Cells Cell (biology), basic unit of life. Cells are the smallest structures capable of basic life processes, such as taking in nutrients, expelling waste, and reproducing. All living things are composed of cells. Some microscopic organisms, such as bacteria and protozoa, are unicellular, meaning they consist of a single cell. Plants, animals, and fungi are multicellular; that is, they ar

Polar Forces Polar forces are always in the midst of scientific study. The physics surrounding the movements of our home, the earth, revolves around opposing forces. With such importance to science, opposing forces could quite possibly be a factor in dealing with dating, and couple compatibility. The common phrase, “opposite’s attract,” in reference to dating, assumes that people’s perso
