Because of sport hunting and the draining of marshlands, the size of the whooping crane population reached a low of 16 individuals in 1940. Since then, conservation efforts have been put in place to increase the whooping crane population size. Which of the following actions would most likely increase the size of the whooping crane population with the
least impact on the ecosystem?
O A. Introducing new insect species for whooping cranes to eat
B. Eliminating all wild predators in the whooping crane's habitat
C. Establishing protected areas for whooping crane breeding and migration
D. Counting whooping crane opulations by tagging and releasing individual birds

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

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.
