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.
Explanation:
Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. Polymers are chains with an unspecified number of monomeric units. a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.

Plasma contains proteins (to help blood to clot), and it transports substances through the blood stream. The plasma also contains glucose and other dissolved nutrients. It can also carry water, salts, and enzymes. Plasma has a very light yellow color, such as the color of straw.
