Ans: c) Biological literacy is the ability to integrate ideas about biology
into making wise decisions for oneself.
________ is the study of living things.
Ans: Biology
Thinking scientifically relies on:

Ans: d) objective observation and experimentation
In the laboratory, you see a fuzzy growth on some of the gels in your
incubator. What is the name given to this step of the scientific
method?
Ans: d) observation
If your hypothesis is "Hair that is shaved grows back coarser and
darker," what is your null hypothesis?
Ans: d) There is no difference in the coarseness or color of hair that is
shaved relative to hair that is not shaved.
Which statement is the most reasonable testable prediction for the

The purpose of the experimentation phase of the scientific method is
to:
Ans: d) gather evidence to support or reject a hypothesis.
If you conduct an experiment that rejects your hypothesis, then:
Ans: c) the null hypothesis was a better fit to your data.
A relationship that has been established based on a large amount of
observational and experimental data is a(n):
Ans: d) theory.
Which of the following qualifies as a randomized, double-blind,
controlled experimental study?

Ans: c) A total of 50 men and women of various ages are each given a
candy bar with real sugar, 50 men and women of various ages are each
given a candy bar with artificial sweetener, and 50 men and women of
various ages are not given a candy bar. The people are then observed for
signs of sleepiness. No one (the scientist, the observer, and the subjects)
knows what type of candy bar was eaten, if any.
What type of evidence most increases our confidence in
experimental results?
Ans: c) Three different scientists do three different studies, all with the
same result.
During an experiment to determine if people with more symmetrical
body features have a lower incidence of disease, a researcher first
measures the length of several bones in the subject's hands and
arms. The device used to measure length does not display a readout
of the measurement taken. Instead, a wire connects the measuring
device to a computer that records the data. The computer monitor
