Biology - Chapter 1 Review

Which of the following is NOT a goal of science?

• to investigate and understand the natural world

• to explain events in the natural world

• to use data to support a particular point of view

• to use derived explanations to make useful predictions

The work of scientists usually begins with

• testing a hypothesis

• careful observations

• creating experiments

• drawing conclusions

Information gathered from observing a plant grow 3 cm over a two-week period results in

• inferences

• variables

• hypotheses

• data

You suggest that the presence of water could accelerate the growth of bread mold. This is a(n)

• conclusion

• hypothesis

• experiment

• analysis

A hypothesis

• can be completely proven

• may be disproved by a single experiment

• does not have to be tested to be accepted as probably correct

• is a proven fact

Hypotheses may arise from

• prior knowledge

• logical inferences

• informed, creative imagination

• all of the above

In science, a hypothesis is useful only if

• it is proven correct

• it can be proven incorrect

• it can be tested

• the explanation is already known

Which of the following is NOT a part of how scientists work?

• experimenting

• observing

• guessing

• hypothesizing

A controlled experiment allows the scientist to isolate and test

• a conclusion

• a mass of information

• several variables

• a single variable

Scientists publish the details of important experiments so that

• their work can be repeated

• their experimental procedures can be reviewed

• others can try to reproduce the results

• all of the above
