Answer 1

Answer:

In test-tube A, the boiled rice contains starch. When we add 1-2 drops of iodine, the combination turns in the shade of blue-black. This indicates the presence of starch in the test tube A.

In test-tube B, the starch of rice converts into sugar on digestion. Thus, the colour of iodine will not change.
