Explanation:
Gram staining is a widely used technique designed to distinguish between the bacteria on the basis of the composition of the cell wall of the bacteria.
The basis of differentiation is the color of the bacteria they attain after staining technique is performed that is gram-positive bacteria remain deep blue in color while gram-negative bacteria appear pinkish-red in color.
If the culture of the bacteria on which the test to be performed is of more age that is more than 24 hours of age then the bacteria cells lose their ability to retain the stain mainly the gram-positive bacteria. Also, the culture gets damaged after 24 hours.
Thus, fresh cultures are used for staining.
We depend on those fuels to heat our homes, run our vehicles, power industry and manufacturing, and provide us with electricity.
Explanation:
<h2>Yeast is used for the leavening of bread. Yeast uses the sugars and oxygen in dough to produce more yeast cells and carbon dioxide gas. This is called multiplication. The carbon dioxide makes the dough rise which gives the bread a light and spongy texture.</h2>
The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori,[1] refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.[2]
Answer:
Explanation:
In this specific scenario, seeing since both of the mediums are differential, the bacteria can grow on either of them, therefore either of them would be a good choice. A differential media allows the researcher to visually distinguish which species have the specific biochemical process. Which in this case both options have the ability to allow bacteria to grow which is what is needed.
