Osmosis is taking place when water molecules move in all of the following situations except when a). water moves into the cells of limp lettuce leaves that are soaked in a bowl of water b).water moves out of a strawberry cells after sugar has been sprinkled on the berries c).water moves to an area of lower concentration between sugar molecules in the bottom of a beaker d).water moves between blood cells and blood plasma as a persons hydration level changes

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).

Why did adult crab numbers decline in he ecosystem, even though sea stars were still available?

Stem cells found adult tissue such as in bone marrow brain muscle skin and liver are only capable of what
