The reactants are __glucose and fructose 7. The products are ___sucrose and ___water 8. Would you say that glucose or sucrose is more complex? (circle one) Why? Glucose can’t be broken down but sucrose can be broken down. 9. What would you call the process that is occurring? 10. What is the elephant getting when the bond is broken in sucrose? 11. Starch is a complex carbohydrate found in plants which contains approximately 200 glucose molecules. Predict the function of starch and explain why.

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
