Answers
Answer:
down
Explanation:
Ans 1.This system has three main components: the heart, the blood vessel and the blood itself.
Ans 2. The four basic ABO phenotypes are O, A, B, and AB. After it was found that blood group A RBCs reacted differently to a particular antibody (later called anti-A1), the blood group was divided into two phenotypes, A1 and A2. RBCs with the A1 phenotype react with anti-A1 and make up about 80% of blood type A.
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.[1] Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container; i. e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. Three dimensional mathematical shapes are also assigned volumes. Volumes of some simple shapes, such as regular, straight-edged, and circular shapes can be easily calculated using arithmetic formulas. Volumes of complicated shapes can be calculated with integral calculus if a formula exists for the shape's boundary. One-dimensional figures (such as lines) and two-dimensional shapes (such as squares) are assigned zero volume in the three-dimensional space.Seoul, Korean Sŏul, formally Sŏul-t’ŭkpyŏlsi (“Special City of Seoul”), city and capital of South Korea (the Republic of Korea). It is located on the Han River (Han-gang) in the northwestern part of the country, with the city centre some 37 miles (60 km) inland from the Yellow Sea (west). Seoul is the cultural, economic, and political centre of South Korea.The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century, Korea was ruled by the Goryeo dynasty (918–1392) and the Joseon dynasty (1392–1897). The succeeding Korean Empire was annexed into the Empire of Japan in 1910. After World War II, Korea was divided into Soviet and U.S.-administered zones, with the latter becoming the Republic of Korea in August 1948. In 1950, a North Korean invasion began the Korean War and after its end in 1953, the country's economy began to soar, recording the fastest rise in average GDP per capita in the world between 1980 and 1990. The June Struggle led to the end of authoritarian rule in 1987 and the country is now considered among the most advanced democracies in Asia, with the highest level of press freedom. However, corruption and political scandals remains a serious problem, with half of all living former South Korean presidents currently in prison for various crimes ranging from abuse of authority, bribery and embezzlement.[10][11][12]
South Korea is a highly developed country, ranking as the third-highest country on the Human Development Index in Asia. It is a member of the OECD's Development Assistance Committee, the G20 and the Paris Club. Its economy ranks as the world's tenth-largest by nominal GDP. Its citizens enjoy one of the world's fastest Internet connection speeds. The country is the world's fifth-largest exporter and eighth-largest importer. South Korea was in 2017 the world's 7th largest emitter of carbon emissions and the 5th largest emitter per capita. Since the 21st century, South Korea has been renowned for its influential pop culture, particularly in music (K-pop), TV dramas and cinema, a phenomenon referred to as the Korean Wave.
