Water contains gas like carbon dioxide, but too much carbon dioxide makes the water acidic.
One example is the carbonated water drinks, it contains carbon dioxide that makes it acidic.

There would probably be fewer bacterial diseases that could attack humans because the appendages allow them to move or even in some cases protect them by having influence in their membrane creation and prevention of loss of water. The appendages allow bacteria to move and this certainly helps them in attacking humans or animals if they are of that type. Without the appendages they would probably also be easier to fight against with antibiotics.
