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.
The thermosphere has extremely high temperatures, coinciding with the prefix in its name, thermo, which means temperature. Temperatures can reach over 3,600 degrees Fahrenheit, and the high heat comes from the intense light rays, or radiation, from the sun. Since there is little to no atmospheric gases above the thermosphere, there is no absorption of the heat from solar radiation, and so temperatures soar. In lower layers of the atmosphere, as you increase in altitude, temperature decreases The thermosphere is the first layer to which this pattern does not apply. Ã
