Did you know?
WebNon-threshold dose-response curves indicate that the response to a toxicant is directly proportional to the dose, meaning that higher doses of the toxicant will produce a stronger response, while lower doses will produce a weaker response or no response at all. Therefore, non-threshold dose-response curves suggest that even small doses of a ... WebThe dose-response curve normally takes the form of a sigmoid curve.It conforms to a smooth curve as close as possible to the individual data points. For most effects, small doses are not toxic. The point at which toxicity first appears is known as the threshold dose level. From that point, the curve increases with higher dose levels.

WebStep-by-step explanation. 1. a. Highest potency is of substance A (therapeutic effect) because potency is related to dose. If the response of drug come in less dose then it is more potent. So in DRC the most left curve have highest potency. b. NOEL - No observed effect level. NOEL range of substance B is 1-5.
