Biology

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1] 

Biology is a vast subject containing many subdivisions, topics, and disciplines.

Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2]  -From Wikipedia.org
 * 1) Cells are the basic unit of life
 * 2) New species and inherited traits are the product of evolution
 * 3) Genes are the basic unit of heredity
 * 4) An organism will regulate its internal environment to maintain a stable and constant condition
 * 5) Living organisms consume and transform energy.

In the E.P.I.C. system, Biology concerns the makeup of cells and their constituant components. The focus is more on the cells and the organs they make up then the actual chemisty they make up. High levels of Technology are capable of emulating biology, thus allowing for the gap between the two tiers to be briged. As for Magic, the link there depends solely on the biology involved, although most Biology-based entities with a brain are capable using using magic eventually.
