A biologist analyzes the DNA sequences in three different primates. The biologist finds that primates A and B have nearly identical DNA sequences. The DNA sequences in primate Care significantly different from those of primate A.
From this information, the biologist may infer that
O primates A and B are more closely related to each other than either is to primate C.
O all three primates appeared on Earth at about the same time.
O either primate A or primate B must be a direct ancestor of primate C.
O primate C must have been the ancestor of both primate A and primate B.

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).
