PETROLEUM (पेट्रोलियम) Petrol At some places in nature, a thick, viscous and dark colored liquid is found under the rock, which mainly contains aliphatic hydrocarbons up to C 1 to C 40 , this fluid is called refined oil or petroleum. The word petroleum is derived from the Latin words petra and olium which is found under rocks within the earth, hence it is also called mineral oil. Within the earth, this fluid floats above the salt solution. A gas atmosphere exists along with the floating petroleum inside the Earth, which is called natural gas. Petroleum is also called liquid gold. In the present era, this fluid is more valuable than gold for any nation. The progress of any nation depends to a large extent on how much petroleum it has. Its use is very important in various tasks like agricultural industry, traffic communication etc. This oil is found in the highest amount in the United States. Russia Venezuela is also found in greater quantities in Mexico, Burma etc. ...

Biodiversity
Rainforest biodiversity is a term created by coincidence of life and diversity, which usually refers to the diversity and variability of life on Earth. According to the United Nations Environment Program (UNEP), biodiversity biodiversity typically measures the level of diversity of genetic, species, and ecosystem. Biodiversity signifies the health of any biological system. Life on Earth is present in millions of unique biological species. In 2010, the International Year of Biodiversity, has been declared.
Cellular circulation
Hybrid cells are obtained from the reconstruction of somatic cell compounding physiological cells. Generates normal human filament cells or white blood cells with the mouse continuous cell lines. For cell computation, ultraviolet rays use Sandai virus or polyethylene glycol. In the hybrid cell, there are two nuclei initially, which are later fused. Thus, the production of hybrid cells is called the somatic cell hybridization.

The cultivation of coffee is related to the production of food and other goods through agricultural farming and forestry. Agriculture was a major development, which led to the rise of civilizations, in which pet was followed and plants (crops) were grown, thereby producing additional food. It enabled the development of a more densely populated and stratified society. The study of agriculture is known as agricultural science and related topics related to Horticulture are studied in Horticulture.Many varieties of techniques and characteristics come under agriculture, in which the appropriate land is expanded to grow the plants, water channels are dug and other forms of irrigation are used. Growing of crops on arable land and feeding livestock on pasture and rangeland by graziers has been mainly related to agriculture. Identifying the different forms of agriculture and their quantitative growth became the main issues of thought in the last century. In the developed world, this region extends from organic farming (eg, permaculture or organic farming) to intensive agriculture (eg industrial agriculture). Modern agronomy, hybridization in plants, pesticides and fertilizers and technological improvements have increased the production of crops by speeding up, and it has also become a cause of ecological damage widely and has adversely affected human health. Modern practices of selective reproduction and animal husbandry practices such as intense pig farming (and similar practices are also applied on hen) have increased the production of meat, but by increasing the health effects of animal cruelty, antibiotic drugs In industrial production of hormones and meat, issues have arisen in general about the chemicals used in the work.
There is also a range of decorative or foreign products. Since 2000 the plants are being used in the production of biological fuels, biopharmaceuticals, bioplastics, and pharmaceuticals. Special food items include cereals, vegetables, fruits and meat. Fibers include cotton, wool, sun, silk and flax. Raw materials include wood and bamboo. The stimulants include tobacco, alcohol, opium, cocaine and digitalis. Other useful substances are also produced from plants, such as resins. Bio-fuels include methane, biomass (biomass), ethanol and biodiesel. Cut flowers, nursery plants, tropical fish and pet birds for business are some decorative products. In 2007, nearly one-third of the world's workers were employed in the agricultural sector. However, since the beginning of industrialization, the importance of agriculture has diminished and in 2003 - for the first time in history-service sector overtook agriculture as an economic sector because it provided jobs to the maximum number of people worldwide. Despite the fact that agriculture provides employment to more than a third of the population of the world, agricultural production accounts for less than five percent of the gross world product (a set of gross domestic product). .
