In the hydrolyzing polysaccharides with saliva, the instructor followed the steps in the order listed below: prepared two tubes with starch (tubes 1 and 2); tested samples from both tubes with the IKI test and the Benedict's test; added saliva to tube 2 both tubes were immediately placed in a 37°C water bath for 15 minutes; • removed the tubes, and tested samples from both tubes with IKI and the Benedict's. Which of the following are correct about the results of the tests for a group of students who did all of the steps correctly. If hydrolysis can occur, assume that all polymers are hydrolyzed. Select ALL of the possible answers. O Tube 1 should have a negative IKI test. O Tube 2 should have a positive Benedict's test. O Tube 1 should have a negative Benedict's test. O Tube 2 should have a positive IKI test. O Tube 2 should have a negative IKI test. O Tube 2 should have a negative Benedict's test. O Tube 1 should have a positive IKI test. O Tube 1 should have a positive Benedict's test.
