How do environmental factors influence genetic traits? a. environmental factors determine all genetic traits. b. environmental factors can determine if a genetic trait becomes a health issue. c. environmental factors are determined by genetic traits. d. environmental factors have no influence on genetic traits.

B. Environmental factors can determine if a genetic trait becomes a health issue

Explanation:

Genetic traits are the representation of genetic codes (our DNA). It is like a very big library which contains lots of information, some more available,some less available. The environment we where born and we live in, can determine if the information of this library, the genetic codes, are represented in traits.

For example, if there is someone who has one or several familiars who have suffer of Diabetes, this person will tend to have the same condition, depending a lot on his or her habits. If this person does not take care of him or her self with what he or she eats and has a sedentary life (environmental factors), the person will be more likely to have diabetes.

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.
