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.

Well if you placed the g facing you , it would look upside-down under a microscope , but if you faved it facing the other direction it would look as if it was facing you (the correct way)
Answer:
Since they need to float, leaves on the surface of plants are flat. 6. The presence of air sacs enables them to float. Their roots are smaller so water can spread freely and directly into the leaves
