A chemical imbalance in the body can cause the heart to stop pumping blood, which in turn will cause other tissues and organs to cease functioning. This observation supports the view that congenital defects can be life-threatening. all organisms are composed of cells. all levels of organization within an organism are interdependent. chemical molecules make up cells. blood has magical properties.

all levels of organization within an organism are interdependent.
