What are atoms?

Back

Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons. They combine to form molecules and make up everything around us.

Front

What is a control group in an experiment?

Back

A control group is a group in an experiment that does not receive the treatment or independent variable, serving as a benchmark to measure how the other tested subjects do.
