What happens when a polysaccharide undergoes hydrolysis

In a Hydrolysis reaction, polymers are broken down into monomers. So when a polysaccharide undergoes Hydrolysis, then it will break up into monosacharides like glucose.

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.

the fossil record provides evidence of a common ancestor to many species.
