Match the following. match the items in the left column to the items in the right column. 1. foreshocks process used to locate the epicenter of an earthquake 2. magnitude newer magnitude scale that measures the amount of moved (displaced) rock along a fault to determine the strength of an earthquake 3. mercalli intensity scale measure of the total amount of energy released during an earthquake 4. moment magnitude scale areas on active faults where a major earthquake hasn't occurred in a long time 5. richter scale mini-quakes that usually occur before a major earthquake 6. seismic gaps scale that measures the effects or severity of an earthquake 7. triangulation scale of magnitude based on the size of seismic waves produced by an earthquake

Describe the function of the endomembrane system? what organelles are involved?

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).
