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.
Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5 C with each increase in altitude of 1 kilometer (about 3.6 F per 1,000 feet).The rate at which the temperature changes with altitude is called the lapse rate.n the layer above the troposphere, the stratosphere, temperature rises with increasing altitude. In the stratosphere, the air is heated from above by ultraviolet light which is absorbed by ozone molecules in the air. The tropopause is the boundary between the troposphere (below) and the stratosphere (above).
