What is the definition of a variable in an experiment?

Back

A variable is any factor that can change in an experiment, affecting the outcome.

Front

What is the role of the control group in an experiment?

Back

The control group serves as a standard for comparison, not receiving the experimental treatment.

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods from carbon dioxide and water.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment.
