A sleepy driver rounds a bend and sees a deer standing in the road. The driver snaps to attention and applies the brakes, averting the accident, because his brain was aroused by the Reticular Activating system(RAS).

Explanation:

Reticular activating system (RAS) is a part of brain that filters the sensory signal that tries to reach our brain.However the olfactory Signal do not pass through it .Reticular activating system is located at the brain stem little above the spinal column.This is an extremely important part of the brain because it sorts various sensory signals into important and non-important ones.RAS allows only those information into the brain that needs immediate attention of the conscious mind.Hence it is responsible for sudden wakefulness.Our sensory organs perceive thousands of information each second and direct them towards the brain.If RAS was not there then our brain would have reached a state of confusion every minute and might have failed to give proper response to any of the stimulus.In the given situation, the sudden sight of the deer acted as a threatening stimulus.This information needed immediate attention of the driver's conscious mind and his brain was thus aroused by the RAS.

Answer from: Quest

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
