Nieto-Gomez explains combinatorial evolution as a series of innovations‚ accelerated by the rate of technological advancements that produce infinite combinations of possibilities on society that can and are unpredictable (p. 2). These combinations or recombinations can have positive‚ as well as negative impacts. On the darker side of combinatorial evolution are horrific events such as the Oklahoma City bombing attack of the Alfred P. Murrah Federal Building on April 19‚ 1995. Convicted for the

Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food.

IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in
