Tobacco products have been identified as mutagens. however, some tobacco users develop cancer and some do not. the reason for this apparent inconsistency is

some people are more predisposed to developing cancer when exposed to mutagens

Explanation:

Cancer predisposition is a term that means that an individual is more likely to develop cancer during his or her life due to genetic and other factors. Usually these individuals have relatives who have had some form of cancer and know that there is a greater possibility that they have too. This is not to say that cancer-prone individuals will have cancer someday, only that the chances of getting the disease are higher.

People predisposed to cancer are more likely to develop cancer when exposed to mutagens and this is a likely reason to explain why some tobacco users develop cancer and others do not.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
