Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.
In this case, the experiment suggests that the dose-response relationship is linear.
<h3>What is a linear effect?</h3>
A linear effect occurs when the independent and dependent variables are proportionally related during an experiment.
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.
