(last question) #5
Describe the different body senses and how they function.

Those senses are sight, smell, hearing, taste, and touch. We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs, and interprets them to give us a sense of what's happening around us.

Explanation:

This is the best that I could do

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.
