Multiple Choice

Identify the letter of the choice that best completes the statement or answers the question.

____1.Hawaiian honeycreepers are a group of birds with similar body shape and size. However, they vary greatly in color and beak shape.

b. / cross-pollination / d. / convergent evolution

____2.The flying squirrel of North America closely resembles the flying phalanger of Australia.

b. / eating the insecticide caused the bugs to become less resistant to it
c. / it destroyed organisms that cause disease in the insects, thus allowing them to live longer
