1. What is the law of conservation of energy?

• A. Energy cannot be created, only destroyed
• B. Energy can be created but not destroyed
• C. Energy can neither be created nor destroyed, only transformed from one form to another
• D. Energy is always created in any process

Correct answer:

Rationale: According to the law of conservation of energy, the total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.

2. Which phrase best describes the tone of the passage?

• A. Humorous and lighthearted
• B. Suspenseful and mysterious
• C. Objective and informative
• D. Critical and judgmental

Correct answer: C

Rationale: The passage presents factual information without injecting personal opinions or emotions. A, B, and D suggest tones not present in the passage's neutral delivery.

3. The human body's command center, integrating sensory information and coordinating movement and vital functions, is the:

• A. Lungs
• B. Brain
• C. Kidneys
• D. Stomach

Correct answer: B

Rationale: The correct answer is B: Brain. The brain serves as the command center of the human body, receiving sensory information from various parts of the body and coordinating responses. It is responsible for controlling movement, regulating vital functions such as breathing and heart rate, and processing thoughts and emotions. The lungs (A), kidneys (C), and stomach (D) each have specific functions within the body, but they do not serve as the central command center like the brain does. Therefore, the brain is the correct answer to this question.

4. Identify the conjunction in the following sentence: He went to the store, but they were already closed.

• A. went
• B. to
• C. but
• D. they

Correct answer: C

Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.

5. What is the term for a solution that has a lower concentration of solute compared to another solution?

• A. Saturated solution
• B. Unsaturated solution
• C. Dilute solution
• D. Concentrated solution

Correct answer: C

Rationale: A dilute solution has a lower concentration of solute compared to another solution. The other choices do not accurately describe a dilute solution.

6. The body's first line of defense against pathogens is the innate immune system. Which of the following is NOT a component of the innate immune system?

• A. Physical barriers like skin and mucous membranes
• B. Phagocytes that engulf and destroy pathogens
• C. Inflammatory response to isolate and contain infection
• D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The innate immune system is the body's first line of defense against pathogens and includes physical barriers like skin and mucous membranes, phagocytes that engulf and destroy pathogens, and the inflammatory response to isolate and contain infection. However, the production of antibodies specific to a particular pathogen is a function of the adaptive immune system, not the innate immune system. The innate immune system provides immediate, nonspecific defenses, while the adaptive immune system generates specific responses to target pathogens. Therefore, option D is NOT a component of the innate immune system, making it the correct answer in this question.
