b. chemically fixed to the slide
c. sterilized completely air dried

Answer 1

Answer:

Before staining and observing a microbe under a microscope, a smear must be prepared. The goal of smear preparation is to place an appropriate concentration of cells on a slide and then cement them there so that they do not wash off during the subsequent staining procedure.
