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 vs Anaerobic Bacteria. There are two types of organisms and tiny single-celled bacteria called aerobic and anaerobic bacteria in the human body. Aerobics are able to use oxygen, whereas anaerobic bacteria can sustain itself without the presence of oxygen.ndividual human cells are also facultative anaerobes: They switch to lactic acid fermentation if oxygen is not available. Summary: 1. Aerobic bacteria inhales oxygen to remain alive. 2. Anaerobic bacteria dies in the presence of oxygen, and therefore avoids O2.
