Answer:

The cell has different parts, and those that can absorb stains or dyes are referred to as chromatic. Having absorbed the stain, these parts of the cell become more visible under the microscope and can therefore be easily distinguished from other parts of the same cell.

Without stains, cells would appear to be almost transparent, making it difficult to differentiate its parts.

Explanation:Methylene blue has a string affinity for both DNA and RNA. When it comes in contact with the two, a darker stain is produced and can be viewed under the microscope

What specifically is this biochemical used for, and how is it broken down during digestion?
Cerrena [4.2K]
Digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas.

If a body's rectal temperature cannot be taken, what other location can be used?
natali 33 [55]
The armpit isn't the most precise but it is close. Under the tongue, across the forehead, as long as you have the proper tools (thermometer, the thermometer meant for foreheads) you should get a fairly accurate reading.
