Biology of the Living Earth Flashcard #1 Retake Review

Front

What is a control group in an experiment?

Back

The control group is the group that does not receive the independent variable, allowing for comparison against the experimental group.

Front

What variable is placed on the y-axis of a graph?

Back

The dependent variable is placed on the y-axis.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated in an experiment, such as the color of light in a plant growth experiment.

Front

What is the purpose of a control group?

Back

The control group serves as a baseline to compare the effects of the independent variable on the experimental group.

Front

What is a dependent variable?

Back

The dependent variable is what is being measured in an experiment, such as the heart rate of Daphnia in response to caffeine.

Front

What is an independent variable?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What does it mean to keep constants in an experiment?

Back

Constants are the factors that are kept the same throughout the experiment to ensure that the results are due to the independent variable.

Front

Why is it important to have a control group?

Back

A control group is important because it helps to isolate the effects of the independent variable, ensuring that the results are valid.

Front

What is the difference between a control group and an experimental group?

Back

The control group does not receive the independent variable, while the experimental group does.

Front

How do you identify the dependent variable in an experiment?

Back

The dependent variable is identified by what you are measuring or observing in response to changes in the independent variable.
