Dna replication:
a) requires the cooperation of over a dozen enzymes and other proteins.
b) requires dna polymerase and rna polymerase.
c) is a very fast process that results in numerous errors.
d) is a slow process that results in virtually no errors.

The answer is A) Requires the cooperation of over a dozen enzymes and other proteins.

Explanation:

DNA replication is a very complex process that involves many enzymes such as the helicase, which breaks the hydrogen bonds between the two DNA strands, the SSBs that avoid the strands from coming back together, and that only for the beginning of the process. But there are many more enzymes and molecules helping the replication.

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.
