Give the term for the change that may occurto DNA as a result of environmental conditions.

A mutation is a change that occurs in our DNA, it can be because of the mistake during DNA replication or because of environmental conditions, some DNA mutated to make our body better in our environment. Like example a plant that live in a very hot area with lack of water develop their DNA and make them to have some spikes to trap air and cool their leaves.

Not only animals, bacteria or virus also can be mutated to be stronger, like example the new mutated corona virus is spreading faster.
