Answer:
Independent Variable: Time each plant is exposed to daylight.
Dependent Variable: Hours of exposure
Constant Variables: Species of plant, location of each plant, amount of soil, amount of water, and tempurature.
Explanation:
Independent variable: the variable that stays the same.
Dependent: the measurement that is used to measure the independent variable.
Constant: the variables that stay the same in a experiment.

The answer is A restriction enzymes cut DNA at specific regions.
Answer:
During the day plants produce oxygen by splitting water molecules in the light-dependent reactions of photosynthesis. At the same time plants use cellular respiration to produce some of the carbon dioxide needed by the light-independent reactions to make sugars. During the night plants produce carbon dioxide because cellular respiration takes place
Explanation:
Photosynthesis is the manufacture of organic food materials in presence of sunlight energy while respiration is the breakdown of food materials in the presence of oxygen. Photosynthesis produces oxygen as a by-product that is used in respiration. Respiration produces carbon dioxide that is used in photosynthesis.
