Sore throat is a symptom, not a disease. In each case, there was a different cause that dictated a different treatment. The scratchy throat probably was a mechanical problem caused by dry, heated winter air and aggravated by my friend's tendency to breathe through her mouth when she sleeps.
Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
Carbon Dioxide. Carbon Dioxide (CO2) is an important greenhouse gas, and most lakes act as net sources of CO2, releasing it into the atmosphere. Lakes also bury large amounts of carbon in their sediments, over three times more than the worldâs oceans.
