Chapter 1 Bio

Science differs from other disciplines, such as history, and the arts, because science relies on...

• facts
• theories
• testing explanations
• observations

Measurements made while observing plant growth 3cm 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 viruse researchers would likely

• reject the hypothesis
• change the hypothesis to fit their own findings
• design new experiments to test the propose hypothesis
• assume that the hypothesis is true for all viru

Why is creativity considered a scientific method?

• 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?

• Friends 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 help advance science?

• peer-reviewed articles are published only when the ideas they contain have been accepted by mot 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 stregnthen 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 

• 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 provides answers to some of society's practical problems
• Science gives society answers to difficult eithical issues
• Science advances technology that is useful to society
• Science increases society's understanding of how people affect the environment
