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.
Summary: 1. Aerobic bacteria inhales oxygen to remain alive. 2. Anaerobic bacteria dies in the presence of oxygen, and therefore avoids O2. 3. Aerobic respiration produces energy with the help of a complex process in the cells. 4. Anaerobic respiration produces crystals, and causes pain in muscled areas.
