1. What is the term for the shedding of the outermost layer of the epidermis?

A. Desquamation
B. Exfoliation
C. Keratinization
D. Epidermolysis

Correct answer: A

Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.

2. What happens to the internal energy of a system when it performs work on its surroundings?

A. It increases.
B. It decreases.
C. It remains the same.
D. Information insufficient

Correct answer: B

Rationale: When a system performs work on its surroundings, it loses internal energy in accordance with the first law of thermodynamics.

3. When light reflects from a surface, what determines the angle of reflection?

A. The material of the surface
B. The wavelength of the light
C. The angle of incidence
D. The intensity of the light

Correct answer: C

Rationale: The angle of reflection is always equal to the angle of incidence according to the law of reflection, regardless of the material, wavelength, or intensity.

4. 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.

5. Acknowledge the organ devoted to blood filtration.

A. Liver
B. Kidneys
