Question

Quizplus · Accepted Answer

The release of chemical signals by keratinocytes that have been damaged by UV light, which increases the production of melanin, is an example of negative feedback. This process helps to protect the skin from further UV damage by increasing melanin production, which absorbs and dissipates UV radiation, thereby maintaining homeostasis by preventing further damage.
