1. Which of the following is a characteristic of unsaturated fatty acids?

• A. They are solid at room temperature.
• B. They contain only single bonds.
• C. They have a higher melting point.
• D. They contain double or triple bonds.

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

• A. Staffing
• B. Scheduling
• C. Recruitment
• D. Induction

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.

3. According to the Law of Conservation of Energy, the total amount of energy in a closed system:

• A. Increases over time.
• B. Decreases over time.
• C. Remains constant.
• D. Depends on the temperature of the system.

Correct answer: C

Rationale: Rationale: According to the Law of Conservation of Energy, the total amount of energy in a closed system remains constant. This means that energy cannot be created or destroyed within the system, but can only be transformed from one form to another. As a result, the total energy within the system is conserved and does not change over time. This principle is fundamental in understanding energy transformations and interactions within physical systems.

4. Your hypothesis predicts that exposing plants to classical music will enhance their growth. How could you design an experiment to test this hypothesis?

• A. Play classical music to all plants in the greenhouse and compare their growth to a control group without music.
• B. Select plants with personal preferences for classical music and compare their growth to plants who dislike it.
• C. Play different genres of music to separate plants and analyze which genre promotes the most growth.
• D. Observe the behavior of plants listening to music and measure their happiness levels.

Correct answer: A

Rationale: To test the hypothesis that exposing plants to classical music enhances their growth, the most appropriate experimental design would be to play classical music to all plants in the greenhouse (experimental group) and compare their growth to a control group of plants that are not exposed to any music. This design allows for a direct comparison between the effects of classical music exposure on plant growth, eliminating confounding variables that may arise from individual plant preferences or different music genres.

5. Choose the most appropriate word to complete the sentence "He was _____ about his upcoming presentation."
