ATI TEAS PRACTICE TEST Science Exam
Questions and Answers
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. - correct answers✅✅B. Analyze the results.
- There are six steps in the scientific process. The results of step four must be
analyzed before reaching the final step. "Develop a conclusion."
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. - correct
answers✅✅B. Quantitative data is more accurate than qualitative data.
The two types of measurement important in science are qualitative (When a
numerical result is used) and qualitative (when descriptions or qualities are
reported).

- Qualitative data is collected through observation and interviews, and
focuses on the informant's behavior and perspectives.
THE NEXT QUESTION REFERS TO THE FOLLOWING GRAPHICS:
The chart above shows the average snowfall in inches for a two on
Michigan's Upper Peninsula, during the months November through April.
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 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. - correct answers✅✅C.
The chart shows two specific changes: snowfall levels from November to
April and sunny days from November to April.
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. - correct answers✅✅D. The epiglottis covers the
trachea during swelling, thus preventing food from entering the airway.

Questions and Answers
- The trachea (windpipe) is cylindrical portion of the reparatory tract that
joins the larynx with the lungs.
- The esophagus connects the throat and the stomach. When a person
swallows, the esophagus contracts to force the food down into the stomach.
The esophagus secretes mucus for lubrication.
- The diaphragm is a muscle that controls the height of the thoracic cavity,
increasing the height on contraction (inspiration), and decreasing the height
on relaxation (expiration).
Which of the following is an example of the location and function of cartilage
int he 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, such as the connection of the patella to the quadricep.
D. The layer beneath the skin and on the outside of internal organs that
provides cushioning and protection. - correct answers✅✅B. The pads that
support the vertebrae are made up of cartilage.
- Cartilage, a strong form of connective tissue, cushions ad supports the
joints. Cartilage also makes up the larynx and the outer ear.
- Bone is a form of connective tissue that comprises the better part of the
skeleton. It includes both organic and inorganic substances.
- Tendons connect the muscles to other structures of the body, typically
bones. Tendons can increase and decrease in length as the bones move.
- Fat is a combination of lipids; in humans, fat forms a layer beneath the skin
and on the outside of the internal organs.

Questions and Answers
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 - correct answers✅✅C. Cell layers and cell
shape are the criteria for classifying epithelial tissue.
- Cell layers refers to the amount of cells that separate the basement
membrane from the surface, such as a simple single layer, a stratified layer
(2 or more), or a pseudostratfied layer.
- Cell shapes refer to the shape of the outer cells and can be squamous,
columnar or cuboidal.
Where is the parathyroid gland 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.
C. On the lateral thyroid gland, on the anterior aspect.
D. On the left lateral lobe of the thyroid gland, on the anterior aspect. -
correct answers✅✅A. The parathyroid gland is located on the lateral lobes
of the thyroid gland in the neck, on the posterior aspect.
- It is part of the endocrine system.
- When the supply of calcium in blood diminishes to unhealthy levels, the
parathyroid gland motivates the secretion of a hormone that encourages the
bones to release calcium into the bloodstream. The parathyroid Gand also
regulates the amount of phosphate in the blood by stimulating the excretion
of phosphates in the urine.
