USING SCIENCE SKILLS
A student prepared two beakers with identical sprigs of a water plant as shown below. She placed one beaker in the shade and the other beaker beside a fluorescent lamp. She then systematically changed the distance of the beaker from the lamp. She counted the bubbles given off by each sprig of the water plant. Shown here is the graph of the data for the beaker she placed in the light.

25. 

Applying Concepts Look at Figure 8-4. If the student later tested the air bubbles collected in the test tube, what would she find they are made of? How do you know?
 

26. 

Analyzing Data Look at the graph in Figure 8-4. What do the student’s data show?
 

27.
