Explain what is meant by a "pesticide treadmill" and why it is a concern to farmers and consumers.

Which of the following is the BEST test for the theory of natural selection?

  1. Which of the following is the BEST test for the theory of natural selection?
Using artificial selection to produce different breeds of dogs
Exposing a population of rapidly replicating organisms to selection that kills a large percentage over the course of many generations and then comparing the final generation to a population that was not exposed to the variable
Observing a group of rapidly replicating organisms for many generations and seeing if there was any change in their genes relative to the original population
Introducing chimpanzees to different social settings in order to see how their behavior can be changed

1.    How is artificial selection different from natural selection?

Artificial selection is the only kind of selection that can occur in a laboratory.
Artificial selection is selection by humans rather than the environment.
Artificial selection changes traits but not genes.
Artificial selection can occur over one or two generations as opposed to many generations.

1.    Polar bears from the Arctic do not produce offspring with the speckled bear of South America due to:

1.    Which of the following statements about the gene pool of a species is TRUE?

The gene pool is different in different individuals of the same species.
Every individual of a species carries part of the gene pool for that species in its chromosomes.
Every individual of a species carries the whole gene pool for that species in its chromosomes.
