ethylene can be produced from ethanol through ethylene. However, the amounts of sugar substances and grains are limited in the world. They are relatively expensive feedstocks for ethanol production, and ethanol competes with human food for these raw materials. This competition may lead the proce of grains and sugar to higher levels in the future. Furthermore, the economy of the ethanol production

ethylene, whose repeating unit is based on ethylene monomer. However, other structures do exist; for example, elements such as silicon form familiar materials such as silicones, examples being silly putty and waterproof plumbing sealant. Oxygen is also commonly present in polymer backbones, such as those of polyethylene glycol, polysaccharides (in glycosidic bonds), and DNA (in phosphodiester bon
1.Introduction
Every creaturein the nature strives against environmental change to survive.
Some cold-blooded animals such as chameleon or cuttlefish change their body's color to surrounding color, in case of some fishes like ase cucumber, they transform theirshape under stimuli, and some creature like flytrap, they rapidly response to stimuli to prey. Those surcical instinctsclude serial proc
