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.
For example, if the price of the product is $10, the quantity demanded will be 100. As price increases to $20, demand will fall to 50, and when price further increases to $30 demand will fall to 25. Plotting these points on a graph will show a downward sloping demand curve from left to right.
