What would happen if the step involving Gram's iodine was inadvertently left out of the Gram staining procedure?
Gram staining refers to separating bacterial species into two groups, gram-positive and gram-negative, which defines the physical and chemical properties. Skipping a step in this process could result in a mixed group of the bacterial species.
What would you expect from a gram stain done on a slide that was heated too hot during the heat-fixed smear?
A Gram stain refers to a staining technique for the identification of bacteria. A Gram stain done on a slide that was heated too hot during the heat-fixed smear will destroy the cell wall of the bacteria.
Do all cells move by using flagellum?
No, many are what we would call fixed. If they are bacteria, many do not move except if the place they are in (a tissue for example) would slide or move in some way.
Can you clearly see bacteria from a cotton swab at 900x magnification?
Most likely not, because the cotton fibers would probably get in the way. Besides, you would need the light to shine through the cotton swab in order to see the bacteria. An above light source work either. Sorry. :/ One thing you could do though is find a slide, or a pretty clear and thin piece of glass, moisten the swab a bit, and then smear it on the slide then look at it through your microscope.
What would happen if a slide had high friction?
If a slide had high friction, it would not function well as a slide. Things would either slow down during their descent or would stop completely (if the coefficient of friction were sufficiently large).You would either stop in mid slide, burn your bottom,or shred the seat of your pants.
Purpose of fixing the bacterial film?
The purpose of heat fixing the bacteria to the slide is so during the gram staining procedure the bacteria doesn't wash off. If you didn't heat fix the bacteria to the slide, it would not stay on the slide.
How would you define a properly prepared bacterial smear?
the bacteria are evenly spread out on the prepared slide in such a concentration that they are adequately separated from one another bacteria are not washed off the slide during staining bacterial form is not distorted

What is the helpful effect of friction?
It enables us to move: without friction we would be in a permanent skid. It allows us to hold things: they would just slide away.
Why is there need to fix the bacteria to the slide?
To heat fix a bacterial smear you would put the specimen on the slide and either put slide on a slide warmer or over a Bunsen burner for a few seconds. Heat fixing a bacterial smear does kill the specimen but it makes the bacteria stick the slide to withstand the rinsing process.

Is slide future tense?
No, "slide" is the present tense. The future tense would be "will slide".
What is the procedural difference between using broth and agar as a source of bacteria for preparing a smear?
If your colonies were grown in broth, you can simply use your loop to collect loopfuls of liquid medium and smear that onto a glass slide. If they were grown on an agar plate you would have to add a few drops of water to the surface of the glass slide.
How will a hot wheel car go faster down a wet ramp then a dry ramp?
The weels would slide The weels would slide The weels would slide
Is it right to use the same knife to prepare raw chicken and raw cucumbers?
Absolutely not. Raw chicken contains Salmonella and there is nothing in a cucumber that would neutralize that. By using the same knife to prepare raw chicken and then ANY vegetable results in cross-contamination.
