What else can I help you with?
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.
How would you prepare a amoeba specimens for observation?
To prepare an amoeba specimen for observation, you would first collect a sample containing the amoebas. Then, place a drop of the sample on a microscope slide and cover it with a coverslip. Finally, observe the specimen under a microscope, adjusting the focus to see the amoebas clearly.
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?
Fixing the bacterial film helps preserve the structure of the microbial community and facilitates further analysis such as microscopy and molecular studies. It allows for a more accurate representation of the bacteria present and their interactions.
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 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.
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.
Would you need to suspend a liquid culture in water in order to make a smear. explain?
I'm not sure but since you are placing a cell suspension on a microscopic slide, you will just have to let it air-dry. This will lead to the suspension to dry, thus allowing it be gently heated to allow it to stick to the slide.
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.

Is slide future tense?
No, "slide" is the present tense. The future tense would be "will 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
