Question

what evidence would you need to support the claim that a sample contains a simple sugar?
○ a a biuret test result that is blue
○ a a biuret test result that is purple
○ a a benedict’s test result that is blue
○ a a benedict’s test result that is yellow, orange, or red

Explanation:

To determine if a sample contains a simple sugar (reducing sugar), Benedict's test is used. A positive Benedict's test (indicating presence of simple sugars) shows colors like yellow, orange, or red (depending on sugar concentration), while a blue result is negative. Biuret test is for proteins (purple result for positive). So the evidence for simple sugar is a Benedict's test result with yellow, orange, or red.

Answer:

a Benedict’s test result that is yellow, orange, or red
