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.
1 However, carbon from this reservoir is exchanged extremely slowly with the carbon in the ocean and atmosphere. 2  Among this large reservoir there are also about 4000 GtC in the form of fossil fuels (oil, coal and natural gas).
