Ascientist has been tracking and studying a population of deer in yellowstone national park. he surveys the population every six months. usually, the population is thriving and has a gene pool with a wide variety of traits. but during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. which of the following is most likely the event that occurred to change the population?

a)yellowstone national park expanded its borders.
b)a population of wolves was introduced into yellowstone national park.
c)the amount of disease in the deer population decreased.
d)more grass and shrubs were planted in yellowstone national park.

B) A population of wolves was introduced into Yellowstone National Park.

Explanation:

This is the most likely event that occurred to change the population. If the genetic variation of the population of deer was reduced significantly in such a short amount of time, then it is most likely due to the fact that a lot of deer died. This could be caused by many factors. Out of the options, the most likely catalyst for this would be that a population of wolves was introduced into Yellowstone National Park.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
