A student weighs 29 apples and records the observations in the graph below. A bar graph with a heading that reads 'Masses of Apples.' The label for the x-axis reads 'Mass (kg)' and measures from 0 to 0.18. The label for the y-axis reads 'Number of Apples' and measures from 0 to 15. The coordinates for the bars on this graph are as follows: (0.10-0.12, 3), 0.12-0.14, 7), (0.14-0.16, 13), (0.16-0.18, 6). Based on the graph, it can be concluded that about one-tenth of apples weigh between 0.10 kg and 0.12 kg between 0.12 kg and 0.14 kg between 0.14 kg and 0.16 kg between 0.16 kg and 0.18 kg

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).
