8. This question is based on the following passage. Both Seagulls and wild geese are large birds. They're also similar in that both kinds of birds can fly over great distances. On the other hand, seagulls are
scavengers, while wild geese aren't. Seagulls, for example, are often found around garbage dumps. Geese, however, feed on things like seeds and insects.
Another important difference between the two kinds of birds is that geese fly on long annual migrations of well over 1,000 miles. Seagulls will migrate far inland
to search for food. However, they don't follow seasonal patterns of migration like wild geese.
Clue words showing that contrasts are being made in this paragraph include
A. both and difference.
B. while and however.
C. also and hand.
D. and and similar.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
