In a population of beetles, about 1 in every 6 beetles is slightly smaller and lighter in color than the others. the small, lighter beetles are a little better at evading predators and this increases the chances of survival and reproduction. what is likely to happen to the representation of the smaller, lighter beetle in the overall population over time? will the ration remain at roughly 6: 1, or will it change? if it changes, why will it change, and in what direction?

Which of the following is true about the introduction of a non-native species to an environment? (a) they usually adapt quickly so they can have a positive affect on the environment. (b) they can disrupt the environment and cause much damage and devastation to native species. (c) they usually become predators in a food chain and to keep prey populations under control. (d) because the native species are better-adapted to the environment, the non-native species always end up dying out.
