Enzymes are proteins that are biological catalysts
They reduce the activation energy required for a reaction to occur and thus speed up a reaction
Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)
They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's
They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.
They aren't used in the reaction so they're re-usable.
If it isn't one of these then it is not one of the properties of enzymes
Observation the action or process of observing something or someone carefully or in order to gain information:
Assessing aggregate exposure to a series of compounds with the same biological mechanism is called cumulative exposure assessment.
<h3>
What is cumulative exposure?</h3>
Because cumulative exposure evaluations evaluate exposure to numerous stressors via different pathways, they are referred to as "combined exposure assessments." Exposures to a single stressor are estimated using aggregate evaluations from different sources and pathways.
Cumulative evaluations portray real-world exposure more accurately, but they also provide an element of complexity not seen in typical exposure assessments , which evaluate stressors separately.

I'd say B, anyone disagree??
