Wind is plotted in increments of 5 knots (kts), with the outer end of the symbol pointing toward the direction from which the wind is blowing. The wind speed is determined by adding up the total of flags, lines, and half-lines, each of which have the following individual values: Flag: 50 kts. Line: 10 kts.
Save. Whether you bite into an apple, steak or dish of ice cream, youâre sure to get plenty of one type of element: carbon. Because carbon is present in all known forms of life, every food we eat contains carbon. Carbon is unique in its ability to form large, diverse molecules because of the way it forms electronic bonds with other atoms. The chemical bonds carbon forms allow it to form long molecular chains essential to life as we know it.
Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all forms of carbon-based life, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen.arbon is the fourth most abundant chemical element in the universe by mass after hydrogen, helium, and oxygen. Carbon is abundant in the Sun, stars, comets, and in the atmospheres of most planets. Some meteorites contain microscopic diamonds that were formed when the solar system was still a protoplanetary disk.
