Write one similarity and one difference between skeletal muscle and cardiac muscle. me.

A similarity would be that they are both muscles. A difference would be cardiac muscle is only in the heart while skeletal muscle can be found throughout the body. Another similarity would be that they are both striated. Another difference would be that skeletal muscle is generally on conscious or voluntary control while the cardiac muscle is automatically used to keep your heart pumping

C) to ensure each new cell has an exact copy of the dna

Answer:

it provides an alternative energy pathway for the reaction to proceed.

explanation:

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.
