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.
If demand goes up and supply stays the same then you will have shortages because enough goods aren't being produced. Prices may then go up to reduce demand and reach a new equivalence point. Conversely if you have low demand and high supply pricess will be lower to increase demand and get rid of excess product.
