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 lies between the exosphere and the mesosphere. âThermoâ means heat, and the temperature in this layer can reach up to 4,500 degrees Fahrenheit. If you were to hang out in the thermosphere, though, you would be very cold because there arenât enough gas molecules to transfer the heat to you. This also means there arenât enough molecules for sound waves to travel through. This layer of Earthâs atmosphere is about 319 miles (513 kilometers) thick. Thatâs much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. The thermosphere is home to the International Space Station as it orbits Earth. This is also where youâll find low Earth orbit satellites.
