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.
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.
,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.
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.
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
C. Cell layers and cell shape are the criteria for classifying epithelial tissue.
