Question 1

Single-celled prokaryotes

Accepted Answer

A)   lack a membrane bounded nucleus.
B)   are classified in the domains Bacteria and Archaea.
C)   are found in almost all habitats.
D)   All of the choices are correct.

Question 2

Dr. James considers the bacteria grown at body temperature to be the control group and room temperature the experimental group. Do you agree with this reasoning?

Accepted Answer

One knows what to expect concerning the ...

Question 3

An elementary student decides to conduct an experiment comparing the effectiveness of two commercial soaps as cleaning agents, using each in paired tests of different types of stains and colors of cloth, where the only variable was the soap used. The student will use the judgment of classmates to decide if the stains remain equal or if soap one cleans better than the other in each test run. However, the student makes no prediction of which soap is expected to perform best.

Accepted Answer

A)   This lacks a hypothesis and is therefore not a scientific test.
B)   This lacks any control group (no-soap treatment)  and therefore will provide no meaningful results.
C)   Because this is based on the subjective judgments of students, it is not objective and therefore not scientific.
D)   This is a scientific procedure, although it does lack a stated hypothesis describing an anticipated outcome.
E)   This experimental design has all the components and procedures of the scientific method.

Question 4

Dr. James performed another experiment. Instead of inoculating the test tubes with Staphylococcus, he used the bacterium, Streptococcus. He found that Streptococcus grew better at body temperature than at room temperature. This is a replicate of the first experiment.

Accepted Answer

A)   True
B)   False This is not a replicate of the first experiment. Dr. James used Streptococcus instead of Staphylococcus. B

Question 5

Which of the following domains contains the most primitive prokaryotes that live in extreme environments?

Accepted Answer

A)   Archaea
B)   Bacteria
C)   Plantae
D)   Fungi
E)   Eukarya

Question 6

Choose which of the the following statements is a hypothesis for an experiment.

Accepted Answer

A)   Based on the data collected during an experiment, S. aureus grows better at body temperature than room temperature.
B)   Based on previous experience, it is predicted that S. aureus will grow better at body temperature than at room temperature.
C)   S. aureus grew equally well at room temperature and at body temperature.
D)   Based on the data collected during the experiment, it is confirmed that S. aureus grew better at room temperature.

Question 7

A researcher reports he has conducted many experiments where a galvanometer (lie detector)  was hooked up to detect a plant's responses. He reports that when a spider was released near the plant, the spider's decision to escape was picked up by the plant, "causing a reaction in the leaf." When other researchers repeated the experiment, they could not get any galvanometer responses. The researcher then concluded that plants could be put into a faint by humans.

Accepted Answer

A)   This is a justified conclusion from a research design that appears to follow the scientific method.
B)   The only problem with this general research plan is that it lacks a control.
C)   Results must be somewhat repeatable and these results that only work for this researcher do not qualify as science.
D)   The design is scientific; it just lacks a hypothesis.
E)   If the researcher has actual numerical counts, this must be accepted as valid science. C

Question 8

An earlier classification grouped organisms by whether they inhabited the air, land or sea. However, the five-kingdoms-of-life and three-domains system divided into class-order-family-genus-species as described in this chapter is superior because it

Accepted Answer

A)   better represents the origin of features held in common-the unity of life in DNA, etc.
B)   better reflects the origin of adaptations-the diversity of life for differing environments.
C)   allows the organization of over 900,000 different species.
D)   groups organisms based on similarities related to their structure and evolution.
E)   All of the choices are correct.

Question 9

Living things must obey the laws of chemistry and physics.

Accepted Answer

A) True 
 B)False  True

Question 10

Extinction can occur if a species is unable to adapt to a changing environment.

Accepted Answer

A) True 
 B)False

Question 11

Organisms belonging to the same _____ would be the most closely related.

Accepted Answer

A)   kingdom
B)   phylum
C)   family
D)   class
E)   order

Question 12

The classification system most commonly used by biologists today contains five domains.

Accepted Answer

A) True 
 B)False

Question 13

Both living and nonliving entities are organized at the cellular level.

Accepted Answer

A) True 
 B)False

Question 14

What type of information does science provide for society?

Accepted Answer

A)   information about the natural world
B)   information about the supernatural world
C)   information about religious beliefs
D)   information about religious beliefs and the natural world

Question 15

The expected outcome of an experiment is known as

Accepted Answer

A)   a scientific model.
B)   an experiment.
C)   prediction.
D)   a scientific theory or principle.
E)   experimental results.

Question 16

Which of the following features are present at the ecosystem level?

Accepted Answer

A)   chemical cycling through the food chain
B)   energy flow that begins at the producer level
C)   input of solar energy
D)   complex interactions between a variety of populations
E)   all are features of an ecosystem

Question 17

From Kansas to central Indiana to Pennsylvania, many people believe that they have water moccasins (also called "cottonmouths")  in their ponds. Some assert they have seen them, although they are certainly not so foolish as to try to capture one alive. Meanwhile, the fish and game offices and the range maps in the herpetology books indicate that this poisonous snake does not breed this far north. What is the most scientific attitude to assume on this issue?

Accepted Answer

A)   Observations by both the public and the fish and game officers are subjective so this is not easily resolved objectively.
B)   A simple field trip to the pond locations-that resulted in the capture and confirmation of the identity of the snakes-would settle the matter.
C)   Scientific books with range maps are based on field research and, therefore, determine the truth in this case.
D)   Because living organisms are active, scientific theories in biology always change.

Question 18

A cell is to a tissue as an atom is to a

Accepted Answer

A)   molecule.
B)   subatomic particle.
C)   electron.
D)   population.

Accepted Answer

A)   observation
B)   experimentation
C)   neither observation nor experimentation
D)   both observation and experimentation

Question 20

Living organisms are made up of cells.

Accepted Answer

A) True 
 B)False
