the organization of organisms has increased in complexity throughout time. in light of this trend, which of the following is true?
a. as organisms increase in complexity, the entropy in the surrounding universe correspondingly increases.
b. the increase in organism complexity is a function of evolution, not thermodynamics.
c. each organism is considered a closed system, and therefore increased organism complexity has no relationship to the laws of thermodynamics.
d. organisms increase in complexity to maintain homeostasis with the decrease in entropy of the surrounding universe.

i think the answer is 95 hope this

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.
