1. Skeletal muscles are attached to bones by tough connective tissues called

• A. Ligaments
• B. Tendons
• C. Cartilage
• D. Fascia

Correct answer: B

Rationale: Skeletal muscles are attached to bones by tough connective tissues called tendons. Tendons are strong, fibrous cords that connect muscles to bones, allowing for movement and stability in the body. Ligaments (option A) connect bones to other bones, not muscles to bones. Cartilage (option C) is firm and flexible connective tissue found in various parts of the body, but it does not attach muscles to bones. Fascia (option D) is a connective tissue that surrounds muscles, providing support and protection, but it does not directly attach muscles to bones.

2. What principle explains the relationship between pressure, volume, and temperature for ideal gases?

• A. Law of conservation of energy
• B. Newton's laws of motion
• C. Ideal gas law
• D. Archimedes' principle

Correct answer: C

Rationale: The correct answer is the Ideal Gas Law (Choice C). The ideal gas law, PV = nRT, describes the relationship between pressure (P), volume (V), temperature (T), and the number of moles of gas (n) for an ideal gas. It states that the product of pressure and volume is directly proportional to the absolute temperature of the gas when the number of moles is held constant. This law is a fundamental principle in understanding the behavior of ideal gases. Choices A, B, and D are incorrect. The Law of conservation of energy (Choice A) pertains to the principle that energy cannot be created or destroyed; Newton's laws of motion (Choice B) describe the relationship between the motion of an object and the forces acting on it; Archimedes' principle (Choice D) deals with the buoyant force exerted on an object immersed in a fluid. These principles are not directly related to the relationship between pressure, volume, and temperature for ideal gases.

3. Which of the following items is NOT a primary function of a healthy immune system?

• A. The immune system helps the body avoid infections.
• B. The immune system detects infections.
• C. The immune system eliminates infections.
• D. The immune system creates infections.

Correct answer: D

Rationale: The correct answer is D. The primary functions of a healthy immune system do not involve creating infections. A healthy immune system helps the body avoid infections by providing defense mechanisms, detects infections by recognizing harmful pathogens, and eliminates infections by attacking and clearing out pathogens. Creating infections goes against the protective role of the immune system and is not a function it performs. Therefore, choices A, B, and C are correct functions of a healthy immune system, while choice D is incorrect.

4. Which of the following sentences is a fragment?

• A. Went to the store yesterday.
• B. She went to the store yesterday.
• C. Yesterday, she went to the store.
• D. She went to the store.

Correct answer: A

Rationale: The correct answer is A - 'Went to the store yesterday.' This sentence is a fragment because it lacks a subject. A complete sentence should have both a subject and a verb. Choice B, C, and D are all complete sentences as they have both a subject ('She') and a verb ('went'). Therefore, they are not fragments.

5. Which of the following statements would require a citation?

• A. The rate of increase in gasoline prices is unprecedented.
• B. I saw on the news that gas prices are increasing.
• C. Economic Times reported that gas prices are up 11% from last month.
• D. My friend and I were shocked by how much gas cost when we filled up yesterday.

Correct answer: C

Rationale: The correct answer is C because when referencing a specific report, publication, or statistic like 'gas prices are up 11% from last month,' a citation is necessary to provide credibility and allow readers to verify the information. Choice A is a general statement about gasoline prices and does not require a citation as it is commonly known information. Choice B is a personal observation and not a direct reference to a specific source that would require a citation. Choice D is an anecdotal experience and does not present verifiable data that necessitates a citation.
