Final answer:
Life can protect itself from ultraviolet radiation through mechanisms such as the ozone layer and the production of protective pigments. Some UV radiation is necessary for biological processes like vitamin D synthesis.
Step-by-step explanation:
Yes, life can protect itself from ultraviolet (UV) radiation. One of the ways this is accomplished is through the presence of the ozone layer in Earth's upper atmosphere. The ozone layer absorbs most of the dangerous UV radiation, preventing it from reaching the surface and causing severe cell damage. This protection allows life on land to exist and thrive.
In addition to the ozone layer, some organisms have developed mechanisms to protect themselves from UV radiation. For example, plants and some animals produce protective pigments, such as flavonoids, that absorb UV wavelengths of light. These pigments help shield the organisms from the harmful effects of UV radiation.
It is important to note that while excessive UV radiation can be damaging, some UV rays play useful biological roles. For example, UV rays promote the synthesis of vitamin D in human skin.
