Careers in Focus: Biology

Hardback
Biology is the study of how living things function, how they relate to one another, and how they evolved. Because living things vary greatly in how they live and how they developed, the field of biology is broken into many distinct specialty areas, including microbiology, plant and animal physiology, ecology, epidemiology, cell biology, and marine biology. Biologists play an important role in research to fight diseases and develop life-improving technologies.
