Water molecules have covalent bonds. Each molecule consists of two hydrogen and oxygen covalent bonds. However, when water molecules are placed together, as they are normally, the hydrogen atoms in each molecule can form hydrogen bonds with the oxygen atom of other molecules.
Then the model will become useless. originally the bottle should be air tight only tubes connected to the balloons, so that pressure can be shown when you adjust the plastic sheet in the bottom of the model. but now if there's a hole, air can move freely in or out the bottle and the model will not be able to show anything that occurs during respiration
The optimal pH can be measured by looking at enzyme activity verses pH. Enzyme activity will increase up to a certain pH; above that pH, the enzyme activity will begin to fall.
