ANSWER AND EXPLAIN PLZ:)
Rudik [331]

Answer:

The independent variable in the experiment is A. the jar covers.

Explanation:

The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters.  One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed  to the independent variable).  Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.

The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Hope this helps!

Write a sentence that compares the reactants and products of photosynthesis with the reactants and products of respiration.
Anna11 [10]

Answer/Explanation:

Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.

Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products.

Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
