A side effect of these chemical reactions is a lot of heat. The fact that the chemical reactions in a fire generate a lot of new heat is what sustains the fire. Many fuels burn in one step. Gasoline is a good example. Heat vaporizes gasoline and it all burns as a volatile gas. There is no char. Humans have also learned how to meter out the fuel and control a fire.
Researchers just mapped their genome for the first time to find out. By Paca Thomas. Bowhead whales can live more than 200 years, and they rarely succumb to cancer or disease. Searching for clues about their longevity, researchers just mapped their entire genome. Watch more in the video above.
How long do Whales live? Whale Lifespan. Some whales have a lifespan similar to humans, particularly the blue and the fin whales as they reach up to 85 years old. The life cycle of a whale varies from type to type, but the best known species have the following: 1  Humpback whales live about 45-100 years. 2  Gray whales live 25 to 80 years. 3  Blue whales live over 80-90 years. 4  Fin whales live about 85-90 years. 5  Minke whales live 40 to 50 years. 6  Sperm whales live about 75 years.
