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

Explanation:
the moon would have to be closer to the earth for it to perfectly align with the sun, or if it were smaller it would look like a circle with a smaller black circle in the middle.
I’d say B is the best choice

Answer:
Convergent Evolution
Explanation:
Convergent evolution is the development of similar traits, across many lineages by plants and animals who originally do not have these traits but developed them because of the biome that they find themselves. Carnivorous plants are examples of living things that have undergone carnivorous evolution.
Plants lacking in Nitrogen have undergone carnivorous evolution for up to seven lineages. Sundews for instance have developed flypaper traps, a carnivorous property that helps them trap insects that they eventually digest.
