Science differs from other disciplines, such as history and the arts, because science relies on
facts
testing explanations
observations
theories
Measurements made while observing a plant grow 3 cm over a two- week period are called
inferences
variables
hypotheses
data
Based on your observations, you suggest that the presence of water could accelerate the growth of bread mold. This is
A conclusion
A hypothesis
An experiment
An analysis
Suppose that a scientist proposes a hypothesis about how a newly discovered virus affects humans. Other virus researchers would likely
reject the hypothesis
change the hypothesis to fit their own findings
design new experiments to test the proposed hypothesis
assume that the hypothesis is true for all viruses
Why is creativity considered a scientific attitude?
Scientists need creativity to make good posters to explain their ideas
Creativity helps scientists come up with different experiments
Creative scientists imagine the results of experiments without doing them
Scientists who are creative are better at handling and training animals
Who reviews articles for peer-reviewed journals?
friend of the scientists who wrote the articles
anonymous and independent experts
the scientists who did the experiments
people who paid for the experiments
How does sharing ideas through peer-reviewed articles do not need to be repeated
Peer-reviewed articles are published only when the ideas they contain have been accepted by most scientists
Experiments in peer-reviewed articles do not need to be repeated
Scientists reading the articles may come up with new questions to study
Ideas in the articles always support and strengthen dominant theories
Suppose that a scientific idea is well-tested and can be used to make predictions in numerous new situations, but cannot explain one particular event. This idea is a
hypothesis that is incorrect
hypothesis that must be retested
theory that should be discarded
theory that may need revision
How do scientific theories compare to hypotheses
Theories are the same as hypotheses
Theories unify a broad range of observations and hypotheses
Hypotheses combine the ideas of several theories to explain events
Hypotheses are the dominant view among scientists
Which of the following is NOT a way that science influences society?

Science gives society answers to difficult ethical problems
Science advances technology that is useful to society
Science increases society's understanding of how people affect the environment

Yes; the other branches of biology are more important
Yes; the different branches of biology are interrelated
No; the other branches of biology do not affect evolution
No; each branch of biology is separate from the others
Biologists who work in the fields of genomics and molecular biology study
the biosphere
diseases
DNA
trees
Scientists often try to repeat each other's results. Which of the following should a scientists do to make it easier for others to replicate his or her experiment?
Not use a control to save time
Collect only one set of data
Skip peer-review so the results are available sooner
Use the metric system when communicating procedures and results
