EVERYDAY SCIENCE

Detailed explanation-1: -Muscles are responsible for all locomotion in the body. This movement occurs through the contraction of the muscle. One would have no way to move without skeletal muscle; therefore, the answer is true.

Detailed explanation-2: -Without the bones, there would be no structure or shape to the body. Our bodies would be like jelly. We would not be able to walk and run like how we are able to now.

Detailed explanation-3: -Allows movement: Your skeleton supports your body weight to help you stand and move. Joints, connective tissue and muscles work together to make your body parts mobile. Produces blood cells: Bones contain bone marrow. Red and white blood cells are produced in the bone marrow.

Detailed explanation-4: -No way. Without bones you’d be just a puddle of skin and guts on the floor. Bones have two purposes. Some, like your backbone, provide the structure which enables you to stand erect instead of lying like a puddle on the floor.

Detailed explanation-5: -A person would be unable to move or even stand up straight if they didn’t have any muscles. The heart would not be able to beat and the digestive tract could not do its job. There are basically three different types of muscles in the human body, notably smooth, cardiac and skeletal muscles.
