The process where a specie develops and evolves into new many species is termed as speciation. Macroevolution explores the mechanism of speciation where organisms across biological populations evolve as distinct population.
There are many causes to speciation, a) geographic isolation, b) gene flow reduction, and c) reproductive isolation.

Answer: The correct answer would be option a.
Explanation:
The hemoglobin in red blood cell has a tendency to bind to oxygen as well carbon dioxide in a reversible manner. It depends upon the partial pressure of the gas.
For example, at tissue site, the concentration of carbon dioxide is higher than oxygen due to which the affinity of hemoglobin increases for carbon dioxide.
In hemoglobin, carbon dioxide reacts with water to form bicarbonate ions and hydrogen ions.
At alveolar site, these ions again convert into carbon dioxide and excrete out of the blood as a part of exhale air.
The answer is D.) the process where distribution of molecules is balanced out by their movement.
