The process of natural selection
1. is possible only when spontaneous mutations are forced by environmental pressures
2. is fundamentally a natural process that operates independent of the condition of the environment
3. shapes the genetic characteristics of a species as a consequence of adaptation
4. alters the genetic code in random and unpredictable ways
5. modifies the phenotype of individual members of a species

3. shapes the genetic characteristics of a species as a consequence of adaptation

Explanation:

Natural selection is a process characterized by how plants and animals that are able to adapt to changes in their environment are able to survive and reproduce while those that are unable to adapt do not survive.

In natural selection, those variations in the genotype which increases an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations.

Natural selection is a way of enhancing the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.
