Describe an experiment to test the effect of changing the acid concentration. You should include: • a diagram showing how you could catch the gas from the reaction
• how you could use the
collected gas to measure the rate of the reaction, not just how long the reaction lasts
• how you would decide which acid concentration gave you the fastest reaction

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

the answer is 100% density i've answered this question before and done the quiz myself.
