5.) Please provide an explanation thank you very much!

In the lab, you are given four samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), and RNA. The samples are in test tubes marked 1, 2, 3, and 4, but you don’t know which compound is in which tube. You are instructed to identify the contents of each tube based on the information given in a-c.

a. In your first test, you try to hydrolyze a portion of the contents of each tube using enzymes. Hydrolysis occurs in all tubes except tube 3.

c. The last test you perform shows that the compound in tube 1 contains a high percentage of phosphate.  

Based on these data, identity the sample in each tube below.

Tube 1:

Tube 2:
