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.
Answer:
Taxonomy- The science of naming and classifying organisms based on structural comparisons and genetic evidence.
Explanation:
Answer:
Gallbladder Shoulder Pain
Explanation:
Inflammation of the gallbladder, liver and pancreas occurs when gallstones develop in our body . Pressure on different types of nerves is produce when these organs develop inflammation. One of this nerve, the right phrenic nerve can travel upward towards the shoulder and upper back. When you apply pressure to the right phrenic nerve, it produces pain in the right shoulder. This is the reason why many medical resources acknowledge that right shoulder pain is one of the primary symptoms of a gallbladder attack.
