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 is the sixth element in the periodic table. Located between boron (B) and nitrogen (N), it is a very stable element. Because it is stable, it can be found both by itself and in many naturally occurring compounds. Scientists describe the three states of carbon as diamond, amorphous, and graphite. It is the same graphite you find in pencils.
