diagram
a membrane that seperates one thing from another
transparent, capable of being seen through
to walk through
a straight line through a fiqure from one corner to another corner
a picture drawn to explain an idea
to identify a disease through symtoms
having the power to be spread or to pass through
to drip through a small opening or to filter a liquid
continuing stubbornly without giving up
