physics

1. Which law of motion explains the behavior of rockets in space?

Correct answer: c

Rationale: Newton's Third Law of motion explains that for every action, there is an equal and opposite reaction, which propels rockets in space.

2. Dietary fiber, although not fully digested by the body, plays a crucial role in digestion. What is one of the main benefits of consuming sufficient dietary fiber?

Correct answer: C

Rationale: Consuming sufficient dietary fiber promotes satiety and gut health. Fiber adds bulk to the diet, which helps you feel full and satisfied after meals, reducing overeating. Additionally, fiber helps regulate bowel movements by promoting healthy digestion and preventing constipation. It also feeds beneficial gut bacteria, supporting a healthy gut microbiome. While fiber does not provide energy like carbohydrates, it is essential for overall digestive health and can help prevent various chronic diseases.

3. What is the process of cells becoming specialized to perform specific functions called?

Correct answer: B

Rationale: Rationale: A) Cell division refers to the process by which a parent cell divides into two or more daughter cells. B) Cell differentiation is the process by which cells become specialized to perform specific functions. During differentiation, cells acquire specific structures and functions that allow them to carry out particular roles in the body. C) Cell growth is the process by which cells increase in size and number. D) Cell regeneration is the process by which new cells are produced to replace damaged or lost cells in an organism. In this context, the process of cells becoming specialized to perform specific functions is best described as cell differentiation.

4. Which of the following phrases is grammatically correct and uses parallel structure?

Correct answer: B

Rationale: Option B uses the gerund (-ing) form for all three hobbies, achieving parallel structure.

5. When a muscle shortens and generates force, this is called a:

Correct answer: A

Rationale: The correct answer is A: Contraction. When a muscle shortens and generates force, it is undergoing a contraction. During a contraction, the muscle fibers are actively pulling on the tendons, causing movement at a joint. This process requires energy and coordination between muscle fibers to contract simultaneously. In contrast, relaxation (option B) is when the muscle fibers return to their resting length and stop generating force. Extension (option C) refers to the movement that increases the angle at a joint, typically involving the lengthening of muscles. Atrophy (option D) is the wasting away or decrease in size of muscle tissue due to disuse or disease, not the active shortening and force generation of a muscle during a contraction.

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

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.
