On a molecular level, the structure of chlorophyll is very similar to heme, which is a part of hemoglobin present in human blood. Heme, which is what makes blood appear bright red once exposed to oxygen, is bound to proteins forming hemoglobin.
Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people.
Lightning is usually associated with thunderstorms, and therefore is thought to be a spring and summer event. Yet lightning does occur during winter, and even during heavy snowfalls and blizzards. Winter lightning appears to be unusually powerful, associated with loud and long thunderclaps. Sometimes associated snowfalls can reach 3 inches an hour.
