Which of the following are examples of homeostatic mechanisms? (Select all
that apply.)
a. Consuming excess calories to gain weight
b. Lifting weights to increase muscle mass
c. Shivering when the body temperature falls
d. Secreting insulin to decrease blood sugar concentration
e. Increasing heart rate when blood pressure is low
C,D,E
Homeostasis is defined as:
a.
Ability of human beings to keep body weight within normal limits
b.
Maintenance of a constant external temperature inside a room
c.
Ingestion of enough food to keep hunger pains from developing
d.
Tendency of the body to maintain a stable environment
D. tendency of the body to maintain a stable environment.
Where is the gastrocnemius vein in relation to the femoral vein?
a.Lateral
b. Distal
c. Superior
d. Ventral
B. Distal:
The gastrocnemius vein is found in the calf. The femoral vein is found in the
,proximal anterior thigh/pelvis. Since the gastrocnemius vein is found below the
femoral vein it is distal or inferior to the femoral vessel.
Which is NOT a type of protein?
a. Fibrous
b. Membrane
c. Globular
d. Unsaturated
D. Unsaturated
There are three types of proteins: fibrous, membrane, and globular. Fibrous or
structural proteins consist of collagen, elastin, and keratin. Membrane proteins
are interactive and anchored to a membrane. Globular proteins consist of
functional proteins like enzymes, hemoglobin, and insulin.
Which of the following is true regarding adipocytes?
a. They are involved in the secretion of glucose.
b. They are responsible for storing the fat that is found in adipose tissue.
c. They are critical in the digestive breakdown of fat.
d. They are the foundational element of muscles.
B: storage
Adipocytes are primarily seen in adipose or fat tissue. Their primary function is
the storage of fat. Adipocytes play a crucial role in maintaining proper energy
balance, storing calories in the form of lipids, and mobilizing energy sources in
response to stress. They are not involved in the digestion of fat or the secretion of
glucose, nor are they the foundational element of muscles.
What is the role of ribosomes?
a. Make proteins
b. Waste removal
c. Transport
d. Storage
A. A ribosome is a structure of eukaryotic cells that makes proteins.
Which of the following is an example of a chemical change?
, a. Releasing compressed gas to make a bottle-rocket launch
b. Adding water to clay to make slip
c. Crystalizing honey to make candy
d. Including baking soda in a recipe to make it less sour
D. A chemical change involves a chemical reaction and new substances are
produced.
Which of the following is exchanged between two or more atoms that undergo
ionic bonding?
a. Neutrons
b. Transitory electrons
c. Valence electrons
d. Electrical charges
C. Valence electrons
An ionic bond forms when one atom donates an electron from its outer shell,
called a valence electron, to another atom to form two oppositely charged atoms.
Which of the following anatomical terms is NOT part of the knee?
a. Medial collateral ligament
b. Patella
c. Lateral malleolus
d. Lateral meniscus
C. The patella is the medical term for the knee bone. The medial, lateral, and
anterior collateral ligaments help stabilize the knee with the help of the medial
and lateral menisci. The lateral malleolus is part of the ankle joint.
What is the typical way a solid would turn to a liquid and then to a gas?
a. Vaporizing, then melting
b. Melting, then freezing
c. Vaporizing, then freezing
d. Melting, then vaporizing
D. a solid turns to a liquid by melting, and a liquid turns to a gas by vaporization.
