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.
Asteroids headed for Earth are scary. So get to know them a little! You can use the Impact: Earth! calculator to see what kind of damage an asteroid will cause. It's totally not as scary when you crunch the numbers. The Impact: Earth! calculator was developed by a Purdue University research team and it basically lets anyone calculate the damage an Earth-bound asteroid will cause. You'll have to fill in the basic info of your presumed asteroid like how big it is, how dense it is, the angle of entry and the location of its hit.
