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.
SOLUTIONS. A solution is a mixture in which the different particles are tiny and are mixed completely evenly. Solutions are often made by dissolving a solid, such as sugar, into a liquid, such as water. The sugar is called the solute and the water is called the solvent.ARTICLE SIZE. SOLUTIONS. FIND OUT MORE. Almost everything is made of different substances mixed together. Things are only easy to recognize as mixtures if the PARTICLE SIZE of each substance is big enough to see. The flakes, nuts, and raisins in a bowl of cereal are a mixture that is easy to see.
