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.
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."
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.
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.
3. 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).
4. 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.
5. 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.
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.
6. 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.
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.
7. How many organ system are in the human body?
A. 12
B. 15
C. 9
D. 11
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
8. 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
B. Cilia.
- The cilia are the tiny hairs in the respiratory system that are
responsible for removing reign 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.
9. 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
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.

have?
Atomic # - 35
Atomic mass - 79.9
A. 35
B. 44.90
