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.
In many ways, the thermosphere is more like outer space than a part of the atmosphere. Many satellites actually orbit Earth within the thermosphere! Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. Temperatures in the upper thermosphere can range from about 500Â° C (932Â° F) to 2,000Â° C (3,632Â° F) or higher. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere.
