              artificial—made by people rather         microorganisms—living things
                than occurring naturally                that can only be seen with a
                                                        microscope
              artisans—people who are skilled at
                making things by hand                  molasses—a thick, sweet, brown
                                                        liquid made from raw sugar
              biomechanics—the scientific study
                of the way the body moves and          molds—receptacles in which
                functions                               materials are poured or pressed
                                                        to make casts
              bypasses—uses another route
                when the main one is blocked           molten—liquefied by heat

              cloned—created as an exact               nonporous—having a surface
                genetic copy of something else          without holes, which does
                                                        not allow liquid or gas to pass
              drafting—the process of                   through
                producing a technical drawing
                                                       particles—very small bits or
              essential—necessary and                   amounts of something
                extremely important
                                                       translucent—not completely clear
              fermentation—a chemical change            but transparent enough to allow
                that breaks something down and          light to pass through
                creates gases
                                                       vessels—hollow containers
              malfunction—failure to function
                normally                               volatile—likely to change rapidly
                                                        and unpredictably
              malleable—able to be shaped
                without breaking or cracking
