Whereas Earth has only one satellite (aka. the Moon), Mars has two small moons: Phobos and Deimos. And whereas the vast majority of moons in our Solar System are large enough to become round spheres similar to our own Moon, Phobos and Deimos are asteroid-sized and misshapen in appearance.
Microorganisms, like certain bacteria and yeasts, living on the human skin or in the nose, mouth, throat, small and large intestine and vagina, are part of the normal human flora; they prevent overgrowth of harmful microorganisms. Some of these microbes, when overgrow, may become pathogenic, though.
Previously, different types of microbes and the ways they reproduce were discussed. Some microbes are free-living organisms and others are parasites. Even though the words 'microbe' and 'bacteria' are associated with disease for most people, not all microorganisms are 'bad guys'.This topic looks at the interactions between microorganisms and the human body.ome microbes are free-living organisms and others are parasites.
