Question 11

Match between columns
                        Premises: The introduction of a single species into a new environment produces rapid evolution of many new species.
Gene flow between species is restricted because their habitats are separate.
One species of plant has a long flower tube and can only be pollinated by bumblebees,whereas another similar species has short flower tubes and can only be pollinated by honeybees.
A plant arises within a population that has a different number of chromosome sets than other members of its population.It can self-fertilize but cannot interbreed with any other members of its population.
The sperm of one bird species cannot reach or fertilize the egg of a related bird species.
Geographic separation prevents interbreeding.
A population evolves into separate species when separated by a geographic barrier.
Courtship and mating displays keep organisms breeding within their own species.
Members of one species mate at dusk,while members of a closely related species mate at dawn.
Horses and donkeys can interbreed,but the mules that result are sterile.
Differences in anatomy,physiology,or behavior prevent interbreeding of closely related species.
Natural factors prevent interbreeding between closely related species.
