1. is made up of

     • containing
       • matter
         • is
           • anything that takes up space and has mass
             • has
               • many diverse forms
                 • such as
                   • solid, liquid, and gas
         • composed of
           • living

               • elements
                 • substance that cannot be broken down to simpler susbstance with different properties
