  Colonies of yeast fail to multiply in water, but multiply in sugar solution. Give one reason for this.  

Answer:

                  When the colony of yeast is in water, it does not get nutrition. Sugar solution, on the contrary provides nutrition. As the yeast gets nutrition and thus energy, it grows and begin to produce buds. This is why colonies of yeast fail to multiply in water, but multiply in sugar solution.
