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.
A carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorb.Forests, soils, oceans and the atmosphere all store carbon and this carbon moves between them in a continuous cycle. carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorb.
