12. The diagram below shows a process that affects chromosomes during meiosis. This process can be used to explain
the process of differentiation in offspring
the origin of new combinations of traits in offspring
why some offspring are genetically identical to their parents
why some offspring physically resemble their parents

well we can't tell you because we cant see the time give a screen shot or something.

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.
