Since 2005, there have been several outbreaks of foodborne illnesses that have made people sick and resulted in the deaths of some. Why don't scientists simply conduct intervention studies rather than those that are epidemiologic when some foods are thought to be contaminated so that they can be sure which foods are at fault and remove them from the food supply promptly?

Question 2

_____ transports copper.
 a. Hematocrit
  b. Ceruloplasmin
  c. Cytochrome c oxidase
  d. Glutathione peroxidase

Answer to Question 1

Conducting intervention studies would require that scientists give contaminated foods to the research subjects. Doing so would result in some subjects becoming ill and perhaps dying. Because of the risk of becoming ill, this is not an acceptable scientific approach. Thus scientists rely on epidemiologic studies, which may suggest an association but do not prove cause and effect.

Answer to Question 2
