Adaptation:Question 1 A population of insects has brown- and green-colored individuals. The ratio of brown and
green colors in the population does not change over many generations.
What is the most likely reason for this?

answer; i believe that the correct answer is (light);

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
