HELP ME PLEASE What other examples have you seen of living things that are basically similar but have range of differences or variations in a characteristic or treat

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
