GCU BIO 181 CERTIFICATION EVALUATION
FULL QUESTIONS AND SOLUTIONS
VERIFIED PREPARATION MATERIAL
●● independent variable
Answer: The experimental factor that is manipulated; the variable whose
effect is being studied.
●● dependent variable
Answer: the variable that changes in response to manipulations of the
independent variable.
●● control group
Answer: the group that is not exposed to the treatment
●● experimental group
Answer: the group that is exposed to the treatment, that is, to one version
of the independent variable.
●● why formulate a hypothesis
Answer:
, ●● five steps of scientific method
Answer: 1) observation
2) question
3) hypothesis
4) experiment and observe
5)conclude
●● hypothesis vs theory
Answer: A hypothesis is a reasoned prediction of a possible causal
correlation among multiple phenomena.
a theory is a tested, well-substantiated, unifying explanation for a set of
verified, proven factors.
●● hypothesis based science
Answer: Explains the nature by proposing hypothesis and predicts the
specific results by applying general principles and using Controlled
variables in an experiment.
●● observation-based science
Answer: still experimenting but conclusions are derived from the
observations made in the lab, there isn't any "numerical" data
●● cell in hYPOtonic solution
