1. When an atom gains or loses electrons, it becomes a(n):

• A. Molecule
• B. Isotope
• C. Ion
• D. Compound

Correct answer: C

Rationale: Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion.

2. Which of the following is the main organ responsible for storing energy?

• A. Liver
• B. Heart
• C. Kidneys
• D. Adipose tissue

Correct answer: D

Rationale: Rationale: - Adipose tissue, commonly known as body fat, is the main organ responsible for storing energy in the form of triglycerides. - The liver plays a role in energy metabolism by regulating glucose levels and storing glycogen, but its primary function is not energy storage. - The heart is a muscular organ responsible for pumping blood throughout the body and does not play a significant role in energy storage. - The kidneys are vital organs responsible for filtering blood and regulating fluid balance, but they are not primarily involved in energy storage.

3. How is work defined in terms of force and displacement?

• A. Work is the product of force and displacement in any direction
• B. Work is done only when the displacement is vertical
• C. Work is done only when the force and displacement are perpendicular
• D. Work is the product of force and displacement in the direction of the force

Correct answer: d

Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.

4. Ms. Valencia is responsible to the number of personnel reporting to her. This principle refers

• A. Span of control
• B. Unity of command
• C. Carrot and stick principle
• D. Esprit d’ corp

Correct answer: B

Rationale: The correct answer is B: Unity of command. Unity of command is a fundamental principle of management stating that each employee should receive orders from only one supervisor to avoid confusion and ensure clarity in the chain of command. In this scenario, Ms. Valencia's responsibility for the number of personnel reporting to her aligns with the concept of unity of command. Span of control refers to the number of subordinates a supervisor can efficiently manage, while the carrot and stick principle involves motivating employees through rewards and punishments. Esprit d’ corp refers to the sense of unity and camaraderie within a group.

5. Certain medications can suppress the immune system to treat autoimmune diseases or prevent organ rejection after transplants. What is a potential risk associated with immunosuppressive drugs?

• A. Increased risk of developing allergies
• B. Increased susceptibility to infections
• C. Both a and b
• D. Neither a nor b

Correct answer: C

Rationale: The correct answer is C: 'Both a and b.' Immunocompromised individuals, who take immunosuppressive drugs, are at an increased risk of developing allergies due to the altered immune response. Additionally, these drugs suppress the immune system's ability to fight off infections, making individuals more susceptible to various pathogens. Therefore, both increased risk of developing allergies and increased susceptibility to infections are potential risks associated with immunosuppressive drugs, making option C the correct choice.

6. The tonsils and adenoids, located in the throat, are part of the:

• A. Lymphatic system
• B. Endocrine system
• C. Respiratory system
• D. Digestive system

Correct answer: A

Rationale: The correct answer is A: "Lymphatic system." The tonsils and adenoids are part of the lymphatic system, which plays a crucial role in the body's immune response. These tissues help trap and fight off bacteria and viruses that enter the body through the mouth and nose. The lymphatic system is responsible for producing white blood cells and antibodies that help protect the body from infections. Therefore, the tonsils and adenoids are essential components of the lymphatic system, not the endocrine, respiratory, or digestive systems.
