Problem: When measuring the tissue response to a concentration of agonist added discretely, you measure from: Select one: the baseline prior to the addition of that concentration of the drug and express it as "change in g tension" 0g and express it as "g tension" the resting tension at setup and express it as "g tension" the tension achieved after washing and express this as "change in g tension" the baseline tension prior to the addition of the first concentration of the drug and express it as "change in g tension"
