Personally, I believe the information helps.

Explanation:

Without this information the virus would not be contained, we would not have done research, taken samples, tested out the virus, or even attempted to contain it. With this information we can attempt to prevent a break out of the disease again. This is my personal opinion though.

Which is allopatric and which is sympatric
Helen [10]

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.

However, most of those eggs doesn't survive, and little frogs are never born in that case. This is why it has to have a lot of eggs so as to ensure that a decent number of offspring survives so as to continue the species.</span>
