1. Which of the following is evidence that the controlling process is effective?

• A. The things that were planned are done
• B. Physicians do not complain.
• C. Employees are contended
• D. There is an increase in customer satisfaction rate.

Correct answer: A

Rationale: The correct answer is A: 'The things that were planned are done.' This is evidence that the controlling process is effective because it indicates that the organization is able to execute its plans successfully. When planned tasks and activities are completed as intended, it shows that the controlling function is ensuring that operations are on track and that deviations are being corrected. The completion of planned tasks also demonstrates that resources are being effectively utilized and that performance is being monitored and controlled. The other options do not directly relate to the effectiveness of the controlling process. Physicians not complaining, employees being contented, and an increase in customer satisfaction rate could be influenced by various factors and may not necessarily be solely attributed to the effectiveness of the controlling process.

2. A car brakes to a stop on a level road. Which of the following forces does NOT do work on the car?

• A. The braking force applied by the wheels
• B. The normal force from the road
• C. The gravitational force on the car
• D. The friction force between the tires and the road

Correct answer: B

Rationale: While the other forces do work by changing the car's motion or energy, the normal force acts perpendicular to the motion and doesn't contribute to the car's stopping.

3. You design an experiment to test the effectiveness of a new fertilizer. Which of the following factors would be considered a dependent variable?

• A. The type of fertilizer used
• B. The size and age of the plants
• C. The amount of plant growth observed
• D. The cost of the fertilizer per unit

Correct answer: C

Rationale: The dependent variable is the factor that is being measured or observed in an experiment. In this case, the amount of plant growth observed is the variable that is being influenced by the independent variable, which is the type of fertilizer used. The size and age of the plants (option B) could potentially be controlled variables, while the type of fertilizer used (option A) is the independent variable being tested. The cost of the fertilizer per unit (option D) is not directly related to the plant growth being measured in this experiment.

4. When a car brakes to a stop, friction between the tires and the road acts as:

• A. A balanced force
• B. An unbalanced force causing acceleration
• C. An unbalanced force causing the car to remain at rest
• D. No force at all

Correct answer: B

Rationale: Friction opposes the car's motion, acting as an unbalanced force that decelerates the car and brings it to a stop.

5. Eliminate the function NOT attributed to the lymphatic system.

• A. Fluid drainage from tissues
• B. Immune response via white blood cell production
• C. Nutrient transport throughout the body
• D. Waste removal through lymph nodes

Correct answer: C

Rationale: Rationale: A) Fluid drainage from tissues: This function is attributed to the lymphatic system. Lymphatic vessels collect excess fluid from tissues and return it to the bloodstream. B) Immune response via white blood cell production: The lymphatic system plays a crucial role in the body's immune response by producing and transporting white blood cells, such as lymphocytes, which help fight infections. C) Nutrient transport throughout the body: Nutrient transport is primarily carried out by the circulatory system (blood vessels), not the lymphatic system. The circulatory system transports nutrients, oxygen, and hormones to cells and removes waste products. D) Waste removal through lymph nodes: The lymphatic system helps remove waste and toxins from the body by filtering lymph through lymph nodes, where harmful substances are trapped and destroyed by immune cells. Therefore, the function NOT attributed to the lymphatic system is C) Nutrient transport throughout the body.

6. Which of the following is an example of an aromatic compound?

• A. Ethanol
• B. Toluene
• C. Acetone
• D. Butanal

Correct answer: B

Rationale: Toluene is an aromatic compound. The other choices are not aromatic compounds.
