Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
It is the central nervous system that takes charge of the body's involuntary functions outside conscious awareness. It is this system that is responsible for all of the body's involuntary acts, such as breathing, blinking, etc.
Carolus Linnaeus recognized the vital role of the internal environment and suggested that objective of mechanisms within the body is to preserve the constant conditions of the internal environment.
He was later known as the creator of current modern system of naming animals called binomial nomenclature
