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.
Table 2.1 gives the distribution of carbon between the major reservoirs. For the atmosphere a few different values are given, referring to the likely pre-industrial content of the atmosphere, the accurately known values for 1959, when careful measurements began and the most recent data from 1980.
