Thomas Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of the algal filament to different wavelengths of light. He added aerobic bacteria and found that these bacteria congregated in the areas illuminated by red and blue light. If you ran the same experiment without passing light through a prism, what would you predict?
A
There would be no difference in results
B
The number of bacteria would decrease along the entire length of the filament
C
The bacteria would be relatively evenly distributed along the length of the filament
D
The number of bacteria would increase along the entire length of the filament
Answer
The bacteria would be relatively evenly distributed along the length of the filament
