The Earth is the center of the universe. The Earth is flat. All organisms are either plants or animals.

independent variable

The experimental factor that is manipulated; the variable whose effect is being studied.

dependent variable

The outcome factor; the variable that may change in response to manipulations of the independent variable.

What statement describes a cell?

Protista

Unicellular and Multicellular organisms; autotrophic and heterotrophic organisms.

standardized variable

any factor held constant for all subjects in an experiment

Particles that make up molecules are called
