Use your knowledge of cellular respiration to select the best explanation for the observed changes in the color found inside the various test tubes below. Tube 1 Blue Tube 2 Yellow Tube 3 Green Elodea uses energy and cellular respiration to produce O2, No cellular respiration occurring, Elodea and snail produce O2 using cellular respiration Less O2 due to elodea cellular respiration that is also using CO2 in photosynthesis, More CO2 due to snail cellular respiration, balance of CO2 and O2 dur to elodea and snail presence Elodea uses energy and cellular respiration to produce O2, no cellular respiration occurring, cellular respiration that produces more CO2 than O2 Less O2 due to elodea cellular respiration that is also using CO2 in photosynthesis, More CO2 due to snail cellular respiration, Some CO2 present due to cellular respiration by both organisms but photosynthesis by elodea using CO2

A study was done to determine whether debridement surgery reduced knee pain. The output from statistical software analysis is shown to the right. The values are comparing mean knee pain scores for the placebo surgery (group 1) to the lavage arthroscopic surgery (group 2), assuming equal population standard deviations.
