+ A type of algae can live in a salt marsh or in a
mangrove habitat. Scientists discovered that
the mangrove variety has higher levels of
chlorophyll when compared to the salt marsh
variety. Based on this finding, which statement
describes the most likely outcome?
A. The mangrove habitat will have reduced
amounts of atmospheric carbon dioxide.
B. The salt marsh variety will photosynthesize
faster than the mangrove variety.
C. The mangrove variety will photosynthesize
faster than the salt marsh variety.

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).
