Another way that prototypes are classified is by the fidelity of the prototype, or the degree to which the prototype represents the appearance and interaction of the system.[ 4 ] A low-fidelity prototype is one that is quickly constructed to depict concepts, design alternatives, and screen layouts.
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. 1  solvent: the substance in which a solute dissolves to produce a homogeneous mixture. 2  solute: the substance that dissolves in a solvent to produce a homogeneous mixture.
In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent.A solution is saturated when there is too much solvent in the liquid i.e:The water cannot dissolve any more solvent because it is too much.
