CH 1 TEST REVIEWMouse Mischief
Being skeptical and being open to change are parts of
homeostasis
control groups
scientific thought
In science, ___________________are truths that are valid everywhere in the universe
universal law
hypotheses
predictions
The system of moral principles and values needed for scientific investigations is called __________________
theories
ethics
observations
Which is a reason to study science?
to help take better care of your health
to be a wise consume
Both (a) and (b)
A wide range of observations is explained by
theory
question
controlled experiment
During an experiment, the group that does not change is the
organism.
control.
heredity.
A specific, testable prediction for a limited set of conditions is a
theory
universal law.
hypothesis.
Each of the following steps is involved in scientific thought except
questioning ideas.
making observations.
evaluating evidence.
preserving bias.
In which aspects of science are ethics involved?
running experiments with humans and other animal
reporting results of controlled experiments
publishing scientific studies
All of the above
All objects in the universe are subject to
scientific skepticism
the law of gravity
the law of indirect observation.
the International System of Units.
In which three areas can studying science aid a nonscientist?
health, consumer issues, and solving community problem
health, consumer issues, and following universal laws
consumer issues, following universal laws, and reinstating conventional wisdom
health, critical thinking, and reinstating conventional wisdom
What is a control group?
a group of people in a scientific study
a group of scientists in charge of conducting an experiment
a group that serves as a standard of comparison in an experiment
a group that receives only an experimental treatment
In a controlled experiment, what do scientists measure?
how many dependent variables they have
how many independent variables they have
how the dependent variables change in response to changes in the independent variable
how the independent variables change in response to changes in the dependent variable
What is the main reason for running a controlled experiment?
to make observations
to test a hypothesis
to formulate new questions
to get information for a study
Which of these could be useful in a microbiology lab?
electron microscopy
sterile technique
Both (a) and (b)
Neither (a) nor (b)
Which of the following is true about theories and hypotheses?
A hypothesis is highly tested, but a theory is not testable.
A hypothesis is a general explanation, but a theory is a specific prediction.
One hypothesis can lead to many theories
Several related hypotheses can be incorporated into a theory

zoology and genetics
genetics and evolutionary theory
Which list includes four of the seven properties of living things?
cellular organization, biochemical organization, reproduction, and evolution
reproduction, heredity, evolution, and growth
heredity, growth, homeostasis, and responsiveness
homeostasis, metabolism, reproduction, and evolution
In which situation are scientists most likely to collect data remotely
when their computers are down
when they are studying organisms in the fossil record
when they are on vacation
when they are studying organisms that migrate
A scientist is investigating a new treatment for a disease that affects thousands of people. Many people with this disease volunteer to be part of the study. Which of
the following is an ethical concern that the scientist must address before conducting the study?The scientist must ensure that the
treatment will be effective.The scientist must ensure that the
study’s results will not be shared with
other scientistsThe scientist must inform the volunteers about the potential dangers of participating in the study.The scientist must demonstrate
the treatment on him or herself.
Which of the following is an example of scientific skepticism?
A scientist investigates how a universal law
affects many fields of studyA scientist falsely claims to have discovered a cure for diabetes.
A scientist conducts an experiment that supports the conclusions of another scientist.
A scientist questions another scientist’s conclusions and develops an experiment to test an alternative hypothesis.
