This course consists of an examination of the unity and diversity of life. It investigates why there are so many different life forms and proceeds through Mendelian Genetics, the discovery of cells and chromosomes, DNA replication, and genetic expression. These topics then serve as a foundation knowledge supporting the study of population genetics, biodiversity, bioenergetics, animal and plant physiology, population ecology and ecosystem ecology. Emphasis is placed on related course material to current environmental issues and disease, particularly as these areas apply to military operations.
