The range of the radar horizon dependson the height of the antenna and on the amount of bending of the radar wave.The bending is caused by diffraction and refraction. Diffraction is a propertyof the electromagnetic wave itself. Refraction is due to the prevailingatmospheric conditions.
Anaerobic bacteria, or anaerobes, are bacteria that do not need oxygen to live. In humans, these bacteria generally live in the gastrointestinal tract, but they may also be found in other places outside the body, including in the soil and water, in foods, and in animals.
Aerobic And Anaerobic Bacteria. Anaerobic Bacteria. The first and most common bacteria would be the anaerobic bacteria, Obligate Anaerobes. They are capable of living in places void of O2 and most will die in the presence of oxygen. Some agile bacteria are Facultative Anaerobes. These are able to live both in and out of an oxygen laden atmosphere but they are rare microbes. Clostridium, for example, is one bacterial genes that does not need oxygen to survive. Everyoneâs smelled anaerobic decomposition inside the refrigerator on occasions.
