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.
This is, in essence, what goes on behind a demand curve. Above you see an example of a demand schedule. It shows us how many units (quantity) of a good will be demanded at a given price. The above schedule gives us a linear demand curve, because for every $10 the price goes up, quantity goes down by 20. We can use this schedule to plot the following points on a graph. Since we know that the curve is linear, we can just connect these points to get our demand curve (we could also connect the points if it wasnât linear, it just wouldnât be as exact).
