The liquid should be neutralized.
In the stomach, the pH value is around 2.0, which is because of the hydrochloric acid in the stomach. It can provide a optimum pH for the stomach enzymes.
However in the small intestine, the enzymes there works in a optimum pH of around 8.0, therefore the liquid must be neutralized before going into the small intestine, or else the enzymes in the small intestine will be denatured due to extreme pH.
Neutralization can be done by the sodium hydrogen carbonate, which is a alkali produced in small intestine.

The question is simply asking for the volumetric flow rate of the water in the river. It<span> is the volume of fluid which passes per unit time. It has units of m^3 /s. We calculate as follows:
Q = 750 m^2 (4 m/s ) = 3000 m^3/s
Hope this answers the question. Have a nice day.</span>
D. It allows a variety of substances to dissolve in and around cells.
Explanation:
The shell of hydration is important to life because it allows a broad range of substances to dissolve in and around the cells.
- The shell of hydration allow for water to dissolve a wide range of substances and disperse them uniformly in it.
- Water serves a solvent capable of dissolving a wide range of substances because it forms a hydration shell round them.
- This allow for materials to be in solution around the cell.
- Diffusion and osmosis can readily now take place.
