Sarah wants to know how many iguanas live on the island of St. Thomas. She sets up
traps for them, and in the initial trapping event, she captures and marks 42 iguanas.
Three months later, she sets out traps again and this time she captures 35 iguanas, 9
of which had the mark. What is the population size of iguanas on St. Thomas?

explanation:

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.

answer; an inhibitory postsynaptic potential;

i'm thinking 600 feet deep in one of the finger lakes.
