Which is an example of a population?

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).

Which of the following would be the best hypothesis for this experiment? a) use of the ginko biloba extract improves clinical outcomes when administered to patients with t2d. b) ginko biloba improves clinical outcomes of diabetes patients when combined with metformin. c) diabetes in patients is worsened when ginko biloba is taken in conjunction with metformin. d)the use of ginko biloba to treat t2d in combination with metformin lowers the cost of t2d treatment. ginko biloba shows benefits against t2d when combined with plant extracts as compared to other treatments.
