1. Acknowledge the organ devoted to blood filtration.

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The kidneys are the primary organs responsible for filtering blood and removing waste products, excess fluids, and toxins. They play a crucial role in maintaining the body's internal environment and regulating blood pressure.

2. How does the potential energy of an object change when it is compressed?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

3. Which of the following is NOT a characteristic of a chemical reaction?

• A. Formation of new substances
• B. Release or absorption of energy
• C. Change in color
• D. Change in temperature

Correct answer: C

Rationale: While color change can be an indicator of a chemical reaction, it's not always present, and some reactions occur without a visible color change.

4. 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?

• A. 4:00 PM
• B. 6:00 PM
• C. 8:00 PM
• D. 10:00 PM

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.

5. 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.

6. Acids are generally characterized by a sour taste and the ability to:

• A. Turn litmus paper blue
• B. Conduct electricity in solution
• C. Neutralize bases
• D. React explosively with metals

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity
