What happens if you don't heat fix a smear prior to staining of a bacterial slide?
smear will be washed( no smear will be left on the slide)
Microbiology How does the charge on a Microorganism affect staining Which staining protocols rely on which charges What are the outcomes?
The charge of the microorganism is usually negative. The cell membrane is a phospholipid bilayer which is polar, the outside is usually negative. Depending on the staining protocol, a dye will be repelled by or attracted to the cell. Sometimes you use two different dyes- one to color the cell and then one to color the background or surrounding area. Sometimes you want to color the inside of the cell, so you need to melt the cell membrane or cell wall away with heat or chemicals. This allows the dye back in. Sometimes there are steps to resolidify this barrier to trap the dye inside prior to rinsing the slide with water or whatever. These steps are tricky and easy to screw up completely, resulting in a clear or invisible specimen because the dye didn't "take".
Write two reasons why the process of cannin foodputting food in tins kills microbes?
prior to the canning all bacteria in the food are killed and the canning prevents new bacteria from infecting and spoiling the canned food Food that is put into canning jars is not sterile, thereby allowing bacteria to grow. Canning sterilizes the food and the jar, killing any thing in the jar. Water boils at 212 which is the temperature for sterilization. If using a presure canner, the combination of the pressure and the boiling sterilize meats, veggies, etc.
When DNA is in long strands prior to colling?
When DNA is in long strands prior to coiling it is in the form of : Chromosomes
Why is DNA transmitting information important?
Let's consider animals. The genetic information needed for a zygote to develop into an adult animal comes from the prior generation. If that information were not passed on from the parents, there would be no offspring.
Why is it imortant to immoblize the bacteria on the slide prior to staining?

What is the purpose of using an antiseptic on a patient prior to surgery?
To prevent bacteria from the skin getting into the incision.
Why cant methylene blue be used in place of nigrosin in negative staining?
Because negative staining requires the use of an acidic stain, which will not penetrate the cells because of the negative charge on the surface of the bacteria. As a result, the unstained cells can be easily identified against the colored background.
What is meant by the term 'de-waxing' and why is it done before staining tissues?
it is a petrochemical plant process where heavy waxes are removed from crude oils and reformed products prior to further treatment
