What is the primary reason ultraviolet radiation can both benefit and harm living organisms?
Its wavelength allows it to trigger biological processes like vitamin D synthesis but also cause DNA damage.
It is completely absorbed by the atmosphere, so it never reaches living organisms.
Ultraviolet radiation has the same wavelength as visible light, so it only affects vision.
