Answer:
a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures
Explanation:
This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
For example, Galapagos finches are isolated from others by the ocean (geographic isolation). Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
Many reasons. Some bacteria are able to thrive under extreme conditions, have the ability to reproduce asexually, or have a variety of metabolic processes.

Increased risk of Type 2 diabetes and heart disease is a common health consequence of lack of physical activities and Exercises.
<h3>Physical activities and Exercises.</h3>
