1.) why is the ozone layer important? What is it? And how is ozone created?

The ozone layer is important because it filters harmful ultraviolet radiation as it travels from the sun to the surface of the Earth.

a layer in the earth's stratosphere at an altitude of about 6.2 miles (10 km) containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.

Ozone is created when the kind of oxygen we breathe—O 2 —is split apart by sunlight into single oxygen atoms.

Explanation:

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
