You discover a new virus. It has a single stranded + sense RNA genome. It uses a special enzyme to convert the RNA genome into double stranded DNA. Transcription of mRNA is carried out from the DS DNA template. Which group in the Baltimore classification system would you place this virus into?

Group VI viruses (retroviruses)

Explanation:

Baltimore classified the viruses in different groups on the basis of their mode of replication and the type of genetic material they possess.

In the given question, the species which contains an ssRNA molecule but use DNA as an intermediate molecule to replicate is known as a retrovirus.

The retrovirus uses a special enzyme called reverse transcriptase which synthesizes the DNA from an RNA template. The DNA formed gets integrated into the host genome and gets replicated.

Thus, Group VI viruses are the correct answer.

answer; i believe the answer is (polygenic inheritance;

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]
