2. Which of the following is not an accurate statement about dose-response?

The NOAEL is the highest data point on the dose-response graph that produced an adverse effect.
The dose-response is used to establish causality between a compound and an effect
The bell shaped curve demonstrates individual variation in response to a particular dose
The shape and slope of the dose-response curve is extremely important in predicting the toxicity of a substance at specific dose levels.

3. The hallmark of a toxic response is that adverse effects are immediate. (Points: 3)

4. Please match the biomarker term with the appropriate item. (Points: 3)


Answer Potential Matches:
: A biomarker for exposure 1: Levels of dioxin measured in the bloodstream.

3: Levels of a protein which rises in the case of tissue damage

: A biomarker for effect
: A biomarker for susceptibility
