Digestion. Digestion is the breakdown of food into simpler molecules that can be absorbed by the body. The digestive system is actually a long hollow tube called the gastrointestinal tract, or GI tract. The digestive system includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. Several major glands include the salivary glands, the pancreas, and the liver. The first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physical broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins.
clone. Noun. 1. A cell, group of cells, or organism that is produced asexually from a single ancestor. The cells of an individual plant or animal are clones because they all descend from a single fertilized cell. A clone may be produced by fission, in the case of single-celled organisms, or by budding, as in the hydra.
As such, human cloning means creating an identical human being with the aid of recent technology and genes of the donor. While the cloned individual will look like a carbon copy of the donor in terms of appearance, the personality of the two individuals could be world-apart from each other. While outward appearance can be cloned, the personality of an individual cannot be cloned.
