Answe: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Explanation:
DNA is an example of a complex biological polymer called a nuclei acid. Nucleic acids are made up of many smaller sub units called nucleotides. The components of a DNA nucleotide are deoxyribose, phosphate group, nitrogen group. There are four possible bases in a DNA molecules which includes adenine, cytosine, guanine and tymine.
Salivary amylase is an enzyme that is found in saliva in the mouth. It is an enzyme that only recognizes the glycosidic bonds between molecules of simple sugars that form the carbohydrate polymers.
It specifically targets these bonds and breaks them and does not recognize any other bonds of different substances such as protein.
Salivary amylase is alkaline in nature and cannot work in the stomach. It breaks the glycosidic bonds between the glucose molecules in starch to form maltose. Maltose is later broken down further by pancreatic amylase, into individual units of glucose.
