Alab technician needed to make a wet mount slide of their cheek cells. The tech made
his slide and placed it on the microscope stage. Then he got ready to view his cheek
cells by following these procedures.
1. Looking through the eyepiece, the technician adjusted the diaphragm so field of
vision was lit.
2. The technician looked at the stage from the side and lowered the body tube so the
high power objective was almost touching the slide.
3. Looking into the eyepiece, he very slowly turned the coarse adjustment to bring the
cells into focus.
What suggestion would you make to the technician to CORRECTLY use the microscope
to view his cheek cells?
do not look at the stage when lowering the body tube

The question is incomplete as it does not have the options which are:

A) close the diaphragm

B) start with the low power objective

C) do not look at the stage when lowering the body tube

D) start with the body tube raised and lower it while looking through the eye piece

Option-B

Explanation:

In the given question, the technician is trying to observe the cheek cells in the light microscope. The person prepares the wet slide of the sample and tries to observe the sample using the protocol provided in the question.

In these options, the technician is not following the rules to observe the slide in the microscope that always observes the specimen using an objective lens with lower power. Then increase the power of the objective lens to increase the magnification of the sample.

Thus, Option-B is the correct answer.
