You can test to see if an enzyme is completely saturated by adding more of the substrate.
Hope this helped :)
C. The small rocks are mechanically weathering the larger rocks and erosion is morning the pieces downstream

They are involved in a chemical digestion.
Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.
