Identify three things that can increase the rate of mutation

Some chemicals increase the mutation rate, physical agents such as radiation also increase the mutation rate. There are viruses that are mutagens as well. Also, the number of mutations that an organism produce can also be phenotypically plastic.

Hope this helps. (This is the definition my bio teacher gave me.)

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
