Consider the food chain of grass → grasshopper → mouse snake → hawk. about how much of the chemical energy fixed by photosynthesis of the grass (100 percent) is available to the hawk? consider the food chain of grass → grasshopper → mouse snake → hawk. about how much of the chemical energy fixed by photosynthesis of the grass (100 percent) is available to the hawk? 1% 0.01% 0.1% 10%

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

"a.) well–developed vascular system."

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.
