If the cell membrane does not function normally it allows abnormal movement of substance in and out of the cell, lets take for example the movement of water of plasma membrane allows water to get in into the cell more than what is needed it might cause the bursting of the cell or if it allows water from the cell to get out and leaves only solute within this will cause shrinking of the cell wherein both conditions are abnormal
I would go with 6 because if there would to be an emergency there would be enough water there.

Fresh food restaurants like sushi restaurants, if it's not made the second the server says what the customer wants, they can get food poisoning. Some seafood restaurants have a time limit on how long they can take to make food.
Same with subway & bakeries, it has to be fresh, no waiting.
