Which is Not an example of a nonspecific immune response?
A. Inflammation.

D. Production of antibodies - ANSWER-D. In nonspecific immunity, the
response is immediate and antigen-independent, meaning that the invading
organism need not be identified by the body. In specific immunity, the response
takes some time and is antigen-dependent, as the production of specific
antibodies would be.
,Which organ system is primarily responsible for regulating electrolytes?
A. The endocrine system.
B. The urinary system.
C. The lymphatic system.
D. The nervous system. - ANSWER-B. The body's electrolytes must be
maintained at very precise concentrations. Excess water dilutes the body's
electrolytes, whereas water restriction concentrates them. The kidneys regulate
and help maintain the balance of water and electrolytes in the body.

Jeffery has contracted bulbar poliomyelitis, and it has affected the medulla
oblongata. The doctors warned the family that his condition is grave and death
may be imminent. What functions of the medulla oblongata have warranted
such a dire prognosis?
A. The medulla oblongata contains vital centers that control heart action, blood
vessel diameter, and respiration.
, B. The medulla oblongata contains neural connections of the reticular-activating
system.
C. The medulla oblongata contains the pineal gland, which controls the vital
centers.
D. The medulla oblongata contains the corpora quadrigemina, which controls
the neural transmission of impulses along the spinal cord. - ANSWER-A.
What are chemical messengers that control growth, differentiation, and the
metabolism of specific target cells called?
A. Hormones.
B. Neurons.
C. Glands.
D. Second messengers. - ANSWER-A.
Which of the following are tropic hormones? (select all that apply.)
A. Somatotropin.
B. Follicle-stimulating hormone.
