Review the section "Investigating Life: Solar-Powered Salamanders." The researchers added CO2 tagged with a radioactive isotope of carbon to a solution surrounding salamander eggs and incubated some eggs in the light and some in the dark. After two hours, the researchers measured the amount of radioactivity in the eggs and found that the eggs incubated in the light had more radioactive carbon than the eggs incubated in the dark. What process occurred in the eggs incubated in the light but not in the eggs incubated in the dark to account for the higher amount of radioactive carbon?
A) photorespiration
B) photosynthesis
C) diffusion of CO2
D) cellular respiration that produces CO2
