The risk factors cause changes to genes that regulate the cell cycle which is the reason for developing cancer in smokers' lungs. Thus the correct answer is option (C).
When radioactive materials like uranium, thorium, or radium decay in rocks, soil, or groundwater- radon, a radioactive gas, is naturally produced. Inhalation of radon-contaminated air that seeps into homes and other structures through cracks and openings is the main way that people might be exposed to radon. People are regularly exposed to the naturally occurring gas radon because the ground releases it.
According to the Surgeon General's office and the US Environmental Protection Agency, radon is considered to be the cause of more than 20,000 lung cancer deaths annually in the US. Particles of radioactive radon gas that you breathe in run the risk of becoming lodged in your lungs. Lung cancer risk rises with continued exposure to certain radioactive substances.
People who are exposed to radon have higher chances to develop lung cancer in comparison to nonsmokers. When radon levels in a residence reach or exceed 4 picocuries per liter (pCi/L) of air, the EPA advises radon mitigation.
The complete question is:
Studies have linked cigarette smoking, exposure to radon gas, and exposure to asbestos fibers with lung cancer. The model here shows the cell cycle of a cancerous cell. According to the information regarding the causes of lung cancer and the model of a cancer cell cycle, what statement describes how these risk factors lead to lung cancer?
A) The risk factors increase the size of lung cells.
B) The risk factors increase the size of the genome in the lung cell.
C) The risk factors cause changes to genes that regulate the cell cycle.
D) The risk factors decrease the ability of the affected cell to divide.
