Question

which of the following is not an effect of ultraviolet radiation?
loss in skin pigmentation
reduced amounts of elastic fibers in the dermis
chromosomal damage in germinative cells or melanocytes
increased activity by melanocytes
production of cholecalciferol within epidermal cells

Explanation:

Ultraviolet radiation stimulates melanocytes, causing an increase in skin pigmentation (not loss). It can damage elastic fibers in the dermis, cause chromosomal damage in germinative cells or melanocytes, increase melanocyte activity, and trigger production of cholecalciferol in epidermal cells.

Answer:

loss in skin pigmentation
