During the 1800s, seal hunters preferred dark-furred seals from natural seal populations. what effect would best describe what this did to the remaining seal populations over time?

The correct answer is stabilizing selection.

Explanation:

In case if the dark-furred seals, that is, the dark fur as the common phenotype are preferred from the natural seal populations, it shows the effect of stabilizing selection. A kind of natural selection, which encourages the mean values over the extreme ones is known as a stabilizing selection. It is in contrast to the disruptive selection, in which both the extreme values are favored.

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.
