physics

1. What is the law of conservation of energy?

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 of the following is the primary function of the cell membrane?

Correct answer: B

Rationale: Rationale: The cell membrane, also known as the plasma membrane, plays a crucial role in regulating the movement of substances in and out of the cell. It is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This function is essential for maintaining the internal environment of the cell and ensuring that necessary nutrients can enter the cell while waste products and other substances can exit. While the cell membrane does provide some structural support for the cell, its primary function is to control the transport of substances. The synthesis of proteins and lipids primarily occurs in other cellular organelles such as the endoplasmic reticulum and Golgi apparatus, while storing genetic material is the function of the nucleus.

3. Muscle soreness after exercise is often caused by microscopic tears in muscle fibers. This is called

Correct answer: C

Rationale: Muscle soreness after exercise is commonly caused by microscopic tears in muscle fibers, leading to a condition known as Delayed Onset Muscle Soreness (DOMS). Atrophy refers to the shrinking of muscle due to inactivity or lack of use, which is not the cause of muscle soreness after exercise. Hypertrophy is the increase in muscle size through exercise, not related to muscle soreness. Spasm is a sudden, involuntary muscle contraction unrelated to the micro-tears that cause muscle soreness. Therefore, the correct answer is C, DOMS, as it specifically addresses the micro-tears in muscle fibers that result in post-exercise soreness.

4. What literary device is used in the line "The sea whispered secrets to the shore"?

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.

5. 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.

6. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?

Correct answer: D

Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.
