Part B. Brief Constructed-Response Question
Directions
Use the information and diagram below to answer Number 26.
A scientist is conducting an investigation in which she sets up the experiment
shown here. The cellophane membrane acts like a cell membrane. Only water molecules can pass from the beaker into the bulb. Both water molecules and glucose molecules can enter the beaker from the bulb. Glucose molecules are larger than water molecules and, therefore, move across the membrane at a much slower rate.
After several days, the scientist observes the height of the liquid in the beaker. Predict whether the water lever will be higher, lower, or the same as it was at the beginning of the experiment. In your response, be sure to:
· provide reasons for your prediction
· use appropriate scientific vocabulary
Write your response on a separate sheet of paper.
