Chapter 1: The Science of Biology
CHECK ALL THE APPLY. Choose all options that best completes the statement or
answers the question.
1) Cell theory is one of the foundations of biology. What are the tenets of the cell theory?
Check all that apply.
A) All organisms are made up of more than one cell.
B) All cells have the ability to move.
C) Cells carry genetic material passed to daughter cells during cellular division.
D) Cells arise from other cells through the process of cell division.
E) Organisms are formed through spontaneous generation
F) All living organisms consist of cells
2) Darwin's theory of evolution is supported by many modern pieces of evidence. Check all
that apply.
A) New measurements of the age of the earth.
B) An Understanding of the mechanism of heredity.
C) Human population growth.
D) Comparative Studies of animal structures.
E) Similarities In DNA of related species.
MULTIPLE CHOICE - Choose the one alternative that best completes the statement or
answers the question.
3) Science is subdivided into specific areas of study termed disciplines. These divisions are
artificial but are helpful to narrow the massive scope of scientific knowledge to a manageable
amount. Given what you know about each, which scientific division is likely to present the best
answer to a question about how fluid dynamics affect blood pressure in mammals?
A) Biochemistry –study of chemical reactions needed for life function, usually at the
cellular level.
B) Bioinformatics – use of technology to study and store biological data

selection was a mechanism for:
A) artificial selection.
B) evolution.
C) sexual selection.
D) speciation.
E) overpopulation of finches on the Galapagos Islands.

B) a way to organize how we think about a problem.
C) a concept that is supported by experimental evidence that explains the facts in an area of
study.

A) DNA
B) cell walls
C) organs
D) ability to conduct photosynthesis
11) A yellow jacket, an insect in the order Hymenoptera, stung me. A wasp, an insect in
Hymenoptera, stung me. A hornet, an insect in Hymenoptera, stung me. I see a pattern. All
insects in this order must have stingers. What type of reasoning does this represent?
A) inductive reasoning
B) deductive reasoning
C) reductionism
D) comparative reasoning

13) A suggested explanation that might be true and is subject to testing by further
observations is a(n):
A) experiment.
B) generality.
C) hypothesis.
D) scientific principle.
E) theory.
14) Based on the literature, you hypothesize that students in traditional biology lectures will
have the same grades as students in online biology lectures. You decide to test your hypothesis
by comparing grades of students in traditional and online biology lectures over a semester. As a
result of the experiment, you observe that the grades in the traditional lectures and the grades in
the online lectures are not significantly different. What do these observations allow you to do?
A) reject the hypothesis
B) modify the hypothesis to fit the results
C) develop a scientific theory
D) retain the hypothesis
15) Your microwave will not turn on, and you speculate that a circuit breaker in the house
has been tripped. In scientific terminology, the steps would be described as:
A) forming conclusions from the results of experiments.
B) developing an observation based on a hypothesis.
C) developing a hypothesis based on an observation.
D) testing a prediction generated from a hypothesis.
16) A student poses the question: How does the presence of dissolved salt affect the freezing
point of water? To answer this question, the student set up two conditions. In the first condition,
the student added salt to water in a container and referred to this condition as the variable. In the
second condition, the student did not add any salt to water in a second container and referred to
this condition as the control. The student took both containers and attempted to freeze the water
at various temperatures to assess the freezing point. Would this be a valid experiment?
A) Yes, because there is more than one variable.
B) Yes, because there is one variable and a control
C) No, because there is not more than one variable
D) No because there is only one variable and a control
