just olya [345]
The answer would be 
D) Kicking a soccer ball
Skeletal muscle controls just about all of your body movement. When you are digesting lunch you are not moving. When your body is moving blood through arteries, your body is not moving. When your heartbeat is increasing you are not moving. But when you move to kick a soccer ball you are moving. Thats why this action would be completed by skeletal muscles.
