EXPLAINED RATIONALES
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."
Which structure controls the hormones secreted by the pituitary gland?
A. hypothalamus
B. adrenal gland
C. testes
D. pancreas
A. the hypothalamus controls the hormones sec rated by the pituitary gland.
-The part of the brain maintains the body temperature and hips to control metabolism.
,- the adrenal glands, which lie above the kidneys, secrete steroidal hormones, epinephrine,
and norepinephrine.
- The testes are the male reproductive glands, responsible for the production of sperm and
testosterone
- The pancreas secretes insulin and a fluid that aids indigestion.
Where does gas exchange occur in the human body?
A. alveoli
B. bronchi
C. larynx
D. pharynx
A. Gas exchange occurs in the alveoli, the minute air sacs on the interior of the lungs.
- The bronchi are large cartilage-based tubes of air; they extend from the end of the trachea
into the lung; where they branch apart.
- the larynx which house the vocal crds, is positioned between the trachea and the pharynx;
it is involved n wallowing breathing, and speaking.
- The pharynx extends from the nose to the uppermost portions of the trachea and
esophagus.
All of the following are pats of the respiratory system EXCEPT the:
A. trachea
B. bronchi
C. esophagus
,D. larynx
C. The esophagus is the only structure that is not part of the respiratory system, it is part of
the digestive system.
- The larynx houses the voice box; it also acts as a passageway for air to travel into the
lungs.
- The trachea connects the larynx to the lungs; splits into the right and left bronchi, which
divide into smaller passageways called the bronchioles.
What lab equipment would most likely be used to measure a liquid solution?
A flask
B. triple beam balance
C. graduated cylinder
D. test tube
C. In order to have accurate measurements, the use of a graduated cylinder would be the
best measurement equipment for a liquid solution.
- A triple beam balance measure the weight of an object in grams.
- A flask and a test tube are used to contain a liquid while being heated or stored.
An atom has 5 photos, 5 neurons, and 6 electrons. What is the electric charge of this atom?
A. neutral
B. positive
, C. negative
D. undetermined
C. The atom is negativity charged.
- neutrons have no charge
- protons have positive charge and electrons have negative charge equal in magnitude to
the positive charge of the proton.
All of the following are components of the genitourinary system EXCEPT:
A. the kidneys
B. the urethra
C. the rectum
D. the bladder
C. The genitourinary system is response for removing waste from the body through urine.
Which of the following best describes the structures found underneath each rib in
descending order?
A. vein, nerve, artery
B. artery, vein, nerve
C. vein, artery, nerve
D. nerve, vein, artery
C. Vein, artery, nerve
the neurovascular structure found under each rib in descending order is the vein, artery,
and nerve.
