Which best explains why a crystal is incompressible? 0 its molecules remain in position without vibrating, o the molecules of a crystal behave like those of a gas. o there is little, if any, space left between its adjacent molecules, o its molecules switch positions when they are compressed

the answer is true.

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.
