1. What property of a substance remains constant regardless of its location in the universe?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: a

Rationale: Mass is an intrinsic property of matter that remains constant regardless of its location in the universe.

2. 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.

3. What type of energy does a stretched rubber band possess?

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

Correct answer:

Rationale: When a rubber band is stretched, it stores potential energy due to its position or state.

4. Which hormone stimulates the release of calcium from bones and increases blood calcium levels?

• A. Parathyroid hormone (PTH)
• B. Calcitonin
• C. Growth hormone
• D. Testosterone

Correct answer: A

Rationale: The correct answer is A: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands and plays a crucial role in regulating calcium levels in the blood. When blood calcium levels are low, PTH is released to stimulate the release of calcium from bones, increase calcium absorption in the intestines, and reduce calcium loss in the kidneys. This process helps to maintain the necessary balance of calcium in the body. Calcitonin, on the other hand, works in opposition to PTH by decreasing blood calcium levels. Growth hormone primarily stimulates growth and development of tissues, while testosterone is a male sex hormone and does not directly impact calcium regulation.

5. Which element is used in fluorescent lamps and emits ultraviolet light when excited?

• A. Mercury
• B. Neon
• C. Argon
• D. Krypton

Correct answer: A

Rationale: Mercury vapor in fluorescent lamps generates UV light that excites phosphors on the lamp's inner surface, producing visible light.

6. Which term describes the quantity of matter in an object and is measured in kilograms or grams?

• A. Weight
• B. Mass
• C. Volume
• D. Density

Correct answer: B

Rationale: Mass is the term that describes the quantity of matter in an object. It is typically measured in kilograms or grams. Weight, on the other hand, is the force of gravity acting on an object and is measured in newtons. Volume is the amount of space an object occupies, typically measured in cubic units such as cubic meters or cubic centimeters. Density is the mass of an object per unit volume and is measured in units such as kilograms per cubic meter.
