In 1986, a meltdown of a nuclear reactor in the city of Chernobyl, in Ukraine, released highly radioactive chemicals into the atmosphere. As a result, people suffered various forms of cancer because of exposure to these radioactive chemicals. Cancerous cells divide much more often than noncancerous cells and form tumors in the body.

A scientist claims that these cancers were caused by harmful mutations. He wants to make a model to support his claim.

Which statement best describes what the scientist’s model needs to represent in order to support his claim?
