Search any microbiological text book and you will see that there are thousands of different types of bacteria in the world, everywhere around us, although only about two thousand species of bacteria have actually been identified. On the most part, bacteria simply share the world with us and are of no specific harm to any human being. They are remarkable organisms for their simplicity of form, their efficiency of life and their rapid ability to reproduce. It has been said that it is possible for some species of bacteria, within the correct environment, to reproduce themselves in the span of about twenty minutes, although most do not reproduce quite so rapidly. . As far as we know, bacteria have been present upon the earth for billions of years and are generally considered...

Environmental Hazards What are toxicants and how do they affect living organisms? According to Dr. Celine Godard, toxicants and toxins both reference substances that are toxic; however, toxins are made in nature (like in poisonous mushrooms or in the poisonous venom that snakes use to kill their prey) and toxicants are human made (Godard, et al., 2001). Examples of toxicants would be "industrial waste products and pesticides" -- along with pollutants that
Wells uses the idea of violence as a catalyst to explain human behavior and thinking. Violence seems the perfect solution throughout "The War of the Worlds" and regardless of how they look at the problem, both the Martians and people believe that by using violence they are probable to experience victory. However, when considering that the Martians' superior technology is not enough to provide them with the opportunity to be
