Section 1: 1. Many people have received the measles vaccine so that they will be protected from getting the measles, which can be very serious or even fatal. How does receiving a measles vaccine help to protect a person from getting the measles? A) The vaccine prevents the virus that causes the measles from entering the body. B) The vaccine inserts genes into body cells to fight the virus that causes the measles. C) The vaccine causes the immune system to produce antibodies to the virus that causes the measles. D) The vaccine adds a chemical to the body that is poisonous to the virus that causes the measles. 2. After an initial Infection B-cells recognize the measles virus. How is this helpful in human immune response? A) The B-cells produce antibodies more quickly if the measles virus is encountered again. B) The B-cells use this recognition to defend the body against other pathogens, soch as bacteria C) The B-cells more quickly recognize and respond to any other virus that invades the body. D) The B-cells transfer this recognition to T-cells,which will then devour the viruses 3. A florist gets a thorn stuck in her skin after arranging flowers. She notices that the area of skin around the thom is turning red and becoming puffy The area is also painful to touch and feels warm. What type of immune system response did the florist observe? A) specific response B) antibiotic response C) antibody response D) nonspecific inflammatory response

Answer 1

1. C) The vaccine causes the immune system to produce antibodies to the virus that causes the measles.Receiving a measles vaccine helps protect a person from getting the measles by stimulating the immune system to produce antibodies against the virus. These antibodies help the body recognize and fight off the virus if it is encountered in the future.2. A) The B-cells produce antibodies more quickly if the measles virus is encountered again.After an initial infection, B-cells retain a memory of the measles virus, allowing them to respond more rapidly and effectively by producing antibodies if the virus is encountered again.3. D) nonspecific inflammatory responseThe symptoms described—redness, puffiness, pain, and warmth—are characteristic of a nonspecific inflammatory response. This is the body's immediate reaction to injury or infection, aimed at preventing further damage and starting the healing process.
