The opposite can be true; i.e., people with large muscle mass sometimes have elevated CK levels in the absence of any pathology. This particular enzyme falls into a category where an individual's own normal is more relevant than the normal range given for a population.
1 If the demand increases, and the supply remains the same, there will be a shortage. 2  This will mean the price will increase. 3  If the demand decreases, and the supply remains the same, there will be a surplus. 4  This will mean the price will go down.
At a price higher than equilibrium, demand will be less than 500, but supply will be more than 500 and there will be an excess of supply in the short run. Graphically, we say that demand contracts inwards along the curve and supply extends outwards along the curve.
