Carbon Plus Indicated by Arrows Natural Pur Anthropogenic Plus
The oceans absorb carbon through three processes that draw atmospheric carbon dioxide into the oceans: the physical
carbon pump, the biological carbon pump and the carbonate pump. In which scenario would a carbon sink be the
result of the physical carbon pump mechanism?
A
me
The movement of CO2 into and out of the ocean is fairly equal.

More more CO2 is diffusing out to the atmosphere than is diffusing into sea

More CO2 is diffusing into sea surface water than is diffusing from sea
surface water out to the atmosphere
More CO2 diffuses and dissolves in colder sea surface water and less CO2

Where can dna be found in a prokaryotic cell

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
