LIFE SCIENCE

Detailed explanation-1: -A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.

Detailed explanation-2: -Organisms of the same species will have similar genomes and a similar proteome, or makeup of proteins. Looking at these molecular signatures can help scientists determine if two organisms are the same species.

Detailed explanation-3: -An example would be moths of the same species with different color wings. Moths with wings similar to the color of tree bark are better able to camouflage themselves than moths of a different color. As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.
