Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?

Biology
1 answer:
rewona [7]3 years ago
5 0

Answer:

The rapid decolorization with ethanol or acetone

and counterstaining with safranin

When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple

Which of these is a part of good dental hygiene?
natka813 [3]
Yearly dental visits are a part of good dental hygiene because the dentist will check for cavities, fix them, clean your teeth very thoroughly (or whitening treatment), and check the progress and movement of your teeth. They can also recommend when dental surgery is necessary, for instance, if you have extra teeth that can be removed or when your wisdom teeth are coming in. Hope this helps! :)

Glucose enters the epithelial cells of the small intestine against its concentration gradient. Select the best explanation from
creativ13 [48]

Answer:

The correct option is this: GLUCOSE IS CO-TRANSPORTED WITH Na+, WHICH MOVES DOWN ITS CONCENTRATION GRADIENT INTO THE CELL.

Explanation:

The small intestine is the place, where digested food molecules are absorbed so that they can be transported into the living cells through the blood stream.  The glucose molecule is transported into the small intestine by mean of co-transport with sodium ions; this is an example of active transport. This form of transportation across the small intestines prevents the back flow of glucose molecules.
