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.

A. The following statements are hypotheses:
1. Glucose may cause an increase in bacterial growth.
2. Increased glucose may lead to capsule formation in bacteria.

B. The following statements are observations:
1. The bacterial colony grown without glucose do not have capsules around their cells.
2. Bacteria growth in the glucose environment increase rapidly and then stopped after sometime.

What are the four ranges of bacterial growth?

It has been determined that in a closed machine or batch lifestyle (no food added, no wastes eliminated) microorganisms will grow in a predictable pattern, ensuing in an increasing curve composed of four brilliant levels of increase: the lag section, the exponential or log segment, the desk-bound section, and the lack of existence or decline phase.
