Problem:OPTIONS:
- chromosomes
- polymers
- bacteria
- plastids

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:
****
A: plastids

Answer the following question given this paragraph: Neutralization reactions between an acid and a base yield a salt and water. In some cases, this results in a completely neutral solution. However, some salts are weakly acidic or basic. How can we tell whether a given salt will act as an acid or base? Looking at the relative strengths of the acid and base that were used to form the salt can give us information on the acid-base properties of the resulting solution. Q: What kind of reactions between an acid and a base yield a salt and water? A:
OPTIONS:
- oxidation
- evaporation
- distillation
- neutralization
neutralization
