2. What is the difference between constructive and destructive interference of waves?
- A. They have the same effect on wave amplitude.
- B. Constructive interference increases amplitude, while destructive interference decreases it.
- C. They only affect light waves, not sound waves.
- D. They depend on wave speed, not amplitude.
Correct answer: B
Rationale: Constructive interference occurs when peaks of two waves overlap, resulting in a higher combined amplitude. Destructive interference happens when peaks and troughs overlap, cancelling each other out and reducing the overall amplitude.
3. What is the functional group present in amines?
- A. Hydroxyl
- B. Carbonyl
- C. Amine
- D. Nitro

4. Which type of carbohydrate is the main component of the cell wall in plant cells?
- A. Starch
- B. Glucose
- C. Cellulose
- D. Chitin
Correct answer: C
Rationale: The correct answer is C: Cellulose. Cellulose is a structural polysaccharide and the main component of the cell wall in plant cells. Starch, option A, is a storage polysaccharide found in plants, while glucose, option B, is a simple sugar and a basic unit of carbohydrates, not the main component of plant cell walls. Chitin, option D, is a structural polysaccharide found in the exoskeletons of arthropods and fungal cell walls, not in plant cell walls. Understanding the unique composition of plant cell walls helps in differentiating the types of carbohydrates present in various cellular structures.
5. What property of a substance measures the amount of matter per unit volume?
- A. Mass
- B. Weight
- C. Density
- D. Volume
