1. Our  reference dyes were slightly bigger than our experimental dyes, and we had two yellow bands. Our experimental dyes also contained a brown color, which the reference dye didn't have,which was from a brown m&m.
2. The citrus red 2 would have migrated similarly to our yellow dye, because that one traveled the most, being the shortest. The citrus red 2 is composed of the least molecules. The Betanin would have traveled similar to our orange dye, which traveled the least because it was the longest.
3. Adding food coloring to dog food would make it look more nutritious and better for the dog. Dog owners wouldn't want to choose a colorless food that doesn't look good for their dog.
4. FD&C Dye: Red 40; Color: Red; Natural Alternative:  Boiled cranberries; Source of Natural Dye: Cranberries. 
Artificial food color might look more vibrant and fresher than natural food colors. 
5. The size of the band controlled the distance in how much the solution migrated. The longer the molecules were, the less it migrated. 
6. The electricity helps move the dyes through the gel. Also, the gel itself has holes and pores for the solution to move through. 
7. When electricity pushes the solution down the gel, bigger molecules take longer to move through the pores and holes, and smaller molecules move through them faster. The further down the gel the band is, the shorter the band is. 
8. 5000 daltons will be closest to the starting point. 2000 daltons will be second closest from the starting point, but maybe twice as far as 5000 daltons is. 1000 daltons would be even further away, and 600 daltons would be furthest away.
