The jelly-like fluid that fills a cell is calledcytoplasm<span>. It is made up of mostly water and salt. </span>Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.<span>Cytoplasm has various functions in the cell. </span>
Most of the important activities of the cell occur in the cytoplasm. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
<span>Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.</span>
<span>There have been studies done that show using this technology to create milk makes the milk more dangerous. People who drink this milk are more likely to get prostate cancer, breast cancer and colon cancer. The technology also creates many toxins that can harm the cows and milk drinkers.</span>
Generally, the excretory system of the chickens is actually a biological system that usually removes excess of unnecessary materials from the body of the chicken. A function that eliminates the waste product of metabolism in the body such as liquids or gaseous wastes like urine, sweat and exhalation, these substances are usually toxic for the chicken body. There are only several organs that are considered part of the excretory system. It has also said that the system had a closed relationship with temperature in the body.
The most likely cause of the beak variation is the food source of the finch, the break size and shape was adapted to most likely have easier and better access to food. <span />
Group IV of the Periodic Table of the Elements contains carbon (C), silicon (Si) and several heavy metals. Carbon, of course, is the building block of life as we know it. So is it possible that a planet exists in some other solar system where silicon substitutes for carbon? Several science fiction stories feature silicon-based life-forms--sentient crystals, gruesome golden grains of sand and even a creature whose spoor or scat was bricks of silica left behind. The novellas are good reading, but there are a few problems with the chemistry.

CRYSTALLINE CREATURES? Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms.</span>
Indeed, carbon and silicon share many characteristics. Each has a so-called valence of four--meaning that individual atoms make four bonds with other elements in forming chemical compounds. Each element bonds to oxygen. Each forms long chains, called polymers, in which it alternates with oxygen. In the simplest case, carbon yields a polymer called poly-acetal, a plastic used in synthetic fibers and equipment. Silicon yields polymeric silicones, which we use to waterproof cloth or lubricate metal and plastic parts.
