1. What type of energy is possessed by an object due to its position or configuration?

• A. Kinetic energy
• B. Thermal energy
• C. Potential energy
• D. Electrical energy

Correct answer: c

Rationale: Potential energy is the energy possessed by an object due to its position or state.

2. She knows that there are external forces that influence changes in his unit. Which of the

• A. Memo from the CEO to cut down on electrical consumption
• B. Demands of the labor sector to increase wages
• C. Low morale of staff in her unit
• D. Exacting regulatory and accreditation standards

Correct answer: A

Rationale: The correct answer is option A: 'Memo from the CEO to cut down on electrical consumption.' This choice represents an external force that can influence changes in the unit by setting a directive from top management to reduce electricity usage, impacting operations and decisions within the unit. While options B, C, and D may also affect the unit to some extent, they are not as directly tied to external influences as the CEO's memo. The demands of the labor sector (option B) and low staff morale (option C) are internal factors, while regulatory and accreditation standards (option D) are more overarching guidelines rather than specific external forces impacting the unit. Therefore, the most direct and relevant external force in this scenario is the directive from the CEO, making option A the correct choice.

3. Define the term "velocity" in relation to motion.

• A. Speed in a specific direction
• B. Distance traveled in a given time
• C. Rate of change of position
• D. Acceleration due to gravity

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.

4. The two main divisions of the skeletal system are:

• A. Upper and lower body bones
• B. Axial and appendicular skeleton
• C. Long and short bones
• D. Compact and spongy bone

Correct answer: B

Rationale: The correct answer is B: Axial and appendicular skeleton. The skeletal system is divided into two main parts: the axial skeleton, which includes the skull, rib cage, and vertebral column, and the appendicular skeleton, which includes the bones of the arms, legs, shoulders, and hips. This division is based on the location and function of the bones in the body. The other options are incorrect as they do not represent the main divisions of the skeletal system. Understanding these divisions is important for studying the structure and function of the human skeletal system.

5. The energy released during a chemical reaction is called:

• A. Kinetic energy
• B. Potential energy
• C. Heat energy
• D. Exothermic energy

Correct answer: D

Rationale: Exothermic means "outward heat," indicating energy is released during the reaction.

6. The moon-shaped white structures at the base of fingernails are called:

• A. Lunulae
• B. Cuticle
• C. Hyponychium
• D. Matrix

Correct answer: A

Rationale: The correct answer is A, "Lunulae." The moon-shaped white structures at the base of fingernails are called lunulae. These are most visible on the thumb and are the visible part of the nail matrix. The lunulae appear white because the nail matrix underneath is not visible due to its thickness. Cuticle (B) refers to the thin layer of skin at the base of the nail, hyponychium (C) is the skin located under the free edge of the nail, and matrix (D) is the tissue at the base of the nail where growth occurs. Therefore, the correct term for the moon-shaped white structures is lunulae.
