<span>The correct answer is C) under base conditions, copper ions bind to the amino groups of proteins and change color. This test is a chemical one, which means it's testing the chemical properties of an object, specifically to detect peptide bonds. When these bonds are detected, an ion called copper II will bind (as the answer indicates), and will change the blue color of biuret into a violet color.</span>
