Several words of your report are left indecipherable, but you still remember everything. Please do your best filling the blanks:
In order to observe the basic morphology of the bacteria, I decided to do a ______ stain with Methylene blue after heat ______ ing the bacterium to the slide. First I used the ______ focus knob with the 4X ________ lens to find the best place on the slide to view. From there I kept increasing the magnification until I had the ______ X oil immersion lens in place. Given my 10X ______ lenses, that gave me a total magnification of ______X. The sample seems to contain many ______ bacteria, which look like clusters of grapes. I believe there was a contamination issue collecting the sample, because there are also a few ______ bacteria –rods that are lined up end to end like E.coli. I hear a strange noise in my laptop, so I am going to
