As the new cell grows, its plasma membrane needs to expand to con-
tain the increased volume of the cell. (a) calculate the surface area of
each cell using the formula for the surface area of a sphere: a = 471?
(b) how much area of new plasma membrane will the new cell have
to synthesize as it matures?
explain

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
