Melanin is a skin pigmentation that absorbs and dissipates broadband UV rays. Since UV radiation causes DNA damage, melanin pigments protect the skin and reduce the risk of cancer. When skin is exposed to sunlight, melanin production is increased, causing the skin to tan. This demonstrates that Select one: a. the environment causes mutations that have no effect on the chance of survival b. the expression of some genes is influenced by the environment c. the environment causes mutations that increase the chance of survival d. the environment causes mutations that have a large effect on the chance of survival
