ATI TEAS PRACTICE TEST Science
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. 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. - ANSWER 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. - ANSWER 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.
,ATI TEAS PRACTICE TEST Science
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. The epiglottis covers the trachea during swelling, thus
preventing food from entering the airway.
- 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. - ANSWER 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.
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. Cell layers and cell shape are the criteria
for classifying epithelial tissue.
,ATI TEAS PRACTICE TEST Science
- 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. - ANSWER 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.
How many organ system are in the human body?
A. 12
B. 15
C. 9
D. 11 - ANSWER D. There are 11 organ systems n the human body.
- Circulatory System
- Digestive System
- Endocrine System
- Integumentary System
- Lymphatic System
- Muscular System
- Nervous System
- Reproductive System
- Respiratory System
- Skeletal System
- Urinary System
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. Cilia.
- The cilia are the tiny hairs in the respiratory system that are responsible for removing
reign matter from the lungs.
, ATI TEAS PRACTICE TEST Science
- 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.
Organized from highest to lowest, what is the hierarchy of the human body's structures
is as follows:
- Organism, organ systems, organs, tissues.
Which of the following comes next?
A. Organs, cells, tissues, molecules, atoms
B. Organ system, organism, organ, cells, tissues, atoms, molecules
C. Organism, organ system, organs, tissues, cells, molecules, atoms
D. Organism, organ, cells, tissues, molecules, atoms - ANSWER C. The order of
hierarchy of human body structures is as follows:
- Organism
- Organ systems
- Organs
- Tissues
- Cells
- Molecules
- Atoms
Muscles are types of tissues, so muscles do not have a separate place in the hierarchy
but instead fall within the types of tissues.
THE NEXT TWO QUESTIONS ARE BASED ON THE PERIODIC TABLE
On average, how many neutrons does one atom of bromine(Br) have?
Atomic # - 35
Atomic mass - 79.9
A. 35
B. 44.90
C. 45
D. 79.90 - ANSWER B. 44.90
79.9-35 = 44.90
On average, how many protons does one atom of zinc (Zn) have?
Atomic # - 30
Atomic mass - 65.39
A. 30
B. 35
C. 35.99
D. 65.39 - ANSWER A. 30
The number of protons is the same for every atom of a given element and is the
elements's atomic number; in this case 30 for Zinc (Zn).
Which statement below correctly describes the movement of molecules in the body
and/or in relation to the external environment?
