Acid fast stain is used to stain the bacteria of the genus Mycobacteria, because they contain large amounts of impermeable wax-like sbstances, which do not allow gram stain to penetrate the cells. Gram stain however, can penetrate the other bacteria with varying amounts of polysaccharides and lipopolysaccharadies in their cell walls, and thus can differentiate between them, For Acid fast stain, it would be difficult to differentiate between the gram positive and negative cells, and therefore, it is not used for this differential purpose, but to identify the Mycobacterim only.
Answer:
Cancer cells are the cells that divide rapidly than any other cells in the body. The drugs used in chemotherapy work on rapidly dividing cancer cells. Some cells of our body apart from cancer cells also divide rapidly along with the cancer cells such as the cells that line the stomach and the digestive tract. Chemotherapy drugs cannot differentiate the cancer cells and the normal cells so these drugs also attack the normal cells which divide rapidly along with the cancer cells. The drugs also attack the cells that are present in the roots of the hair. So, this results in the hair loss. Hair loss does not occur immediately after the chemotherapy treatment instead it starts after few treatments. The degree of the hair loss after chemotherapy depends on the drug type and process. So when the chemotherapy drugs are used it results in the hair loss and nausea.
Therefore, when chemotherapy drugs attack normal cells including the roots of the hair instead of cancer cells that divide rapidly along with the cancer cells it results in the hair loss and nausea.
Answer:
It is an everyday life theory because it is not supported by evidence.
Explanation:
This is something not supported by evidence there were no humans around to tell us today from way back then.
Dog breeding has breeders choosing the best dogs to use for breeding, so they are artificially creating an environment for breeding to occur. This is opposed to letting them breed naturally, which may produce unfavorable results.
