physics

1. What property of a substance measures the amount of matter per unit volume?

Correct answer: c

Rationale: Density measures the amount of matter (mass) per unit volume of a substance.

2. Which of the following is an example of stabilizing selection?

Correct answer: C

Rationale: Rationale: - Stabilizing selection is a type of natural selection that favors the intermediate variants in a population, while selecting against the extreme traits. This results in the maintenance of the current average trait in the population. - Option A is incorrect because stabilizing selection does not favor extreme traits; instead, it favors the average trait. - Option B is incorrect because stabilizing selection does not remove individuals with extreme traits; it acts against extreme traits by favoring the intermediate variants. - Option D is incorrect because stabilizing selection does not favor one specific trait over all others; it favors the average trait by selecting against extreme traits.

3. Which energy conversion occurs in a solar cell?

Correct answer: d

Rationale: Solar cells convert solar energy (sunlight) directly into electrical energy.

4. The resolution of an optical instrument, like a microscope, refers to its ability to distinguish between:

Correct answer: D

Rationale: The resolution of an optical instrument, such as a microscope, is its ability to distinguish between very close, nearly identical objects. This means that the instrument can differentiate between two points that are close together and appear almost as one. A higher resolution allows for clearer and sharper images by minimizing the blurring effect that occurs when objects are close together. Options A, B, and C do not directly relate to the concept of resolution in optical instruments. Therefore, option D is the correct answer as it best describes what resolution entails in this context.

5. A study finds a link between increased sugar intake and obesity. Does this confirm sugar causes obesity?

Correct answer: C

Rationale: Correlation suggests a link, but other factors might contribute. Further research is needed to establish the direction and strength of any causal relationship.

6. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.
