Answer 2

The ozone layer protects the DNA of all surface dwelling life, by absorbing UltraViolet-B from our Sun. More detail The ozone layer is the product of very short wave Ultraviolet light (UV-B) breaking apart oxygen molecules. When ozone is formed, it serves to block energetic UV (UV-B) that other molecules don't, and acts to moderate day / night temperature swings a little bit. Ozone absorbs UV-B, which would otherwise damage our DNA, and the DNA of all surface dwellers on Earth (including phytoplankton in the oceans). This absorption of UV-B or more energetic light breaks the ozone down into an oxygen molecule and a single oxygen atom. A few of these fragments reassemble as ozone. But primarily UV-B is required to break apart more oxygen to make replacement ozone.

Answer 3

so its B right? (:

Answer 4

yes

Answer 5

have you taken chemistry?

Answer 6

No @nincompoop only biology well im taking biology at the moment im having a very hard time figuring this out at the moment (: But to answer your question no I have not taken chemistry yet (:

Answer 7

I would like to suggest to take chemistry along side with biology or chemistry first then biology. A lot of the essentials, particularly in cells, genes and biological molecules require background in chemistry to make it easier to understand.
