in the lungs
B) a decrease in the number of pathogens in the
body
C) a decreased secretion of hormones by certain
glands
D) an increase of carbon dioxide in the cells of the
body
4. Cells of the immune system are able to respond to the
presence of invading organisms because they
recognize the
A)
B)
C)
D)
antigens present on the invaders
antibodies present in invading pathogens
DNA pattern in the nuclei of viruses
antibiotics released from microbes
A function of another type of white blood cell is to
A) prevent the loss of blood from a wound
B) produce specialized molecules that mark
invaders
C) increase the number of red blood cells in the
blood
D) cause gene mutations that will increase immune
responses
8. Which diagram best represents a blood cell from a
person with type O blood?
5. An infection in the body might result in a sudden
A) decrese in the activity of antigens produced by
the mitochondria
B) decrese in the amount of DNA present in the
nuclei of cells
C) increase in the activity of white blood cells
D) increase in the number of red blood cells

body.
The cells labeled A and B are examples of cells known as
A) guard cells
C) white blood cells
B) reproductive cells
D) specialized skin cells
10. Base your answer to the following question on the information and diagram below.
A technician needed to determine the blood type of four individuals. To do this, the technician set
up four slides, one for each individual. The technician placed a drop of antibody A serum and a
drop of antibody B serum on each of four slides. The technician mixed a drop of blood from each
individual into the anti-A and anti-B serum on a different slide. The results of the four tests are
shown below.
Which slide contains blood from the individual who has antigen A, but not antigen B?
A) 1
B) 2
C) 3
D) 4

Base your answers to questions 11and 12 on "
the blood-typing chart below and on your knowledge of biology.
"

A) A
B) B
C) AB
D) O
12. Which antibodies, if any, are in the plasma of individual 2?
A) anti-A, only
C) both anti-A and anti-B
B) anti-B, only
D) neither anti-A nor anti-B
13. A student received a flu shot in the fall. During the
flu season, the student caught a cold. The most likely
reason the vaccine he received did not prevent the
cold was that
A) his illness was not caused by a pathogen
B) he did not get the vaccine at the right time of
year
C) his body produced antibiotics in response to the
vaccine
D) the vaccine he received contained only flu virus
antigens
15. A student infected by a common cold virus ran a
low-grade fever. After a few days, the student's
temperature returned to normal and the student was
free of cold symptoms. The fever served as
A)
B)
C)
D)
an antigen in the circulatory system
an immune response to a pathogen
a biological catalyst
a weakened pathogen
16. Every time a child visited a cousin who has two cats,
the child's eyes turned red, itched, and began to
water. Then, the child began to have trouble
14. An organ, such as a kidney, used for transplant needs
breathing. It is most likely that the child reacted this
to be tested for compatibility with the person who is
way because
to receive the organ. If this is not done, the
A) normally harmless cat antigens stimulated the
A) donated organ might attack the body
immune system
B) donated organ might attack the immune system
B) it is difficult for the respiratory system to filter
cat antigens out of the inhaled air
C) immune system might attack its own body cells
C) cat antigens are a health hazard, since they
D) immune system might attack the donated organ
always cause disease
D) cat antigens stop the immune system from
making antibodies, so bacteria cause these
responses

19. A 6-year-old child ate a peanut butter sandwich at
snack time in school. Five minutes later, her throat
became swollen and she collapsed. This allergic
reaction occurred because her body
