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.
The ocean surface currents circulate counter clockwise direction in the southern hermisphere duebto the coroilis effect.
0-4 degrees Celsius, below which bacteria grow very slowly. This is the same as refrigerator temperature.

Answer:
True
Explanation:
In a capitalist society, the poor make up the working class that is exploited through their work, generating income and profits for businessmen and tycoons, who continue to get rich and have their needs and desires completed and complemented by the work that the poor perform.
With this, we can confirm that within the capitalist society, wants are often supplemented for the poor, but only the wants of the rich and powerful, the wants of the poor end up being suppressed and often left aside.
