Polysaccharides are the most abundant carbohydrates. A polysaccharide molecule can contain thousands of glucose units. These highly complex carbohydrates include starches, cellulose, and glycogen. Starch is the usual form in which carbohydrates are stored as energy by plants.Plants can split starch into its simpler glucose units for use as energy when needed. Cellulose is known as a structural carbohydrate because of the fibers formed by its molecules.tarch is the usual form in which carbohydrates are stored as energy by plants.

When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or shooting star.
They are not exactly sure where it is going.. If an asteroid of this size were to hit Earth it could potentially ravage a continent, cause devastating tsunamis if it dropped in the ocean, or even plunge us into an ice age if the ash cloud it sent up blocked out the sun.n asteroid of just 30 metres could destroy a large city. If Spooky were to impact us or the Moon, the energy released would be measured not in kilotons like the atomic bombs that ended the Second World War, but in H-Bomb type megatons.
