Question

I need help on this question in biology and biology is hard and confusing

Answer 1

Answer:

The answer is b

Explanation:

The answer is b because if you want something to die out then they obviously have to stop reproducing in order to do this you have to stop breeding with them.

Answer 2

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

1. Habitat isolation: Two species occupy entirely different and distant habitats.
2. Temporal isolation: Two species  procreate at different times of the year.
3. Behavioral isolation: Two species exhibit different mating behaviors.
4. Gametic isolation: The gametes of the two species cannot fertilize.
5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
