1. Complex carbohydrates

2. Simple carbohydrates

3. Proteins

4. Lipids

The answer is

1. Complex Carbohydrates

Explanation:

You can use an iodine solution to detect the presence of complex carbohydrates. The yellow-orange iodine will turn blue-black as it reacts with starch. (The iodine solution will show no reaction with simple carbohydrates or sugars.)

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
