A plough or plow (US; both / p l aÊ /) is a tool or farm implement used in farming for initial cultivation of soil in preparation for sowing seed or planting to loosen or turn the soil. Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors.
Nonpolar molecule. Definition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.However, the polar bonds in nonpolar molecules are arranged symmetrically causing dipoles to cancel out each other. As a result, nonpolar molecules have no net dipole.efinition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.
So, a molecule is nonpolar when the bond is ionic (which is a bond formed by magnetic forces) or when the molecules are similar in electronegativity, thus sharing the electrons equally, maintaining an equal charge for both sides of the new combined covalent molecule. This is applied in biology; water, H20, is covalent.n the context of biology, polar molecules attract polar molecules and non-polar molecules attract non-polar molecules.
