As unique as the word suggest, stem cells are predominantly termed as a certain class of uniform cells which have the characteristics of being differently able into specialized cell types. Mostly stem cells are described as stable at the natural level and separate (through mitosis) to create numerous similar cells. Although, most warm-blooded have two different types of stem cells they can also be found in multicellular living bions.
Microorganisms, the tiny living creatures, that dwell in every niche, occupying an area greater than us behemoths, are highly valuable. An appreciable proportion of our body weight results from our direct association with them. Their mere presence is capable of preventing a number of diseases and an alteration in their proportions may cause an illness.
