A. Dead animals will smell until they are completely decomposed or until they are dried out, whichever comes first. It goes without saying that the larger the animal, the more biomass there is to rot, the stronger the smell will be, and the longer the smell will last.
When cells are damaged by disease or injury, large amounts of these leak out, causing blood tests to show that enzymes are elevated above normal. (You can roughly compare this situation to a car that's leaking oil. Leaks in many parts of the engine can have the same result: oil all over your driveway.)
Blood serum concentrations are much lowerâonly about 0.4% of the body's potassium is found in blood serum. As noted above, hypokalemia can be caused by the sudden uptake of potassium ions from the bloodstream by muscle or other organs or by an overall depletion of the body's potassium.
