    There are three types of environments in which cells are located which include isotonic, hypotonic and hypertonic. In an isotonic environment, the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell, the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of water on the outside of the cell and a high amount of solute inside the cell, water will be drawn inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment, water will leave the cell, as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth, although some live in slightly hypotonic solutions. (Alonzo, 2008)…

    In today’s world, many people have a very negative connotation when they hear the word “bacteria”. Bacteria have been the cause to many diseases, however bacteria do have some benefits and uses. There are thousands and thousands of different types of bacteria in the world and one group of bacteria, Gut Flora, has become evident in the bacterial community for being beneficial. Gut Flora is a group of bacteria that consists of microorganisms that live in the digestive tracts of animals. A healthy adult has around a trillion microbes of these bacteria in the gut. These bacteria have a vital role in the body and without them people probably would not survive. It is essential that people take care of their gut flora because a damaged gut flora has been the main cause of many diseases. Despite the fact that gut bacteria may have some harmful effects on humans and animals, the existence of gut bacteria within the intestinal tract result in the gain of many benefits for the bacteria and the host.…
