The hamburger and tuna tested negative for starch. expalin why foods of this type would not contain starch.

In order to understand this question, remember that starch is a complex carbohydrate or a polysaccharide . This means that it's sugars are more molecularily complex and thicker. Starches have one primary function, and that is to store excess glucose for *plants*. Starches are not produced by animals, because just like humans, fish and cows have a liver that will store glucose with our own polysaccharide; Glycogen. 

Yes you do , which is cool

Tbh i think it’s an odd coincidence, maybe you “predicted the future” it’s happened to me before but i wouldn’t doubt it if you did but i hope you have fun
