Question 1
The first four steps on the scientific method are as follows:
I. Identify the problem.
II. Ask questions.
III. Develop a hypothesis.
IV. Collect data and experiment on that data.
Which of the following is the fifth step in the scientific method?
A. Observe the data
B. Analyze the results
C. Measure the data
D. Develop a conclusion
Answer: B
Rationale: There are six steps in the scientific process. The results of step four must be
analyzed before reaching the final step, "Develop a conclusion."
Question 2
Which of the following is FALSE regarding the use of qualitative and quantitative data
in scientific research?
A. Quantitative data is collected through numerical measurements
B. Quantitative data is more accurate than qualitative data
C. Qualitative data is focused on perspectives and behavior
D. Qualitative data is collected through observation and interviews
Answer: B
Rationale: The two types of measurement important in science are quantitative
(numerical results) and qualitative (descriptions or qualities). Neither is inherently
more accurate; they serve different purposes.

,Question 3
The chart below shows the average snowfall in inches for a town in Michigan's Upper
Peninsula during the months November through April.
Month Snowfall (inches) Sunny Days
November 15 8
December 35 5
January 40 4
February 38 5
March 25 7
April 10 12
Which of the following can be concluded based on the information that is provided in
the chart?
A. April is not a good month to go skiing in the Upper Peninsula
B. Snowfall blocks the sunshine and reduces the number of sunny days
C. The fewest sunny days occur in the months with the heaviest snowfall
D. There is no connection between the amount of snowfall and the number of sunny
days
Answer: C
Rationale: The chart shows two specific changes: snowfall levels from November to
April and sunny days from November to April. The fewest sunny days occur in the
months with the heaviest snowfall.
Question 4
Which of the following statements correctly describes the function of the corresponding
physiologic structure?
A. The trachea connects the throat and the stomach, encouraging food to follow this
path through contractions
B. The esophagus is the cylindrical portion of the respiratory tract that joins the larynx
with the lungs
C. The diaphragm is a muscle that controls the height of the thoracic cavity, decreasing
the height on contraction, and increasing the height on relaxation causing expiration
D. The epiglottis covers the trachea during swallowing, preventing food from entering
the airway
Answer: D
pg. 2
,Rationale: The trachea (windpipe) is the cylindrical portion of the respiratory tract
that joins the larynx with the lungs. The esophagus connects the throat and the stomach.
The diaphragm increases thoracic cavity height on contraction (inspiration) and
decreases it on relaxation (expiration). The epiglottis covers the trachea during
swallowing.
Question 5
Which of the following is an example of the location and function of cartilage in the
body?
A. The dense connective tissue that comprises the better part of the structural skeleton
B. The supportive pads that provide cushion at joints, such as between the vertebrae of
the spinal cord
C. The connective structure made of fibrous collagen that connects muscles and bones
D. The layer beneath the skin and on the outside of internal organs that provides
cushioning and protection
Answer: B
Rationale: Cartilage, a strong form of connective tissue, cushions and supports joints.
Cartilage also makes up the larynx and the outer ear. Bone comprises the skeleton.
Tendons connect muscles to bones. Fat forms the layer beneath the skin.
Question 6
Two criteria for classifying epithelial tissue are:
A. Cell type and cell function
B. Cell shape and cell type
C. Cell layers and cell shape
D. Cell function and cell layers
Answer: C
Rationale: Cell layers refer to the amount of cells that separate the basement
membrane from the surface (simple, stratified, or pseudostratified). Cell shapes refer to
the shape of the outer cells (squamous, columnar, or cuboidal).
Question 7
The parathyroid gland is located:
A. On the lateral lobes of the thyroid gland, on the posterior aspect
B. On the pyramidal lobe of the thyroid gland, on the posterior aspect
pg. 3
, C. On the lateral thyroid gland, on the anterior aspect
D. On the left lateral lobe of the thyroid gland, on the anterior aspect
Answer: A
Rationale: The parathyroid gland is part of the endocrine system. When calcium in
blood diminishes to unhealthy levels, the parathyroid gland secretes a hormone that
encourages bones to release calcium into the bloodstream. It also regulates phosphate in
the blood by stimulating excretion of phosphates in the urine.
Question 8
How many organ systems are in the human body?
A. 12
B. 15
C. 9
D. 11
Answer: D
Rationale: There are 11 organ systems in the human body: Circulatory, Digestive,
Endocrine, Integumentary, Lymphatic, Muscular, Nervous, Reproductive, Respiratory,
Skeletal, and Urinary.
Question 9
Which element or structure within the respiratory system is responsible for removing
foreign matter from the lungs?
A. Bronchial tubes
B. Cilia
C. Trachea
D. Alveoli
Answer: B
Rationale: The cilia are the tiny hairs in the respiratory system responsible for
removing foreign matter from the lungs. The cilia are located within the bronchial tubes,
but it is the cilia that have the responsibility for removing inappropriate materials before
they enter the lungs.
Question 10
Organized from highest to lowest, what is the hierarchy of the human body's structures?
A. Organs, cells, tissues, molecules, atoms
pg. 4
