1. Which property of matter remains constant regardless of changes in gravity?
- A. Mass
- B. Weight
- C. Volume
- D. Density
Correct answer: A
Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in gravity. Weight, on the other hand, is the force of gravity acting on an object's mass and can vary depending on the strength of gravity. Volume is the amount of space an object occupies, which can change depending on the environment, and density is the mass of an object per unit volume, which can also change with variations in gravity.
2. The passage implies that achieving energy sustainability requires...
- A. solely relying on renewable energy sources for electricity generation.
- B. a combination of advancements in renewable energy production and management technologies.
- C. prioritizing economic benefits over environmental concerns when making energy choices.
- D. focusing solely on reducing energy consumption without addressing production sources.
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.
3. How is work defined in terms of force and displacement?
- A. Work is the product of force and displacement in any direction
- B. Work is done only when the displacement is vertical
- C. Work is done only when the force and displacement are perpendicular
- D. Work is the product of force and displacement in the direction of the force
Correct answer: d
Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.
4. What is the purpose of the periosteum, the tough outer layer of bone?
- A. Produces red blood cells
- B. Provides protection and nourishment to bone
- C. Forms the joint surface
- D. Stores minerals
Correct answer: B
Rationale: The correct answer is B: 'Provides protection and nourishment to bone.' The periosteum is a tough outer layer of bone that serves multiple functions. It provides protection by acting as a barrier against infections and injuries. Additionally, the periosteum contains blood vessels that supply nutrients to the bone cells, aiding in bone growth, repair, and maintenance. While red blood cells are produced in the bone marrow, not in the periosteum, the periosteum's primary role is to support the overall health and integrity of the bone structure.
5. A closed system in ecology is one that:
- A. Exchanges energy but not matter
- B. Exchanges both energy and matter
- C. Exchanges neither energy nor matter
- D. Recycles nutrients efficiently
Correct answer: A
Rationale: Rationale: In ecology, a closed system is one that does not exchange matter with its surroundings but can exchange energy. This means that while energy can enter or leave the system, the amount of matter within the system remains constant. This definition aligns with option A, making it the correct answer. Options B and C are incorrect because a closed system does not exchange matter, and option D is not directly related to the definition of a closed system in ecology.
6. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:
- A. Was bored and disinterested.
- B. Found the story confusing.
- C. Was completely absorbed and engaged.
- D. Disagreed with the speaker's message.
Correct answer: C
Rationale: "Captivated" suggests the audience was completely held by the speaker's story.
