The crown-of-thors starfish is a particularly successful invasive species. It has several traits that lead to its proliferation on the Great Bamer Reef except that it eats a wide variety of foods
it breeds rapidly
it has no predators
it feeds on large quantities in a short time frame.

it should be all of them because it asks if you included all of those in your answer

explanation:

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
