false
true
rewatch

Explanation:

In experimental design, especially in fields like biology, chemistry, or medicine (natural science subfields), different experimental groups can be assigned different concentrations of a treatment (e.g., drug, chemical, nutrient) to test the effect of varying doses. This is a common practice in experiments to determine dose - response relationships or compare the efficacy of different levels of the treatment. So the statement is true.

Answer:

True
