1. A baseball is thrown into the air. At the peak of its trajectory, which of the following forces is acting on the ball?

• A. Only gravitational force
• B. Only the force of air resistance
• C. Both gravitational force and the force of air resistance
• D. Neither gravitational force nor the force of air resistance

Correct answer: A

Rationale: At the peak, the ball momentarily stops moving upwards. Its inertia keeps it moving horizontally, but there is no force propelling it upwards except for gravity pulling it down.

2. Electrons occupy specific energy levels around the nucleus, but not in fixed orbits. This concept is captured by the:

• A. Bohr model
• B. Quantum mechanical model
• C. Lewis structure
• D. Octet rule

Correct answer: B

Rationale: Quantum mechanical model. Unlike the Bohr model with its defined electron paths, the quantum mechanical model uses probability distributions to describe electron locations within energy levels.

3. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.

4. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."

• A. extreme
• B. great
• C. utter
• D. remarkable

Correct answer: C

Rationale: Option C emphasizes the absolute and complete accuracy of the experiment.

5. The term "bioaccumulate" refers to...

• A. The natural decomposition of organic materials.
• B. The buildup of a substance in living organisms.
• C. The contamination of seawater with chemical pollutants.
• D. The physical entanglement of animals with plastic debris.

Correct answer: B

Rationale: The passage describes microplastics entering food chains and accumulating in organisms, aligning with bioaccumulation.

6. The gradual change in a species over time in response to environmental pressures is best described by:

• A. Punctuated equilibrium (rapid bursts of evolution)
• B. Gradualism (slow and continuous change)
• C. Founder effect (genetic drift in a small population)
• D. Adaptive radiation (rapid diversification of a species)

Correct answer: B

Rationale: Rationale: A) Punctuated equilibrium refers to rapid bursts of evolution followed by long periods of stability, rather than gradual change over time in response to environmental pressures. B) Gradualism is the process by which species evolve through slow and continuous changes over time in response to environmental pressures. This gradual change can lead to the development of new traits and adaptations. C) Founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not specifically describe the gradual change in a species over time. D) Adaptive radiation is the rapid diversification of a species into a variety of forms to exploit different ecological niches, but it does not specifically refer to the gradual change in response to environmental pressures. Therefore, the best description of the gradual change in a species over time in response to e
