When a Filament of Algae Is Illuminated with Light That

When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?

A) wavelength of light and the rate of aerobic respiration
B) wavelength of light and the amount of heat released
C) wavelength of light and the rate of photosynthesis
D) carbon dioxide concentration and the rate of photosynthesis
