Which of the following is the correct order of events in mitosis? no, that's not the correct answer. a. sister chromatids line up at the metaphase plate. the kinetochore becomes attached to the mitotic spindle. the nucleus reforms and the cell divides. cohesin proteins break down and the sister chromatids separate. b. the kinetochore becomes attached to the mitotic spindle. cohesin proteins break down and the sister chromatids separate. sister chromatids line up at the metaphase plate. the nucleus reforms and the cell divides. c. the kinetochore becomes attached to the cohesin proteins. sister chromatids line up at the metaphase plate. the kinetochore breaks down and the sister chromatids separate. the nucleus reforms and the cell divides. d. the kinetochore becomes attached to the mitotic spindle. sister chromatids line up at the metaphase plate. cohesin proteins break down and the sister chromatids separate. the nucleus reforms and the cell divides.

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).
