A scientific study looked at the effect of tanning beds on DNA damage. The scientists took skin cells and exposed them to UV radiation (the type used in indoor tanning beds) for different lengths of time: some for 1 minute, some for 5 minutes, some for 15 minutes, and some for 30 minutes. They then looked for signs of DNA damage and compared the results to cells that had never been exposed to UV light. What is the independent variable in this experiment

Stevens · Answer 1

Tanning of DNA using UV light at different time (1 minutes, 15 minutes, and 30 minutes)

Explanation:

Independent variable is the variable that was controlled or change and in this case it is the tanning of DNA with UV light at different times and the dependent variable is what is measured or the effect of the change in the independent variable which is DNA damage and the control was the cells that did not receive the treatment.
