primary movers in completing the specific movement II. They stabilize the point of origin and provide extra pull near the insertion III. They help prevent unwanted movement at a joint

• A. I, II
• B. I, III
• C. II, III
• D. All of the above

Correct answer: A

Rationale: Synergists are muscles that assist the primary movers (agonists) in completing specific movements (I). Additionally, they stabilize the point of origin and provide extra pull near the insertion, aiding in movement efficiency (II). While synergists may contribute to stability, their primary role is to assist in movement rather than prevent unwanted movement at a joint; hence, options I and II offer the most accurate descriptions of their function. Choice B is incorrect because synergists do not primarily help prevent unwanted movement at a joint (III). Choice C is incorrect as it combines stabilization of the point of origin and preventing unwanted movement, which is not the primary function of synergists.

5. What is the term for the process of separating the components of a solution based on their different rates of movement through a medium?

• A. Filtration
• B. Distillation
• C. Chromatography
• D. Precipitation

Correct answer: C

Rationale: Chromatography is the correct term for the process of separating the components of a solution based on their different rates of movement through a medium. In chromatography, the components move at different speeds due to their interactions with the medium, causing separation. Filtration involves using a barrier to separate solid particles from a liquid. Distillation separates components based on differences in boiling points to collect the vapor of the more volatile component. Precipitation refers to the formation of a solid from a solution by a chemical reaction or change in conditions.
