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.
solution. in chemistry, homogeneous mixture mixture,in chemistry, a physical combination of two or more pure substances (i.e., elements or compounds). A mixture is distinguished from a compound, which is formed by the chemical combination of two or more pure substances in a fixed, definite proportion......olution, In most common solutions, the solvent is a liquid, often water, and the solute may be a solid, gas, or liquid. For example, syrups are solutions of sugar, a solid, in water, a liquid; household ammonia is a solution of ammonia gas in water; and vinegar is a solution of acetic acid, a liquid, in water.
