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.
Above 120 miles (200 km) above sea level, temperatures in the thermosphere can vary between 600Â° and 2000Â°C (1100 and 3600Â°F). The actual temperature range is highly depe â¦ ndent on solar activity.A longer answer The thermosphere is a layer of Earth's atmosphere above the mesosphere. The thermosphere extends from 50 to 55 miles (80-90 km) above sea level, with the upper limit undefined.bove 120 miles (200 km) above sea level, temperatures in the thermosphere can vary between 600Â° and 2000Â°C (1100 and 3600Â°F).
