Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non- germinating. A germinating seed is one from which a plant has started to grow. A non-germinating seed is usually dry and a new plant has not yet
emerged. The data that she gathered are displayed in the graph.
In addition to carbon dioxide, which of the following should Callie expect the seeds to give off as a waste product from performing cellular respiration?
