The correct answer is fixed migration pattern.
Extinction means termination of last member of a particular species. This can be due to various factors. The reason could be natural or human interventions. The best characteristics of an organism to be less likely to face extinction are the fixed migration pattern. Migration of that particular species in a fixed pattern will make them adapt different environment. This saves the species from natural extinction. Even if the species of a particular geographical area dies the migrated species will be alive to breed and save the species from extinction.

Explanation:
Starch molecules taken into the mouth from food substances are processed to an extent of 30% of its digestion. this is carried out by a specialized protein/ an enzyme that is present in the saliva; called amylase or ptyalin. this enzyme acts on the substrate molecule which in this case is starch molecules and convert it into smaller chains of simple sugars that includes maltose and dextrin which is digested in the small intestine.

Explanation:
<span><span>a. amino acid supplements.
</span>Amino acids are polymers that creates the macromolecule of proteins. To explain clearly there are two factors that determine the shape or structure of the proteins which is mainly influenced by the amino acids.
The two factors that determine the shape of a protein </span><span><span>
1. </span> Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement. </span>
<span>2. Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure</span><span>
