Burning fossil fuels has changed the atmosphere by producing a hole in the ozone.

increasing the concentration of carbon dioxide.

increasing the concentration of ozone in the atmosphere.

reducing the CFC's in the atmosphere.

ans 1. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1

Ans.2The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).

Ans3.Rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.

Ans.4.Many factors impact ground-level ozone development, including temperature, wind speed and direction, time of day, and driving patterns

And.5.Buy air-conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol products that do not use HCFCs or CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.

Explanation: Burning of fossil fuels, like gasoline, causes atmospheric change by increasing the concentration of carbon dioxide.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
