Question

an examination of the microscopic structure and staining properties of a bacterium would represent a(n) method of identification. need help? review these concept resources.

Explanation:

The problem is about identifying the method for examining bacterial microscopic structure and staining properties. In biology (a subfield of Natural Science), the method of identifying bacteria by their microscopic structure (like cell shape, arrangement) and staining properties (like Gram staining) is called the morphological and staining (or phenotypic) method. Specifically, this falls under microbiology (a part of Biology) where such techniques are used for bacterial identification. The key here is recognizing that studying bacterial structure and staining is a biological (microbiological) approach to identification.

Answer:

morphological (or phenotypic)
