Question

Which of the following statements is false?

a) A dose-response curve shows the effect of different doses on a population.
b) Doses lower than the threshold level will have no measurable effect on organisms.
c) The smaller the LD50, the more toxic the chemical.
d) A dose-response curve is a graph illustrating the inverse relationship between LD50 and the acute toxicity of a chemical.
e) The threshold level for a dose-response is the minimum dose with a measurable effect.

Answer 1

d) A dose-response curve is a graph illustrating the inverse relationship between LD50 and the acute toxicity of a chemical.

This statement is false because a dose-response curve is a graph illustrating the relationship between the dose of a drug or chemical and the effect it has on an organism or a population, not specifically related to LD50 or acute toxicity.
