What is gram variability?
Gram variability refers to a characteristic of certain bacteria that can exhibit variability in their response to Gram staining, appearing as a mix of both Gram-positive and Gram-negative characteristics. This variability can make the identification of these bacteria challenging because their staining characteristics may not be consistent.
If you mix starch with saliva and treat it with vinegar is it going to be positive or negative?
Positive!
How would a gram stain sample appear if the culture became contaminated?
If a gram stain sample becomes contaminated, it may show a mix of different bacterial cell types, complicating interpretation. For instance, if both gram-positive and gram-negative bacteria are present, the sample could display a combination of purple (gram-positive) and pink (gram-negative) cells. Additionally, the presence of extraneous cells or debris could obscure the true morphology of the target bacteria, leading to misleading results. Overall, contamination can significantly affect the clarity and reliability of the gram stain analysis.
Can a o positive woman and an a negative man have a o positive baby?
Yes, because when the too mix they can come out to anything
Do positive objects contain only positive charges?
No, positive objects can contain a mix of positive and negative charges. For example, in an atom, the nucleus contains positive protons while the surrounding electron cloud contains negative electrons.
What are the three basic Theories on the principle of gram staining reactions?
The gram stain is a basic differential stain used to determine if a bacterial cell is gram positive or negative. Gram positive cells have a thick peptidoglycan layer that will trap the crystal violet iodine crystalls and apear purple. Gram negative cells only have a thin peptidoglycan layer that allows the crystals to diffuse out of the cell and will only be seen with the application of a counterstain, such as safranin which turns the cells pink.
Is the product of 3 integers positive or negative?
Oh, dude, let me break it down for you. If you multiply three integers, the product will be positive if all three integers are either positive or negative. If you have two negative integers and one positive integer, the product will be negative. So, like, it depends on the mix of positives and negatives, you know?
Why do gram negative cells stain pink?
Gram negative bacteria actually stain red because they have a less complex cell wall than Gram positive bacteria and they are easily decolorised by the decoloriser acetone alcohol. Hence they take up the colour of the counter stain safranin which is red during the Gram staining procedure.
What is the plus and minus sign mean on a s10 Chevy?
Positive and negative electrical connections, mix those up and you will have problems.
If iodine step missed in gram stain what will happen?
Iodine (I - or I3 - ) interacts with CV+ and forms large complexes of crystal violet and iodine (CV-I) within the inner and outer layers of the cell. Iodine is often referred to as a mordant, but is a trapping agent that prevents the removal of the CV-I complex and, therefore, color the cell.[10]
Can liquid soap be used in salt crystal mix?
I Don't Think So Because Soap Doesn't Have Any Type Of Strong Positive Charge For It To React In A Chemical Mix. The Best Thing Is To See What Positive And Negative Charges Soap Has .
Can o blood father a child with a blood type?
it is rh negative and rh positive that u dont want to mix not the a b o types it is the + or - two ++ mom n dad or two -- mom n dad not 1 positive(+) and 1 negative(-)
