Question
Chapter 1, Problem 6CHI
Summary Introduction
The tiny organisms which could be viewed only under the aided eye are referred to as microorganisms. These microbes can be visible only under the microscopes. The microorganisms are diverse in nature and it represents all the great kingdoms of life. In order to understand the different types of microbes, they are classified or grouped in various ways. The microbes are used as experimental models for the scientific researches.

LESSON 1.1 Review
Q KEY IDEAS
1. In your own words, define the term science.
2. Why are hypotheses so important to controlled
experiments?
3. How does a theory differ from a hypothesis?
CRITICAL THINKING
4. Form a Hypothesis You observe mold growing
on one side of a slice of bread, but not on the
other side. Form a hypothesis to explain this dif-
ference in mold growth.
14 Chapter 1 The Science of Biology
5. Plan an Investigation Design a controlled exper-
iment to test the effect of water temperature
on goldfish. Be sure to include your hypothesis,
independent variable, and dependent variable,
as well as the experimental and control groups in
your experiment.
Think about minimal inhibitory concentration (MIC) assays. A set of tubes, all containing the same amount of bacterial cells, have decreasing amount of antibiotic X added to them. Tube 1 had 0mg/ml, Tube 2 has 100mg/ml, tube 3 has 50mg/ml, 4=25, 5=12.5, 6=6.25, and tube 7 has 3.125. If bacteria grew in tubes 1, 4, 5, 6, 7, what is the MIC of this antibiotic for this bacteria?
Select one:
a.None of the Above
b.3.125 mg/ml
c.25 mg/ml
d.0 mg/ml
e.50 mg/ml
