Below are data from a study (described in Module 6.3) conducted by Michael Lesser,Marc Slattery,and colleagues.The rate of photosynthesis (Graph A) and the amount of carbohydrate present (Graph B) ,an indication of photosynthetic production of sugars,were determined in sponges exposed to current temperature and pH (control) or to one of three test groups: the expected pH in 2100 (test group 1) ,the expected temperature in 2100 (test group 2) ,or both (test group 3) . (Note: Significant difference between groups is denoted by a different letter above the bars; if two groups share the same letter,they are not statistically different.)
-What would the control conditions be for this experiment?
