GED Science Review: Health and Disease

Questions:
Questions 1 through 3 refer to the following paragraph and map.

In the 1990s, the Food and Drug Administration (FDA) approved a vaccine against Lyme disease, a bacterial infection transmitted to human through the bite of a deer tick. The three-dose vaccine was approved only for adults. It worked by stimulating the immune system to produce antibodies that destroy the bacteria. In studies involving 11,000 people, the vaccine was shown to be about 78 percent effective. Scientists advised people who work or play in wooded or overgrown areas where Lyme disease and deer ticks are common to get the vaccine. In 2002, the vaccine was discontinued.



Directions: Choose the answer to each question.


  1. Which person would most benefit from Lyme disease vaccination?
    • A woman who lives on a ranch in the Great Plains region
    • a young child who lives in a major city in New England
    • a woman who lives in a wooded area of the Upper Midwest
    • a man who works on a cargo ship that departs from the Southeast
  2. Which is the most likely hypothesis for the investigations described in the passage?
    • Lyme disease is more common in New England than other regions.
    • Lyme disease is transmitted to humans through the bite of deer ticks.
    • People infected with Lyme disease produce more antibodies against it.
    • People who receive the vaccine are less likely to develop Lyme disease.

      Directions: Write your answer on a separate sheet of paper.
  3. Some scientists think that weather conditions may affect the risk of Lyme disease. Deer ticks are less likely to be active when the weather is dry. When ticks are active, they climb up stalks of grasses and other plants and wait for a large mammal to pass by. The ticks can then jump onto and infect people or animals. State a hypothesis that would allow scientists to test this relationship. Describe how the hypothesis may be tested
Answer:

  1. a woman who lives in a wooded area of the Upper Midwest
  2. People who receive the vaccine are less likely to develop Lyme disease.
