1. What is the relationship between work, force, and displacement?

• A. Work is directly proportional to force but inversely proportional to displacement
• B. Work is directly proportional to both force and displacement
• C. Work is inversely proportional to force but directly proportional to displacement
• D. Work is inversely proportional to both force and displacement

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

2. What is the general formula for an alcohol?

• A. CnH2n
• B. CnH2n+2
• C. CnH2n-1
• D. CnH2nO

Correct answer: D

Rationale: The general formula for an alcohol is \(C_nH_{2n}O\), indicating the presence of a hydroxyl group (-OH).

3. The involuntary "fight-or-flight" response is controlled by the:

• A. Sympathetic nervous system
• B. Parasympathetic nervous system
• C. Enteric nervous system
• D. Sensory nervous system

Correct answer: A

Rationale: The correct answer is A: Sympathetic nervous system. The "fight-or-flight" response is an automatic physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. This system prepares the body for action by increasing heart rate, dilating pupils, and redirecting blood flow to muscles. The parasympathetic nervous system, on the other hand, controls the body's "rest-and-digest" response, promoting relaxation and digestion. The enteric nervous system primarily regulates the gastrointestinal system, while the sensory nervous system is responsible for transmitting sensory information to the brain. Therefore, the sympathetic nervous system is specifically responsible for initiating the fight-or-flight response.

4. Which of the following is NOT a major component of a healthy blood pressure reading?

• A. Systolic pressure (peak pressure during ventricular contraction).
• B. Diastolic pressure (pressure within arteries during ventricular relaxation).
• C. Pulse pressure (difference between systolic and diastolic pressure).
• D. Blood oxygen saturation While blood oxygen levels are crucial for overall health, they are not directly reflected in a blood pressure reading.

Correct answer: A

Rationale: The correct answer is A. Systolic pressure is a major component of a healthy blood pressure reading as it represents the peak pressure in the arteries during ventricular contraction. Diastolic pressure, representing the pressure in the arteries during ventricular relaxation, is also a key component. Pulse pressure, the difference between systolic and diastolic pressure, provides additional information about the cardiovascular system. Blood oxygen saturation, while important for overall health, is not directly measured in a blood pressure reading. Therefore, it is not a major component of a healthy blood pressure reading.

5. As a young manager, she knows that conflict occurs in any organization. Which of the

• A. Can be destructive if the level is too high
• B. Is not beneficial; hence it should be prevented at all times
• C. May result in poor performance
• D.

Correct answer: C

Rationale: Conflict in an organization is a natural occurrence that can either be constructive or destructive. Option C is the correct answer because conflict may indeed lead to poor performance if not managed effectively. When conflict is left unresolved or unaddressed, it can create tension, decrease morale, and hinder productivity. By recognizing that conflict can impact performance, the young manager can take proactive steps to address and resolve conflicts in a constructive manner to minimize its negative effects and promote a healthy work environment.

6. What is the net ionic equation for the reaction: 2HCl(aq) + Ba(OH)2(aq) → 2H2O(l) + BaCl2(aq)?

• A. 2H+(aq) + 2OH-(aq) → 2H2O(l)
• B. 2HCl(aq) + Ba(OH)2(aq) → BaCl2(aq) + 2H2O(l)
• C. 2H+(aq) + Ba2+(aq) → Ba2+(aq) + 2H+(aq)
• D. Ba(OH)2(aq) + HCl(aq) → BaCl2(aq) + 2H2O(l)

Correct answer: a

Rationale: The net ionic equation includes only the species that undergo a change during the reaction.
