The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.

Answer:

Luckily I did the same thing and it was in my docs

Explanation:

Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.

Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.
