1. What is the term for the reaction between an acid and a base to produce water and a salt?

• A. Combustion
• B. Neutralization
• C. Oxidation
• D. Decomposition

Correct answer: b

Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.

2. Which vitamin is essential for collagen production, a key component of connective tissues?

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

Correct answer: B

Rationale: The correct answer is B: Vitamin C. Vitamin C is essential for collagen production, which is a key component of connective tissues. Collagen is a protein that provides structure and strength to various tissues in the body, including skin, bones, and tendons. Vitamin C plays a crucial role in the synthesis of collagen by acting as a cofactor for enzymes involved in collagen formation. Deficiency in Vitamin C can lead to impaired collagen production, resulting in weakened connective tissues and potential health issues like scurvy. While Vitamin A, D, and E are important for various bodily functions, Vitamin C specifically stands out for its vital role in collagen synthesis.

3. Which word best describes the relationship between population growth and smart cities in the passage?

• A. Cause and effect
• B. Analogy
• C. Contrast
• D. Similarity

Correct answer: A

Rationale: The passage identifies rapid population growth as a challenge that smart cities are proposed to address, establishing a causal connection.

4. A car brakes to a stop on a level road. Which of the following forces does NOT do work on the car?

• A. The braking force applied by the wheels
• B. The normal force from the road
• C. The gravitational force on the car
• D. The friction force between the tires and the road

Correct answer: B

Rationale: While the other forces do work by changing the car's motion or energy, the normal force acts perpendicular to the motion and doesn't contribute to the car's stopping.

5. During inhalation, which muscle contracts to increase the volume of the thoracic cavity, allowing air to flow into the lungs?

• A. Diaphragm
• B. Intercostal muscles
• C. Abdominal muscles
• D. Pectoral muscles

Correct answer: A

Rationale: The correct answer is A: Diaphragm. During inhalation, the diaphragm contracts and moves downward, increasing the volume of the thoracic cavity. This action creates a pressure difference between the lungs and the atmosphere, causing air to flow into the lungs. The intercostal muscles also play a role by expanding the ribcage, but the primary muscle responsible for increasing thoracic cavity volume during inhalation is the diaphragm. Abdominal muscles are involved in exhalation by contracting to push the diaphragm up, reducing thoracic cavity volume. Pectoral muscles are located in the chest and are not directly involved in the breathing process.

6. Tissues are groups of cells with similar:

• A. Appearance only
• B. Function and structure
• C. Location only
• D. Age only

Correct answer: B

Rationale: The correct answer is B: 'Function and structure.' Tissues are groups of cells that work together to perform a specific function in the body. These cells have both similar functions, such as carrying out a specific task like contracting in muscle tissue, and similar structures, such as having similar shapes or types of organelles. This allows them to work together efficiently and effectively. Choices A, C, and D are incorrect because tissues are defined by more than just appearance, location, or age; they are primarily characterized by their shared function and structure.
