Interpreting Data
These two snakes look remarkably similar to each other. The
coral snake (right) is very poisonous to vertebrates. Hypotheses:
H1: The coral snake’s bright color pattern serves to warn off
potential predators.
H2: The king snake suffers less predation because it mimics or
looks like the coral snake.
H3: The protection that king snakes receive by mimicking coral
snakes will depend on the presence of coral snakes.

Interpreting Data
A team of scientists designed an
investigation that used artificial
snakes to test the previous
hypotheses. Which of the previous
hypotheses are supported by the
results displayed at the right?
a. H1: The coral snake’s bright
color pattern serves to warn off
potential predators.
b. H2: The king snake suffers less
predation because it mimics or
looks like the coral snake.
c. H3: The protection that king
snakes receive by mimicking
coral snakes will depend on the
presence of coral snakes.
d. both a and b

Interpreting Data
Biologists placed artificial snake
mimics in two different localities
to test the hypothesis that
looking like a poisonous snake
only works where the poisonous
snake is found:
1. Outside of the coral snake
range—only king snakes are
present.
2. Inside of the coral snake
range—both coral and king
snakes are present.

Interpreting Data
The data graphed at the right
___________ the hypothesis that
the effectiveness of mimic
coloration depends on the
presence of the poisonous model.
a. supports
b. does not support
c. is irrelevant to

Interpreting Data
Based on this data, which of the
following is a logical hypothesis or
prediction?
a. King snakes outside of the
range of coral snakes will more
closely resemble coral snakes
than populations of king snakes
living within the range of coral
snakes.
b. King snakes outside of the
range of coral snakes will not
resemble coral snakes as
closely as populations of king
snakes that live within the range
coral snakes.
c. Neither prediction is valid.

skeptical of science. Do you think that an informed citizen needs a
firm understanding of science to effectively participate in a
representative society?

Biology and Society
For some, religion and science seem to be
at odds. Others feel that religion and
science are two powerful but separate
ways of human understanding. Most
important, these people do not feel that
science and religion are in conflict.
Do you think that an individual can hold
devout religious beliefs, while at the
same time supporting scientific
understanding?
