. A class of environmental science students decided to determine the composition of trees in a forest next to their campus. The students decided to conduct a point-quarter survey. When they reached the study area they found that the east side of the woods was thick with blackberry bushes. The bushes had a lot of thorns and were difficult to maneuver around. The students decided to move to the west side of the woods to do their survey. What is wrong with this scenario

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).
