1. Hypotheses can only be tested by doing experiments.
A) True
B) False
2. Let's say you feel very strongly that cigarette smoke does not increase the probability of
getting cancer, and you base your view on something you read on the Internet. This is a
good example of a(n):

3. Many salmon return to the place where they were born to lay eggs. You hypothesize that
they use visual cues to find their way back. To test your hypothesis, you blind salmon
and then examine whether or not they are able to return to their birthplace. You find that
they are unable to find their way back. From this experiment, you:
A) have proved your hypothesis.
B) have rejected your hypothesis.
C) supported your hypothesis.
D) can't determine whether your hypothesis is supported or not.
E) developed a theory about the role of vision in salmon navigation.

C) his experiment was based on observations.
D) his experiment only investigated a single organism.

A) variable.
B) control.
C) test group.
D) observation.
16. In some experiments, several identical groups are set up, keeping conditions similar
