Many people have received the measles vaccine, which can prevent this very serious or even fatal disease. How does receiving a measles vaccine help to protect a person from getting the measles?

• The vaccine inserts genes into body cells to fight the virus that causes the measles.
• The vaccine adds a chemical to the body that is poisonous to the virus that causes the measles.
• The vaccine causes the immune system to produce antibodies to the virus that causes the measles.
• The vaccine prevents the virus that causes the measles from entering the body.

Plaque can build up along the walls of the arteries for many years, which statement describes a result of plaque building up in the arteries of an individual?

• The arteries become more elastic.
• The heart beats slower.
• An increase in the blood flow to the affected area of the body occurs.

Mary feels sick for a week and decides to go to the doctor. The doctor tells her that she has a viral infection and does not prescribe antibiotics to treat her illness. Within a couple of days Mary is feeling better. Which statement best describes Mary's path to recovery?

• Mary was already feeling better and didn't need to go to the doctor's office.
• Antibiotics produced by Mary's body stimulated her immune system to produce enough antibodies against the virus and destroy the viral infection.
• The nonspecific immune response destroyed the virus through inflammation two weeks after Mary went to the doctor's office
• The specific immune response produced antibodies that rid her body of the viral infection after it learned the properties of the viral molecule.
