Physiologists study the life functions of plants and animals. Zoologists study the origins, behavior, diseases, and life processes if animals. Biotechnology is an area of biology that is growing rapidly. Some biologists, for example, make changes to the genetic material of plants or animals. These changes are then used in the fields of medicine, pharmacy, agriculture, foods, and chemicals.
Some biologists hold faculty positions at universities or colleges.
They teach or do research, and often do both. Biologists use computers to store, process, and analyze research data. They may write computer programs for specific uses. They also write papers and give speeches about their research. Biologists is in the Engineering, Science, and Technologies Career Cluster.
