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.
Solar activity strongly influences temperature in the thermosphere. The thermosphere is typically about 200Â° C (360Â° F) hotter in the daytime than at night, and roughly 500Â° C (900Â° F) hotter when the Sun is very active than at other times.Temperatures in the upper thermosphere can range from about 500Â° C (932Â° F) to 2,000Â° C (3,632Â° F) or higher.The boundary between the thermosphere and the exosphere above it is called the thermopause.
