G) A) and B)

Question 3

The nervous system and endocrine system control the body's functions by

Accepted Answer

A)   maintaining a constant level of nerve impulses.
B)   sending out messages by nerve impulse and hormones.
C)   responding only to the internal environment.
D)   stimulating the body's reproductive organs.
E)   maintaining a constant level of hormones in the blood. The endocrine system and the nervous system are the control systems of the body, both responding to the internal and external stimuli. The nervous system sends messages through nerve impulses, and the endocrine system through hormones.F) All of the above
G) None of the above

Question 4

In the figure shown here, the tissue indicated by "3"

Accepted Answer

A)   lends strength to and supports the joint.
B)   cushions the bones of the joint.
C)   attaches muscle to the bones.
D)   provides a smooth surface on the ends of bones.
E)   causes the movement of the joint. The tissue indicated by "3" is adipose tissue. Adipose cells have very little matrix but are filled with triglycerides. In addition to their function in the storage of fat as a long-term energy source, adipose tissue acts to insulate and cushion parts of the body.F) A) and D)
G) A) and E)

Question 5

Columnar cells with small projections called microvilli that line the intestine are a type of

Accepted Answer

A)   muscle tissue.
B)   epithelial tissue.
C)   connective tissue.
D)   squamous tissue.
E)   nervous tissue. Cell shape is one of the characteristics used to name epithelial tissues. Microvilli are processes of the cell membrane which increase the surface area of the columnar cells for digestion and absorption.F) B) and D)
G) C) and D)

Question 6

Skeletal muscle and cardiac muscle are similar in that they are both

Accepted Answer

A)   under voluntary control.
B)   under involuntary control.
C)   made of highly branched cells.
D)   striated.
E)   made of long parallel cells.F) A) and E)
G) C) and D)

Question 7

Blood is classified as connective tissue because of its fluid matrix called plasma.

Accepted Answer

A) True 
 B)False

Question 8

Homeostasis maintains various levels within a narrow range only if environmental conditions do not fluctuate much.

Accepted Answer

A) True 
 B)False

Question 9

Collagen fibers and elastic fibers are produced by

Accepted Answer

A)   squamous epithelium.
B)   neuroglia.
C)   fibroblasts.
D)   platelets.
E)   adipose. These fiber types are characteristic of connective tissue and are part of the matrix. They are produced by a type of cell called a fibroblast.F) A) and C)
G) A) and E)

Question 10

Which of the following lists the levels of biological organization in order from simplest to most complex?

Accepted Answer

A)   cell, cardiac muscle, heart, cardiovascular system, human
B)   cardiac muscle, cell, human, heart, cardiovascular system
C)   human, heart, cardiovascular system, cardiac muscle, cell
D)   cell, heart, human, cardiovascular system, cardiac muscle
E)   heart, human, cell, cardiac muscle, cardiovascular system The simplest level of organization of living things is the cell. Tissues are composed of cells, organs are composed of tissues, and organ systems are composed of organs.F) D) and E)
G) A) and B)

Question 11

Glands are often composed of muscle tissue.

Accepted Answer

A) True 
 B)False

Question 12

The respiratory system would respond to a change in

Accepted Answer

A)   oxygen levels only.
B)   blood sugar levels.
C)   the body's fluid levels.
D)   oxygen and carbon dioxide levels.
E)   body temperature. The respiratory system brings oxygen into the body and rids the body of carbon dioxide. Therefore, it responds to changes in the levels of oxygen and carbon dioxide in the blood. The other stimuli listed are responded to by other systems.F) A) and D)
G) C) and E)

Question 13

If your body is dehydrated, the control center in the brain will stimulate the release of a hormone which causes the reabsorption of water into the blood during urine formation. When the control center senses that enough water is reabsorbed, it will stop the release of the hormone. This is an example of

Accepted Answer

A)   a negative feedback mechanism.
B)   a positive feedback mechanism.
C)   response to external stimuli.
D)   lack of control over homeostasis.
E)   a combination of negative and positive feedback. This is an example of a negative feedback mechanism because the change from normal is lessened and the loop shuts itself off.F) A) and C)
G) D) and E)

Question 14

_____ carry signals to the cell body of a neuron, while _____ carry signals away from the cell body.

Accepted Answer

A)   Neuroglia; dendrites
B)   Axons; dendrites
C)   Intercalated disks; neuroglia
D)   Dendrites; axons
E)   dendrites; neuroglia The neuron is the functional cell of nervous tissue, producing the characteristic nervous impulse. The processes leading to the cell body are the dendrites and the process leading away is the axon. Neuroglia are the supportive cells of nervous tissue.F) A) and B)
G) C) and D)

Question 15

A group of similar cells and the surrounding materials that work together to perform a specific function are

Accepted Answer

A)   organelles.
B)   tissues.
C)   molecules.
D)   organs.
E)   organ systems.F) A) and D)
G) D) and E)
