ATI TEAS PRACTICE TEST ScienceQuestions and answers | With complete
solution 2024/25 RATED A+ ii ii ii ii ii ii ii ii ii ii
The first four steps on the scientific method are as follows:
ii ii ii
I. Identify the problem.
ii ii
II. Ask questions. ii ii ii
III. Develop a hypothesis.
ii ii ii ii ii ii ii
Iv. Collect data and experiment on that data.
ii ii ii ii ii ii ii ii ii ii ii
Which of the following is the fifth step in the scientific method?
ii ii ii
A. Observe the data.
ii ii ii
B. Analyze the results.
ii ii ii
C. Measure the data.
ii ii ii
D. Develop a conclusion.
ii ii ii ii
B. Analyze the results.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- There are six steps in the scientific process. The results of step four must be analyzed
ii ii ii ii ii ii ii ii
before reaching the final step. "Develop a conclusion."
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
Which of the following is FALSE regarding the use of qualitative and quantitative data in
ii ii
scientific research?
ii ii ii ii ii ii ii
A. Quantitative data is collected through numerical measurements.
ii ii ii ii ii ii ii ii
B. Quantitative data is more accurate than qualitative data.
ii ii ii ii ii ii ii ii
C. Qualitative data is focused on perspectives and behavior.
ii ii ii ii ii ii ii ii
D. Qualitative data is collected through observation and interviews.
ii ii ii ii ii ii ii ii
B. Quantitative data is more accurate than qualitative data.
ii ii ii ii ii ii ii ii ii ii ii ii
The two types of measurement important in science are qualitative (When a numerical
ii ii ii ii ii ii ii ii ii ii ii ii
result is used) and qualitative (when descriptions or qualities are reported).
ii ii ii ii ii ii ii ii ii ii ii ii
- Qualitative data is collected through observation and interviews, and focuses on the
ii ii ii ii
informant's behavior and perspectives.
ii ii ii ii ii ii ii
THE NEXT QUESTION REFERS TO THE FOLLOWING GRAPHICS:
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
The chart above shows the average snowfall in inches for a two on Michigan's Upper
ii ii ii ii ii ii ii ii ii ii ii ii ii
Peninsula, during the months November through April. Which of the following can be
ii ii ii ii ii ii ii ii ii ii ii
concluded based on the information that is provided in the chart?
ii ii ii ii ii ii ii ii ii ii ii ii ii

ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
D. There is no connection between the amount of snowfall and the number of sunny days.
ii
C. ii ii ii ii ii ii ii ii ii ii ii ii ii
The chart shows two specific changes: snowfall levels from November to April and sunny
ii ii ii ii ii
days from November to April.

Which of the following statements correctly describes the function of the corresponding
ii ii
physiologic structure?
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The trachea connects the throat and the stomach, encouraging food to follow this path
ii ii
through contractions.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
B. The esophagus is the cylindrical portion of the respiratory tract that joins the larynx with
ii ii
the lungs.ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
C. the diaphragm is a muscle that controls the height of the thoracic cavity, decreasing the
ii ii ii ii ii ii ii ii ii ii ii
height on contraction, and increasing the height on relaxation causing expiration.
ii ii ii ii ii ii ii ii ii ii ii ii
D. The epiglottis covers the trachea during swallowing, preventing food from entering the
ii
airway. ii ii ii ii ii ii ii ii ii ii ii ii ii
D. The epiglottis covers the trachea during swelling, thus preventing food from entering the
ii ii
airway.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The trachea (windpipe) is cylindrical portion of the reparatory tract that joins the larynx
ii ii ii ii
with the lungs.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- The esophagus connects the throat and the stomach. When a person swallows, the
ii ii ii ii ii ii ii ii ii ii ii ii ii
esophagus contracts to force the food down into the stomach. The esophagus secretes
ii ii ii ii
mucus for lubrication.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The diaphragm is a muscle that controls the height of the thoracic cavity, increasing the
ii ii ii ii ii ii ii ii ii ii ii
height on contraction (inspiration), and decreasing the height on relaxation (expiration).
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
Which of the following is an example of the location and function of cartilage int he body?
ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The dense connective tissue that comprises the better part of the structural skeleton.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
B. The supportive pads that provide cushion at joints, such as between the vertebrae of the
ii ii
spinal cord.
ii ii ii ii ii ii ii ii ii ii ii ii
C. The connective structure made of fibrous collagen that connects muscles and bones,
ii ii ii ii ii ii ii ii ii ii
such as the connection of the patella to the quadricep.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
D. The layer beneath the skin and on the outside of internal organs that provides
ii ii ii
cushioning and protection.
ii ii ii ii ii ii ii ii ii ii ii ii
B. The pads that support the vertebrae are made up of cartilage.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cartilage, a strong form of connective tissue, cushions ad supports the joints. Cartilage
ii ii ii ii ii ii ii ii ii
also makes up the larynx and the outer ear.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Bone is a form of connective tissue that comprises the better part of the skeleton. It
ii ii ii ii ii ii ii
includes both organic and inorganic substances.
ii ii ii ii ii ii ii ii ii ii ii ii ii
- Tendons connect the muscles to other structures of the body, typically bones. Tendons
ii ii ii ii ii ii ii ii ii ii ii
can increase and decrease in length as the bones move.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Fat is a combination of lipids; in humans, fat forms a layer beneath the skin and on the
ii ii ii ii ii
outside of the internal organs.
ii ii ii ii ii ii
Two criteria for classifying epithelial tissue are:
ii ii ii ii ii
A. Cell type and cell function
ii ii ii ii ii
B. Cell shape and cell type
, ii ii ii ii ii
C. Cell layers and cell shape
ii ii ii ii ii
D. Cell function and cell layers
ii ii ii ii ii ii ii ii ii ii ii ii
C. Cell layers and cell shape are the criteria for classifying epithelial tissue.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cell layers refers to the amount of cells that separate the basement membrane from the
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
surface, such as a simple single layer, a stratified layer (2 or more), or a pseudostratfied
ii ii
layer.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- Cell shapes refer to the shape of the outer cells and can be squamous, columnar or
ii
cuboidal. ii ii ii ii ii
Where is the parathyroid gland located?
ii ii ii ii ii ii ii ii ii ii ii ii
A. On the lateral lobes of the thyroid gland, on the posterior aspect.
ii ii ii ii ii ii ii ii ii ii ii ii
B. On the pyramidal lobe of the thyroid gland, on the posterior aspect.
ii ii ii ii ii ii ii ii ii
C. On the lateral thyroid gland, on the anterior aspect.
ii ii ii ii ii ii ii ii ii ii ii ii ii
D. On the left lateral lobe of the thyroid gland, on the anterior aspect.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
A. The parathyroid gland is located on the lateral lobes of the thyroid gland in the neck, on
ii ii ii ii
the posterior aspect.
ii ii ii ii ii ii ii ii
- It is part of the endocrine system.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- When the supply of calcium in blood diminishes to unhealthy levels, the parathyroid gland
ii ii ii ii ii ii ii ii ii ii ii ii ii ii
motivates the secretion of a hormone that encourages the bones to release calcium into
ii ii ii ii ii ii ii ii ii ii ii ii ii
the bloodstream. The parathyroid Gand also regulates the amount of phosphate in the
ii ii ii ii ii ii ii ii ii ii
blood by stimulating the excretion of phosphates in the urine.
ii ii ii ii ii ii ii ii

ii ii ii ii ii
foreign matter from the lungs?
ii ii
A. Bronchial tubes
ii
B. Cilia ii
C. Tracheaii
D. Alveoliii ii
B. Cilia.
ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The cilia are the tiny hairs in the respiratory system that are responsible for removing
ii ii ii ii ii ii
reign matter from the lungs.
, ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii ii
- The cilia are located within the bronchial tubes, but it is the cilia that have the responsibility
ii ii ii ii ii ii ii ii ii
for removing inappropriate materials before they enter the lungs.

Muscles are types of tissues, so muscles do not have a separate place in the hierarchy but
ii ii ii ii ii ii ii
instead fall within the types of tissues.
