Heterogenous mixtures are composed of more than one chemical substance and can be visually distinguished from one another. Trail...
Um ?snake venom is a mixture of proteins...some toxic—poisonous—and some not. By analyzing the DNA—the genetic material—of the proteins, the researchers could focus on the toxic genes, and use them to trace the evolution of snake venom...and, from this, the evolution of snakes....

Amixtureis what you get when you combine twosubstancesin such a way that nochemical reactionoccurs between the components, and you can separate them again. In a mixture, each component maintains its own chemical identity. Typically mechanical blending combines components of a mixture, although other...
