1. Warming up before exercise is important to help prevent
- A. Dehydration
- B. Muscle soreness
- C. Increased heart rate
- D. Low blood sugar
Correct answer: B
Rationale: The correct answer is B: 'Muscle soreness.' Warming up before exercise is crucial as it helps increase blood flow to the muscles, warming them up and making them more flexible. This can help reduce the risk of muscle soreness and injury during and after exercise. Dehydration (A) is more related to maintaining proper fluid balance through hydration. Increased heart rate (C) is a normal response to exercise and can be beneficial. Low blood sugar (D) is more of a concern for individuals with conditions like diabetes. Therefore, the most immediate benefit of warming up is to prevent muscle soreness.
2. Which of the following units is equivalent to a joule?
- A. Newton-meter (N·m)
- B. Watt (W)
- C. Kilogram (kg)
- D. Ampere (A)
Correct answer: a
Rationale: A joule, as a unit of energy, is equivalent to a newton-meter in terms of work or energy.
3. Which blood vessels are responsible for carrying oxygenated blood away from the heart to the rest of the body?
- A. Veins
- B. Arteries
- C. Capillaries
- D. Venules
Correct answer: B
Rationale: The correct answer is B: Arteries. Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick and elastic walls to withstand the high pressure generated by the pumping action of the heart. Veins, on the other hand, carry deoxygenated blood back to the heart, while capillaries are tiny blood vessels where the exchange of oxygen and nutrients occurs. Venules are small veins that collect blood from capillaries and transport it to larger veins. Therefore, arteries are specifically designed to transport oxygenated blood away from the heart, making them the correct choice in this question.
4. In the phrase "a drop in the bucket," "bucket" represents:
- A. A literal container
- B. A large quantity
- C. A specific goal
- D. An obstacle
Correct answer: B
Rationale: The phrase signifies that something is insignificant compared to a much larger amount.
5. Which word is most closely associated with the adjective "ambiguous"?
- A. Precise
- B. Vague
- C. Definite
- D. Straightforward
Correct answer: B
Rationale: "Ambiguous" implies uncertainty or multiple interpretations, making "vague" its closest synonym.
6. What is the stage of mitosis during which the nuclear envelope reforms?
- A. Prophase
- B. Metaphase
- C. Telophase
- D. Cytokinesis
Correct answer: C
Rationale: Rationale: - Prophase is the stage of mitosis where the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. - Metaphase is the stage where the chromosomes line up along the metaphase plate in the middle of the cell. - Telophase is the stage where the nuclear envelope reforms around the separated sister chromatids at opposite poles of the cell. - Cytokinesis is the final stage of cell division where the cytoplasm divides to form two daughter cells, but it is not directly related to the reformation of the nuclear envelope.
