A laboratory study using rats showed a steady increase in physical effects as the concentration of a toxic substance in their food was increased. This suggests that:.

Answer 1

In this case, the experiment suggests that the dose-response relationship is linear.

In this case, the doses are linearly (proportionally) related to the response of the individuals (rats).

The linear effects are very common in experimental procedures and nature as well.
