6. Pablo and Johanna have to do a yearlong study for how much the dogs grow
their biology course. After some discussion, they de-
cide to try comparing their dogs and the diet that
they feed them. Each has a dog from the pound, and
both dogs are less than one year old. Pablo feeds
his shepherd-mix dog a special diet of wet and dry
foods from the local vet, while Johanna uses generic
dry kibble from the supermarket for her bulldog. They
want to see which diet results in bigger, healthier,
faster-growing dogs.
According to the information given, one dependent

variable in this study will be ________.
a. how much the dogs grow
b. the type of food the dogs receive
c. the age of the dogs
d. the breed of the dogs
e. the sex of the dogs
7. Scientists use a general process known as the ? to ask scientific method
and answer questions about natural phenomena.
8. s a testable statement that proposes an explanation hypothesis
for a set of observations. It leads to predictions that
can be tested by an experiment.
9. A ? describes specific results that can be expected if a prediction
hypothesis is true.
10. A ? is broader in scope than a hypothesis, is supported theory
by a large body of evidence, and generates many new
hypotheses.
11. A scientific experiment often involves both a treat- Control
ment and a ?, which are alike except for the variable
that the experiment is designed to test.target 5 of 8
12. A ? is a factor that is either manipulated or measured variable
in an experiment.
13. A ? is a quantitative relationship between variables. correlation
14. A review process is in place to make sure that no ? has bias
skewed the results of an experiment.
