This is called dehydration. Laboratory tests may be done on the food or a stool sample to determine what germ is causing your symptoms. However, these tests do not always show the cause of the diarrhea. Tests may also be done to look for white blood cells in the stool, a sign of infection.
Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. The boundary between the thermosphere and the exosphere above it is called the thermopause. At the bottom of the thermosphere is the mesopause, the boundary between the thermosphere and the mesosphere below.lthough the thermosphere is considered part of Earth's atmosphere, the air density is so low in this layer that most of the thermosphere is what we normally think of as outer space.

Best Answer: The thermosphere has a high temperature, because the smalll amount of oxygen present is heated up rapidly by solar radiation, causing the molecules to move about rapidly (temperature is the measure of the average kinetic energy of the molecules).emperatures climb sharply in the lower thermosphere (below 200 to 300 km altitude), then level off and hold fairly steady with increasing altitude above that height.
