1. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

2. Two scientists analyze the same data set on climate change, but they reach different conclusions. What is the MOST likely reason for this difference?

Correct answer: B

Rationale: Different analysis methods can lead to different interpretations, even with the same data. Biases and experience might play a role but are less likely the primary cause.

3. What is the difference between a germline mutation and a somatic mutation?

Correct answer: B

Rationale: Rationale: - Germline mutations are changes in the DNA of reproductive cells (sperm or egg cells) and can be passed on to offspring, affecting all cells in the resulting organism. - Somatic mutations are changes in the DNA of non-reproductive cells (body cells) and are not passed on to offspring. These mutations only affect the cells that arise from the mutated cell. - Option A is incorrect because somatic mutations are not passed to offspring. - Option C is incorrect because both germline and somatic mutations can affect any DNA. - Option D is incorrect because the effects of mutations, whether germline or somatic, can be beneficial, harmful, or have no significant impact.

4. What type of figurative language is used in the statement "Her laughter was music to my ears"?

Correct answer: A

Rationale: The statement directly compares laughter to music, forming a metaphor.

5. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

Correct answer: d

Rationale: Constructive interference happens when identical waves meet in phase, resulting in a wave with increased amplitude.

6. A car brakes to a stop on a level road. Which of the following forces does NOT do work on the car?

Correct answer: B

Rationale: While the other forces do work by changing the car's motion or energy, the normal force acts perpendicular to the motion and doesn't contribute to the car's stopping.
