1. Which of the following represents a form of potential energy?

• A. A moving car
• B. A spinning top
• C. A raised hammer
• D. A rolling ball

Correct answer: c

Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.

2. Which digestive enzyme is primarily responsible for breaking down proteins?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Maltase

Correct answer: A

Rationale: The correct answer is A: Pepsin. Pepsin is primarily responsible for breaking down proteins in the stomach. It is an enzyme produced by the gastric chief cells in the stomach lining and works in a highly acidic environment to break down proteins into smaller peptide fragments. Lipase, on the other hand, is responsible for breaking down fats, amylase for breaking down carbohydrates, and maltase for breaking down maltose (a type of sugar). Therefore, pepsin is the correct enzyme involved in the digestion of proteins.

3. What is the relationship between work and the displacement of an object?

• A. Work depends only on the force applied, not displacement
• B. Work is directly proportional to displacement
• C. Work is inversely proportional to displacement
• D. Work is unrelated to displacement

Correct answer:

Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.

4. Which of the following is the best approach to resolving conflicting scientific findings?

• A. Dismiss one set of findings as wrong without further investigation.
• B. Conduct additional research to identify potential sources of discrepancies.
• C. Accept the findings from the more prestigious research institution.
• D. Rely on media interpretations and public opinion to settle the debate.

Correct answer: B

Rationale: When faced with conflicting scientific findings, the best approach is to conduct additional research to identify potential sources of discrepancies. This allows for a more thorough understanding of the topic and helps in resolving the conflicting findings through a scientific and evidence-based approach. Dismissing findings without further investigation, relying on prestige, or turning to media interpretations and public opinion can lead to misunderstandings and hinder scientific progress. Conducting additional research promotes a more comprehensive and accurate understanding of the subject matter.

5. Which mineral is crucial for bone strength and is stored in bones and teeth?

• A. Calcium
• B. Iron
• C. Magnesium
• D. Potassium

Correct answer: A

Rationale: The correct answer is A: Calcium. Calcium is crucial for bone strength as it is a key mineral stored in bones and teeth. It plays a vital role in maintaining bone density and strength, helping to prevent conditions like osteoporosis. Without an adequate intake of calcium, individuals may be at risk of developing weak and brittle bones. Iron (B), Magnesium (C), and Potassium (D) are important minerals for various bodily functions, but they are not primarily responsible for bone strength and storage in bones and teeth.

6. Based on the passage, the author most likely believes that

• A. Individual actions are insignificant in addressing climate change, and only large-scale initiatives matter.
• B. Adaptation to the changing climate is impossible, and societal collapse is inevitable.
• C. Transitioning to renewable energy and sustainable practices offers hope for mitigating climate change.
• D. The scientific evidence for climate change is unreliable, and further research is needed before taking action.

Correct answer: C

Rationale: The focus on global efforts, renewable energy, and sustainable practices suggests an optimistic outlook on mitigating climate change, aligning with C.
