When a standard curve whose x-axis is this quantity is not hyperbolic, Furchgott's method may be used. The base-10 logarithm of a ratio of two values of this quantity appears in the Gaddum equation, which is used to generate Schild plots. In some calculations, this quantity is multiplied by one fraction called the “salt factor” and another fraction denoted capital F. “Loading” values of this quantity are proportional to the volume of distribution, while “maintenance” values are proportional to the (*) clearance. Curves that correlate this quantity with a “response” can measure the “median effective” value of this quantity, which is large when bioavailability is poor. The value of this quantity that kills 50% of subjects is denoted LD50. Paracelsus said that “the poison” is “made by”, for 10 points, what amount of a drug given to an organism? ■END■
ANSWER: dose [accept dosage; accept answers indicating the logarithm of the dose; prompt on answers indicating the amount or concentration of a drug or poison by asking “what is the formal term for that?”; prompt on concentration or amount alone by asking “the concentration of what?”]
