Dr. Alexander is a scientist who studies a certain type of fly. In his studies, he came across information that says that the fly doesn't need any calcium in its diet. This question interests him because he doesn't think it is true. He decides to create an experiment that will test whether this question is true. His hypothesis is that a fly will not live without calcium in its diet. Dr. Alexander believes that flies must have calcium in their diet. In one of Dr. Alexander’s experiments, he feeds one hundred flies a normal diet with calcium. Then he feeds one hundred more flies a diet without calcium. Over seven days he records the following data:

Fed Calcium Not Fed Calcium
Flies alive before test 100 100
Flies alive after test 92 10

Based off the data above what would be a valid conclusion Dr. Alexander could make?

Calcium is an essential part of a fly's diet.

The experiment did not provide definite results.

Calcium is a nonessential part of a fly’s diet.

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]
