There is a huge amount of carbon stored in permafrost. Right now, the Earth's atmosphere contains about 850 gigatons of carbon. (A gigaton is one billion tons—about the weight of one hundred thousand school buses). We estimate that there are about 1,400 gigatons of carbon frozen in permafrost. Ok bye
I think the answer is A Explanation- :)
It is a mixture.
take salt water for example if you boil the water the salt will be left behind. salt water on its own is not a pure substance a pure substance would be just the water by its self.
hope that helps.
The correct answer here is C. A molecule that has both polar and
nonpolar regions is called ampipathic. The polar end of the molecule is
water-loving, or hydrophilic, and the nonpolar end of the molecule will
be water-repelling, or hydrophobic. This means the molecules are able to
connect both to other water molecules, and to molecules of other
substances.
