Biology is a natural science that concerns the study of life and living organisms. Advances in biology have helped scientists do things such as develop better medicines and treatments for diseases, understand how a changing environment might affect plants and animals, produce enough food for a growing human population and predict how eating new food or sticking to an exercise regimen might affect our bodies. Thus, while it is custom to separate the study of plants (botany) from that of animals (zoology), and the study of the structure of organisms (morphology) from that of function (physiology), all living things share in common certain biological phenomena—for example, various means of reproduction, cell division, and the transmission of genetic material. For example, is a virus alive or dead? It deals with all aspects of the cell including cell anatomy, cell division (mitosis and meiosis), and cell processes including cell respiration, and cell death. Whenever a change in a gene (a mutation) occurs, there is a change of some kind in the organism that contains the gene. life.
