Question

Which of the following is proportional to the dose in a Graded dose response scale?

(a) Intensity of the effect

(b) Color of the effect

(c) Concentration of the effect

(d) Toxicity of the effect

The question was posed to me in an international level competition.

The doubt is from Dose in chapter Environmental Impact of Pollutants and Analysis of Dose – Effect Relationship of Environmental Biotechnology

Answer 1

Right option is (a) Intensity of the effect

The best explanation: In Graded dose response curve which shows effect on a continuous scale, the Intensity of the effect is proportional to the dose. Response vs dose on x-y plane respectively shoes curve on a continuous scale whereas, Color of the effect, Concentration of the effect and toxicity of the effect is independent of the same.
