2) When setting up an experiment, what are the independent variable, dependent
variable, and control of the experiment?

7) How do you determine if something is a living thing or a nonliving thing?
8) What is metabolism (metabolic activity)?
9) What is homeostasis? Explain how the human body maintains homeostasis (one
example).
10) What is asexual reproduction? What kind of offspring does it produce
(compared to the parent)?
11) What is sexual reproduction? What kind of offspring does it produce (compared
to the parents)?
12) What is the cell theory?
13) What is similar to a cell but is not considered a living thing because it can’t
reproduce without a host?

25) How are enzymes named? Give an example.
26) Draw a graph that shows how temperature and an enzyme’s rate of reaction are
related?
27) Which pH is neutral? Which pH is considered an acid? Which pH is considered a
base?
