While on a camping trip, Brian collects a white tadpole from a pond and takes it home. The tadpole develops into a white bullfrog. When the frog gets too big, he releases it into a local pond. The next year, several white bullfrogs are observed in the pond. This is an example o

This is an example of gene flow.

Explanation:

Notice that Brian did not release the frog in its original pond, but in a local one. Gene flow or gene migration can be described as the transfer of genetic variation from one population to another. It is an important way to transfer genetic diversity between different populations, and it usually takes place through the migration of members of a population. In this case, the frog did not migrate by itself, but was taken by Brian instead.

yes, since there is a positive and a negetive if the positive and negitive wasn't there wouldn't a flow electricity in it.
