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.
I would go with B & D because they change over time and they can go extinct like those big octopus in the oceans, they are rare to see in my opinion because they can blend in with other things that keeps them away from danger.
The statement that suggests that the shape of an enzyme determines its function, would be the fact that enzymes are specific to certain substrates, depending on the particular shape of an enzyme it can allow binding to specific substrates and allow for catalyzing that corresponding reaction.
Answer:
100 percent because all would result Pp and the (p) which is white and recessive allele would express only in absence of dominant allele (P)
I think its B but I'm not sure .. sorry
