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:
The correct answer is option b. "the citric acid cycle".
Explanation:
The citric acid cycle is one of the most important pathways of the cellular metabolism because of its role in energy production and biosynthesis. The citric acid cycle is where most of the CO2 from catabolism is released. This happens by the release of two molecules of CO2 per turn in the cycle, using the two atoms of carbon from acetyl CoA.
A statement that carbon is matter and cannot be created or destroyed is an example of part of a scientific theory and is denoted as option A.
<h3>What is a Theory?</h3>
This term refers to series of principles which helps to explain a particular phenomenon.
The most suitable choice will therefore be option A as it helps to explain why carbon can't be created or destroyed due to it being a matter and is the correct choice.

Explanation:
Answer: The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
