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.
Thunderstorms can happen anywhere and at anytime as long as the weather conditions are right. These storms most frequently form within areas located at mid-latitude where warm moist air front collides and border cool air fronts. Compared to more active parts of the United States, thunderstorms are relatively rare in Alaska, New England, North Dakota, Montana, and other northern states where the air is generally cold.
