Annie wants to study the effect of glucose on bacterial colonies. She grows two colonies of bacteria—one with glucose present in the environment and one in an environment without glucose. Categorize the statements about the experiment as either hypotheses or observations.

Glucose may cause
an increase in
bacterial growth.
The bacterial colonies grown
without glucose don’t have
capsules around their cells.
Bacterial growth in the
glucose environment
increased rapidly and
then stopped after
some time.
Increased glucose may
lead to capsule
formation in bacteria.
