Questions and Answers
  • 1. 
    Base your answer on the information and diagram below and on your knowledge of biology. Starch turns blue black in the presence of a starch indicator. Dialysis tubing tied at both ends and containing starch solution is placed in a beaker of water. Yellowish brown starch indicator is then added to the water. What will the solutions in the beaker and the tubing look like after 20 minutes?
    • A. 

      The indicator solution in the beaker will be blue black and the starch solution in the tubing will not change color.

    • B. 

      The starch solution in the tubing will be blue black and the indicator solution in the beaker will not change color.

    • C. 

      Neither the indicator solution nor the starch solution will be blue black.

    • D. 

      Both the indicator solution and the starch solution will be blue black.
