study living organisms: how they grow, reproduce, and interact among
themselves and with their environment. Specialization in a
particular aspect of biology is common (for example, neuroscience,
which includes study of the brain, sensory perception, and nerve
cell signaling). Regardless of the area of specialization, in modern
biology full understanding of a process requires integrating studies
at many levels of organization: populations, individual organisms,
organ systems, cells, and molecules.
Biologists carry out research in universities, government
laboratories, and industry. The research may be "basic," exploring a
fundamental question to further our understanding of life processes.
Such research may be in the laboratory or "in the field." Research
may also be "applied," seeking to develop a new or better drug or
biological pesticide, a new vaccine, or a way to conserve an
endangered species, for example. Biologists in universities teach in
addition to conducting research. These biologists must seek grant
support for their research, from government or foundations.
