Which of the following statements is correct regarding the human x chromosomes?

It is present in every somatic cell of male and female.

Further Explanation:

The chromosomes are present in the nucleus of the cell. It consists of DNA material bounded to the protein molecule which is positively charged.

Twenty three pairs of chromosomes are present in every somatic cell of the human. Twenty two pair of chromosomes are referred to as autosomes while one pair of chromosomes is known as sex chromosome. The somatic cells are diploid in nature. Another type of cells are also present in the human body, they are known as gametic cell. These cells are haploid in nature as they have only twenty two chromosome and one sex chromosome.

In the human the sex chromosome denoted by “Y” is known to be responsible for determining the biological sex of the human. If XY chromosomes is present in the cell, it means it is the cells of male but if it is XX chromosome then this means they are male cell.

The karyotype of the human cell is develop by arranging the chromosomes in the decreasing order of their cell.

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]
