1, 2nd Edition
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):
A) observation
B) hypothesis.
C) theory.
D) experiment.
E) None of the other answer options is correct.
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.

4. In the 1600s, Francesco Redi demonstrated that living organisms come from other
living organisms. However, it would be inaccurate to say that Redi supported his
hypothesis because:
A) his experiment only investigated a single kind of meat.
B) his experiment was done so long ago.
C) his experiment was based on observations.
D) his experiment only investigated a single organism.
E) his experiment didn't have the proper controls.

A)
Observation hypothesis formulation question experiment prediction
B)
Observation question hypothesis formulation experiment support or
refute hypothesis
C)
Observation question hypothesis formulation experiment prove or
disprove hypothesis
D)
Observation question experiment hypothesis formulation prove or
disprove hypothesis
E)
Observation question experiment hypothesis formulation support or
refute hypothesis
6. An explanation supported by a large body of observations and experimentation is
referred to as a(n):
A) prediction.
B) theory.
C) hypothesis.
D) supposition.
E) investigation.
7. Observations allow scientists to draw tentative explanations called hypotheses.
A) True
B) False
8. What is a hypothesis?
A) the same thing as an unproven theory
B) a tentative explanation that can be tested by experiments
C) a verifiable observation
D) an experiment that leads to a prediction
E) None of the other answer options is correct.
9. When carrying out a controlled experiment, it is important to:
A) change multiple variables at once to see the full effect of the variables.
Page 2

B) subject different groups to different conditions.
C) change only one variable at a time.
D) All of these choices are correct.
10.A hypothesis is considered a theory when the:
A) results of a single experiment support the hypothesis.
B) hypothesis has been revised many times.
C) results of several experiments do not support the hypothesis.
D) results of several experiments support the hypothesis.
11. Which one of the following is NOT part of the scientific method?
A) experimentation
B) observation
C) prediction
D) assumption
E) hypothesis
12. Asking and answering questions about the world in an unbiased manner is referred to as:

by spontaneous generation?

B) Redi
C) Pasteur
D) Darwin

as a(n):
A) variable.
B) control.
C) test group.
D) observation.
16. In some experiments, several identical groups are set up, keeping conditions similar
among them. In the group, a change is deliberately introduced. In the group,
this change is not introduced. In this way, the researcher can determine if the change has
an effect.
A) control; test
B) test; control
C) null; variable
D) variable; null
17. Which one of the following is NOT a way in which biology is typically approached?
A) biomechanics
