Explanation:

The euro offers many benefits for individuals, businesses and the economies of the countries that use it.

The European Union (EU) membership is generally more beneficial for the member countries.

The European Union is an organization of 27 member states that came into existence after the Maastricht Treaty on November 1, 1993. Its main focus was economic interaction and development among European countries and the promotion of peace and democratic ideals.

Thus, membership in the EU is a strong point for the members as they benefit from the single currency, the Euro, which provides stiff competition to the value of the dollar. Member states also collaborate in military, environmental, ideological, and academic areas. The porous borders of member states are a plus point for tourists and businesses.

The lack of investment, technology and infrastructure, as well as the presence of bureaucratic inefficiencies, have all contributed to the decline of the country’s industrial sector.

One of the major causes of the decline of Indian industry has been the lack of government investment in the sector. The Indian government has failed to provide adequate resources and support for the development of the industrial sector, leading to an overall lack of growth. In addition, the country’s economic policies have favored the agricultural sector over the industrial sector and this has caused the industrial sector to suffer.

Another major cause of the decline of Indian industry has been the low levels of technology and infrastructure.

Workers in Taung, South Africa, found the type specimen for Australopithecus, the first specimen, in a lime quarry in 1924. The specimen was examined by Australian anatomist Raymond Dart, who at the time was employed by Johannesburg's University of the Witwatersrand. He called Australopithecus africanus, a three-year-old upright primate whose fossilised skull was found. In February 1925, Nature published the initial account. Dart got to the opinion that the fossil represented an early human progenitor when he noticed that it had some anthropomorphic characteristics.

The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondrial (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the food's energy into the a form that can be utilised by cells.

Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors can also cause DNA to change. These external agents of genetic change are called mutagens.

A mutagen is a physical or chemical substance that, in genetics, irreversibly alters genetic material, often DNA, in an organism. This raises the frequency of mutations over the background level of spontaneous mutations. Such mutagens may be carcinogenic since numerous mutations in animals can result in cancer, albeit not necessarily all of them are. While certain compounds turn become mutagenic substances through biological mechanisms, all mutagens have distinctive mutational fingerprints.

Mutagenesis is the term for the modification of DNA. Not all mutations are brought on by mutagens: "spontaneous mutations" result from mistakes in DNA replication, repair, and recombination, as well as spontaneous hydrolysis.

A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both. A polygonal circuit's segments are referred to as its edges or sides.

CD = BC = 28

FD = 1/2 (BD) = 1/2 (3) = 16

The combination of nutrients rich loess and water flowing makes the North China Plain so fertile.

The main reason loess soils are one of the most fruitful in the world is the presence of silt particles, which assures a good supply of water that is available to plants, strong soil aeration, extensive root penetration, and ease of cultivation and seedbed generation. It drains water quite effectively and is rich in minerals. It is simple to break up or till for seeding.

Typically, loess erodes quite slowly. For over a thousand years, Chinese farmers have been cultivating the loess near the Yellow River. World Bank and Chinese government support helped repair 4 million hectares of land in the Loess Plateau, more than tripling local farmers' wages, reducing erosion, lowering the risk of flooding, and sharply improving grain production.

Babur's accession to the throne in 1526 marked the beginning of the Great Mughal era, which lasted until Aurangzeb's demise in 1707. An era in Indian history came to an end with the passing of Aurangzeb. The Mughal empire was the biggest in India at the time of Aurangzeb's passing. However, the Mughal Empire collapsed around fifty years after his passing.

The following factors contributed to the Mughal empire's downfall in India:

Wars over succession: Unlike the law of primogeniture, the Mughals did not adhere to any laws governing succession. As a result, a war of succession between the brothers for the throne began every time a ruler passed away.

Policies of Aurangzeb: Aurangzeb was unaware that the enormous Mughal Empire depended on the people's willing support.

The stability of the Mughal empire was harmed by Aurangzeb's strict religious beliefs and his treatment of Hindus. The Rajputs, who had made significant contributions to the power of the Empire, abandoned him.

The successors to Aurangzeb were weak, and as a result, they fell prey to the plots and intrigues of the nobles' divided factions.

Shah Jahan's enthusiasm for building had left the treasury empty.
