If interbreeding within the hybrid zone of the mountain pass decreased over time, what would you expect to happen to the Western and Eastern deer populations?

The two population will become separate species due to allopatric speciation

Explanation:

Allopatric speciation is also known as geographic speciation. In this speciation two populations of the same species isolated geographically from each other which prevents gene flow between them and the two populations evolve separately and over time, it leads to the creation of a separate species.

So here as interbreeding within the hybrid zone of the mountain pass decreased over time so it will lead to speciation in these populations and they will evolve into two separate populations due to lack of gene flow as a result of geographical isolation.

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.
