Dr. mitchell is a scientist studying heredity. she wants to isolate the basic unit for the transmission of heredity, which is a(n)

The answer in the space provided is gene which is a unit of hereditary, this is being transferred or it is having to be passed down by parents to their child in which will contribute to the child’s characteristics and even behaviors.

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.
