Q: Answer the following question given this paragraph: Plastids are membrane-bound organelles with their own DNA. Examples are chloroplasts and chromoplasts. Chloroplasts contain the green pigment chlorophyll and carry out photosynthesis. Chromoplasts make and store other pigments. They give flower petals their bright colors. Q: Chloroplasts and chromoplasts are examples of which membrane bound organelle containing their own dna? A:

OPTIONS:
- chromosomes
- polymers
- bacteria
- plastids

A: plastids

Q: Answer the following question given this paragraph: When two or more waves meet, they interact with each other. The interaction of waves with other waves is called wave interference . Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. Amplitude is the maximum distance the particles of the medium move from their resting positions when a wave passes through. How amplitude is affected by wave interference depends on the type of interference. Interference can be constructive or destructive. Q: What is the interaction of waves with other waves called? A:

OPTIONS:
- wave mixing
- wave induction
- wave dancing
- wave interference

A: wave interference
