GENERIC AVAILABLE: Yes. USES: Atorvastatin is used for the treatment of elevated total cholesterol, LDL, and triglycerides and to elevate HDL cholesterol. The effectiveness of atorvastatin in lowering cholesterol is dose-related, meaning that higher doses reduce cholesterol more.
Why is the ozone layer important for Earth's life forms? The ozone layer is important for Earth's life forms because it protects Earth from harmful ultraviolet radiation. This made the environment able to support more complex life forms. 2.) Describe the role of cyanobacteria in changing Earth's early atmosphere. Cyanobacteria helped in changing Earth's atmosphere by adding an abundance of oxygen to it. To this day cyanobacteria's account for 20% to 30% of photosynthesis today.
The ozone layer is essential for complex living organisms (like you and me) to exist. Without the ozone layer, all but very simple life forms would be destroyed by the action of ultraviolet light. Some chemicals, particularly CFCs, destroy ozone in the upper atmosphere.A CFC is a chlorofluorocarbon molecule. It is similar to an alkane with all the hydrogen atoms replaced with chlorine and fluorine atoms.In the presence of ultraviolet light a CFC molecule will decompose producing highly reactive chlorine free radicals.These chlorine free radicals will react with ozone molecules and turn them back into oxygen molecules.he ozone layer is essential for complex living organisms (like you and me) to exist.
