1. What is the functional group present in aldehydes?

• A. Hydroxyl
• B. Carbonyl
• C. Ester
• D. Amine

Correct answer: B

Rationale: Aldehydes have the functional group -CHO, which is a carbonyl group bonded to a hydrogen atom. The other choices are associated with different functional groups.

2. He likewise stresses the need for all the employees to follow orders and instructions from

• A. Scalar chain
• B. Discipline
• C. Unity of command
• D. Order

Correct answer: B

Rationale: The correct answer is B: 'Discipline.' In a business context, discipline refers to the adherence to rules, orders, and instructions to ensure smooth operations and efficiency. The concept of discipline is essential in maintaining order, consistency, and productivity within an organization. It encompasses obeying rules, following instructions, and respecting authority. While the other options like 'Scalar chain,' 'Unity of command,' and 'Order' are important principles in management, they do not directly address the importance of employees adhering to orders and instructions, which is the central focus in this question. Therefore, 'Discipline' is the most suitable answer in this context.

3. What type of enzyme breaks down carbohydrates like starches and sugars in the mouth?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: C

Rationale: The correct answer is C: Amylase. Amylase is an enzyme specifically responsible for breaking down carbohydrates like starches and sugars in the mouth. It is produced by both the salivary glands and the pancreas. Pepsin (A) is an enzyme that breaks down proteins in the stomach, lipase (B) breaks down fats, and trypsin (D) is another enzyme that digests proteins but is produced in the pancreas and works in the small intestine. Therefore, amylase is the enzyme that targets carbohydrates in the mouth, aiding in the initial digestion process of these nutrients.

4. A concave mirror can be used to:

• A. Focus light to a single point
• B. Only create virtual images
• C. Always magnify objects
• D. Scatter light

Correct answer: A

Rationale: A concave mirror can be used to focus light to a single point because of its reflective surface that curves inward. When light rays parallel to the mirror's principal axis strike the mirror, they converge at a focal point, creating a real image. This property makes concave mirrors useful in applications like reflecting telescopes and headlights, where focusing light to a point is necessary for proper functioning. Virtual images are also created by concave mirrors, but the primary function is to focus light rather than create virtual images. Magnification of objects and scattering of light are not inherent properties of concave mirrors.

5. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

6. What is the process of cells becoming specialized to perform specific functions called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: B

Rationale: Rationale: A) Cell division refers to the process by which a parent cell divides into two or more daughter cells. B) Cell differentiation is the process by which cells become specialized to perform specific functions. During differentiation, cells acquire specific structures and functions that allow them to carry out particular roles in the body. C) Cell growth is the process by which cells increase in size and number. D) Cell regeneration is the process by which new cells are produced to replace damaged or lost cells in an organism. In this context, the process of cells becoming specialized to perform specific functions is best described as cell differentiation.
