(True or False) UV radiation can damage skin cells

Explanation:
UV radiation can damage skin cells. The energy in UV rays can directly alter DNA, especially UV-B, which forms thymine dimers that, if not repaired, can lead to mutations and cancer. UV-A penetrates more deeply and promotes oxidative stress by generating reactive oxygen species, damaging DNA, proteins, and lipids. This combination explains sunburn, premature aging, and higher skin cancer risk. So the statement is true. Saying not sure or choosing false wouldn’t match the well-established evidence, and a choice like “both” isn’t meaningful for a true/false item.
