Answer:

In between the A bands is a light area where there are no thick myofilaments, only thin actin filaments. These are called the I Bands. The dark bands are the striations seen with the light microscope. When a muscle contracts the light I bands disappear and the dark A bands move closer together.

The answer is 3468 kcals. Protein and carbohydrates both contain 4 calories per gram, while fat provides 9 calories per gram.
