Chapter 1, Problem 17CYR
Summary Introduction
Introduction:
A gradient occurs when something exists in more concentration in one area than the other area. There is also a connection between those two areas. A living cell requires distinctinternal conditions, which are quite different from the external environment. This differential requirement forms the basis of a biochemical gradient.
