Reading

1. The passage implies that achieving energy sustainability requires...

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

2. Which additional information would be MOST relevant to the topic of the passage?

Correct answer: B

Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.

3. Two cars with different masses collide head-on. Which car experiences a greater change in momentum?

Correct answer: B

Rationale: The car with the smaller mass. Although momentum is conserved in the collision, the change in momentum is inversely proportional to mass. Therefore, the car with the smaller mass will experience a larger relative change.

4. What protein complex controls the progression of mitosis through its activation and degradation?

Correct answer: B

Rationale: Rationale: A) Ribosome: Ribosomes are cellular organelles responsible for protein synthesis and are not directly involved in controlling the progression of mitosis. B) Cyclin-dependent kinase (CDK): CDKs are a family of protein kinases that regulate the cell cycle, including the progression of mitosis. CDK activity is controlled by cyclins, which bind to CDKs to activate them at specific points in the cell cycle. The activation and degradation of cyclins regulate the activity of CDKs, which in turn control the progression of mitosis. C) Centriole: Centrioles are involved in organizing the microtubules of the mitotic spindle but do not directly control the progression of mitosis. D) Microtubule: Microtubules are structural components of the cytoskeleton and are involved in various cellular processes, including mitosis, but they do not control

5. What is the scientific term for scar tissue?

Correct answer: B

Rationale: The correct answer is B: Fibrous connective tissue. Scar tissue is formed during the process of wound healing, where fibroblasts produce collagen fibers to repair damaged tissue. This results in the formation of fibrous connective tissue, which is different from epithelial tissue (A), cartilage (C), and adipose tissue (D). While epithelial tissue lines surfaces and organs, cartilage is a type of connective tissue found in joints, and adipose tissue is a type of connective tissue that stores energy in the form of fat. Scar tissue, on the other hand, is primarily composed of collagen fibers and is classified as fibrous connective tissue.

6. The speed of light in a vacuum is measured in units of:

Correct answer: A

Rationale: The correct answer is A: 'Meters per second.' The speed of light in a vacuum is a fundamental constant of nature and is approximately 299,792,458 meters per second. This speed is constant and does not vary based on the frequency or wavelength of light. Hertz (B) is a unit of frequency, Candela (C) is a unit of luminous intensity, and Newton (D) is a unit of force. Understanding the units used to measure the speed of light is important in physics and related fields to accurately describe the propagation of light in different mediums.
