Which of the following provides strong evidence for the endosymbiotic hypothesis?
chloroplast genes are more similar (& closely related) to mitochondrial genes than to bacterial genes bacterial genes are more similar (& closely related) to mitochondrial genes than to chloroplast genes
nuclear genes are more similar (& closely related) to cyanobacterial genes than to genes from archaea
mitochondrial genes are more similar (& closely related) to bacterial genes than to nuclear genes of the host
chloroplast genes are more similar (& closely related) to nuclear genes of the host than to mitochondrial genes

The correct option is Mitochondrial genes are more similar (& closely related) to bacterial genes than to nuclear genes of the host.

Explanation:

The endosymbiotic hypothesis explains the fact that prokaryotes might have given birth to eukaryotes. The hypothesis states that organelles such as mitochondria and chloroplast once existed as prokaryotic organisms. These smaller prokaryotes were engulfed by bigger prokaryotes and hence eukaryotes came into existence.

This hypothesis can be supported by the evidence that the mitochondria and chloroplast are more like the bacterial cells rather than the host nucleus in which they are present. They have their own DNA like a bacterial cell and machinery to transcribe this DNA just like a bacterial cell.These organelles are enclosed by membranes just like a bacterial cell.

the answer will be a) proteins i believe

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]
