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.
Supply exceeds demand seems like to be the correct answer since it could be longer lasting.
I don't know what you have listed as your answer choices but: this fungus is still alive and able to reproduce.
Answer:
Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
