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.
Solubility Review. A solution is a mixture of two or more substances. The solute is the substance being dissolved, and the solvent is the substance that the solute is dissolved in. The solvent is often water. The process of creating a solution is called solvation.Not everything can dissolve in water â for example, oil will not dissolve in water.Whether or not a solute will dissolve in a particular solvent depends on the attraction between molecules.he solvent is often water.
