The purpose of these two investigations was to show gas exchange during photosynthesis. In 3-5 sentences explain why two investigations are needed to show gas exchange during photosynthesis?

Answer 1

Two investigations are needed to show gas exchange during photosynthesis to ensure the reliability and accuracy of the results. The first investigation can measure the uptake of carbon dioxide or the release of oxygen, demonstrating the gas exchange process in a controlled setting. The second investigation, possibly conducted under different conditions or using different methods, can serve as a validation of the first by confirming the results and addressing any potential variables or environmental influences. Together, these investigations provide a more comprehensive understanding of the gas exchange dynamics in photosynthesis, enhancing the overall findings.
