How many different proteins composed of 100 amino acids could possibly exist?

The number of possible proteins in humans is twenty.

The number of amino acids you can use it's called n, and the number of possible proteins then will be P=20^n.

In this case, you have 100 amino acids if you replace the n in the equation P=20^100 possible proteins.

age range would be the answer

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
