If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.

An X-ray is done to diagnose the position of bones in the body whether its broken or not or in right place or not. 
An X-ray machine is turned on to provide a visual of the bones showing bone condition. When the machine is turned on, X-ray travel through the body tissues, and due to the presence of calcium in bones, they absorb more X-rays, thus bones appear white against the black background of a radiograph. 
These white bones on the radiograph will show the position of bones whether it's broken or not.
So, both the visuals that is X-ray and drawing showing visuals (the bones appear white) contribute valuable data to the given situation.
