Final answer:

The Benedicts test will be positive for starch digestion as it detects the presence of reducing sugars like glucose, which is a product of starch digestion. The Iodine test will be negative for starch digestion as it detects the presence of starch by forming a blue-violet color complex between amylose and iodine.

Step-by-step explanation:

The Benedicts test will be positive, indicating a presence of reducing sugars, while the Iodine test will be negative for starch digestion. The Benedicts test detects reducing sugars like glucose, which is a product of starch digestion. When glucose reacts with the Benedicts solution, it forms a red precipitate. On the other hand, the Iodine test detects the presence of starch by forming a blue-violet color complex between amylose (a component of starch) and iodine. Therefore, when starch is completely digested to glucose, the Iodine test will be negative.
