Which situation would be most likely to cause a dna mutation? a. a maple tree becomes dormant to prevent water loss during a drought. b. a culture of cells is placed in a chamber and exposed to high pressure for 10 hours. c. a wood frog in a lake is exposed to temperatures below 0°c during the winter months. d. a person spends one hour each day under the ultraviolet rays of a tanning bed.

The correct answer is option D, that is, a person spends one hour each day under the ultraviolet rays of a tanning bed.  

The UV, or ultraviolet light from the sun, us a non-ionizing radiation that can cause DNA mutations. It does this by making the formation of pyrimidine dimers. Direct destruction of DNA can take place when DNA directly absorbs a UVB photon.  

The UVB light makes thymine base pairs next to each other in the genetic arrangements to combine together in the pyrimidine dimers. It has been shown that the patches of skin chronically exposed to sunlight exhibit up to 10 times more cancer-producing gene mutations in comparison to the skin, which is usually safeguarded from the sun.

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]
