D) Gases such as carbon dioxide and methane
And the more of these from gas emissions, etc. then the more global warming.
FYI: ozone helps to blocks cosmic gamma rays from reaching earth
As powerful as diffusion is, cells sometimes must move materials in the opposite direction—against a concentration difference. This is accomplished by a process known as active transport. As its name implies, active transport requires energy.

Enzymes <em><u>act as catalysts in Chemical reaction of cells. </u></em>And they <u><em>can lower the required activiation energy for reaction in living organisms. </em></u>
