4) When a lepidopterist examined museum specimens of a particular moth species, she noticed
that the variation in color was distributed as shown in the first graph. She was surprised because
her data indicated the distribution of colors shown in the second graph. Which of the following

1.3 Scenario Questions
After reading the paragraph below, answer the questions that follow.
Researchers set up a study to determine whether large doses of a nutritional supplement would
shorten the length of time it takes to recover from a cold. Three thousand volunteers were split
into two groups. For two weeks, members of group A took 3,000 mg of the supplement daily.
Group B received 3,000 mg of a placebo. At the end of the two-week period, the researchers
inserted live cold viruses directly into the noses of all the volunteers. The volunteers in both
group A and group B continued to take their daily pills. All the volunteers got colds, and there
was no significant difference in the length of time the colds lasted.
1) Which was the experimental group?
A) group A only
B) group B only
C) all 3,000 volunteers
D) the researchers that inserted the cold virus
Answer: A
Topic: 1.9
Skill: Application/Analysis
Learning Outcome: 1.6
Global LO: 1, 2
2) To have confidence that the results of the experiment were valid, you’d also want to know
A) whether any volunteers had colds at the start of the experiment.
B) whether the volunteers exercised daily.
C) whether the volunteers all worked for the same company.
D) what the volunteers ate during the experiment.
Answer: A
Topic: 1.9
Skill: Application/Analysis
Learning Outcome: 1.6

After reading the paragraph below, answer the questions that follow.
Researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells
contracting in unison. The robot, made of a polymer similar to that used in making contact
lenses, is bathed in heart cells with supporting fibroblasts, which then attach to the robot and
provide movement as they contract.
3) If the creators of the robot wanted to provide evidence that it is alive, which of the following
properties would be best to use as evidence?
A) The robot can move.
B) The robot must be bathed in a liquid medium to provide nutrition for its cells.
C) New robots can be reproduced by researchers using the same manufacturing process.
D) The robot has two different types of cells, fibroblasts and cardiac cells.
Answer: B
Topic: 1.1, 1.11
Skill: Synthesis/Evaluation
Learning Outcome: 1.2
Global LO: 2
4) All of the cardiac cells working together can cause the robot leg to move in a way that
individual cells could not. This is an example of
A) adaptation.
B) emergent properties of cells.
C) energy flow through an ecosystem.
D) internal environment regulation.
Answer: B
Topic: 1.2, 1.11
Skill: Application/Analysis
Learning Outcome: 1.1
Global LO: 2
5) The robot’s cardiac cells, working together in synchrony, could be considered at what level in
life’s hierarchy of organization?
A) organism
B) organelle
C) tissue
D) organ system
Answer: C
Topic: 1.2, 1.11
Skill: Application/Analysis
Learning Outcome: 1.3

After reading the paragraph below, answer the questions that follow.
Scientists interested in knowing the best way to restore an area after a temporary road was built
through it completed a study comparing two treatments: (1) restoring the contour of an area so
that there was no longer a depression or cut-through where the road was previously and (2)
simply abandoning the area to allow vegetation to return on its own. They wanted to know
whether either or both of these treatments would return the aboveground vegetation and the
belowground soil properties to their original state, as seen in a similar area where there had never
been a road.
6) This study was focused on which level of life’s hierarchy?
A) organism
B) community
C) population
D) ecosystem
Answer: D
Topic: 1.2
Skill: Application/Analysis
Learning Outcome: 1.3
Global LO: 2, 5
7) Which of the following best describes the data that the scientists should collect and how they
should be compared?
A) comparison of plant species in the recontoured area, the abandoned area, and the never-
roaded area
B) comparison of properties of soil and plant species in the contoured area and abandoned area
C) comparison of soil properties and species of plants present in the contoured area with the
never-roaded area and of the abandoned area with the never-roaded area.
D) comparison of soil properties only among all three areas since soil properties will determine
plant species
Answer: C
Topic: 1.9
Skill: Synthesis/Evaluation
Learning Outcome: 1.6
Global LO: 1, 2
8) In this experiment, the area that had never had a road is useful to the experiment because
A) at least three samples are necessary to have a valid experiment.
B) the area never roaded serves as a control for the experimental variables of recontoured and
abandoned.
C) the researchers need to know what species of plants were common to all three areas.
D) since all three areas had existed for the same amount of time, the third area allowed time to be
controlled as a variable.
Answer: B
Topic: 1.9
Skill: Synthesis/Evaluation
Learning Outcome: 1.6
Global LO: 1, 2
9) The researchers concluded, “These findings support the prediction that recontouring
accelerates the rehabilitation of key ecohydrologica properties toward reference dynamics.”
What does this mean?
A) Recontouring makes the vegetation in the area grow out of control.
B) Recontouring allows the water properties of the system to return to normal faster.
C) Abandonment is the better treatment for restoration.
D) Their original prediction that recontouring would produce greater plant diversity was
supported.
Answer: B
Topic: 1.8
Skill: Application/Analysis
Learning Outcome: 1.6
