Natural selection is a process by which organisms that are better adapted to their environment tend to increase in size. migrate. evolve new traits. survive.

Natural selection is a process by which organisms that are better adapted to their environment tend to evolve new traits. The natural selection is the process of evolution in which the individuals of organisms with a favourable set of traits tend to survive and adapt to the environment, and reproduce to pass these new evolved traits to the progeny. These new traits then become a part of the population.

survive

Explanation:

The organisms that are better adapted would survive and reproduce. They do not have new traits that they didn't have before. I took the quiz. :)

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
