Colligative properties are those properties of solutions that depend on the number of dissolved particles in solution, but not on the identities of the solutes. For example, the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water.
Shares & Saves. Save. DNA testing evolved from the study of genetics, which began in the late 1800s when Gregor Mendel first studied the phenomenon of inherited traits in pea plants. His work laid the foundation for the discovery of DNA, or deoxyribonucleic acid, the molecules that contain our genetic makeup.
But such innovations are rare. Theranos, a company founded by Stanford sophomore Elizabeth Holmes in the fall of 2003 (she dropped out a few months later) has generated a lot of buzz for developing a revolutionary approach to the blood test.Theranos' innovation theoretically does clinical lab testing faster, cheaper, and, in some ways, better.ut such innovations are rare.
