Homework Answers
Here, correct option is obviously: (D)
Culture media may be classified into several categories depending on their composition or use. A chemically-defined (synthetic) medium is one in which the exact chemical composition is known. A complex (undefined) medium is one in which the exact chemical constitution of the medium is not known.
Add Answer to:
complex media may be differentiated from chemically defined media
in that?
