QUES: Throughout its history, the city has been a major port of entry for immigrants into the United States; more than 12 million European immigrants were received at Ellis Island between 1892 and 1924. The term "melting pot" was first coined to describe densely populated immigrant neighborhoods on the Lower East Side. By 1900, Germans constituted the largest immigrant group, followed by the Irish, Jews, and Italians. In 1940, whites represented 92% of the city's population.
In the year 1942, what percentage of white Americans made up New York City?

ANS: 92

QUES: The Czech people gained widespread national pride during the mid-eighteenth century, inspired by the Age of Enlightenment a half-century earlier. Czech historians began to emphasize their people's accomplishments from the fifteenth through the seventeenth centuries, rebelling against the Counter-Reformation (which had denigrated Czech and other non-Latin languages). Czech philologists studied sixteenth-century texts, advocating the return of the language to high culture. This period is known as the Czech National Revival (or Renascence).
What did Czech philologists advocate?

ANS: the return of the language to high culture

QUES: Virgil's biographical tradition is thought to depend on a lost biography by Varius, Virgil's editor, which was incorporated into the biography by Suetonius and the commentaries of Servius and Donatus, the two great commentators on Virgil's poetry. Although the commentaries no doubt record much factual information about Virgil, some of their evidence can be shown to rely on inferences made from his poetry and allegorizing; thus, Virgil's biographical tradition remains problematic.
Whose two commentaries were incorporated into Virgil's biography by Suetonius?

ANS: Servius and Donatus

QUES: Cytokinins are a class of plant hormones named for their control of cell division or cytokinesis. The natural cytokinin zeatin was discovered in corn, Zea mays, and is a derivative of the purine adenine. Zeatin is produced in roots and transported to shoots in the xylem where it promotes cell division, bud development, and the greening of chloroplasts. The gibberelins, such as Gibberelic acid are diterpenes synthesised from acetyl CoA via the mevalonate pathway. They are involved in the promotion of germination and dormancy-breaking in seeds, in regulation of plant height by controlling stem elongation and the control of flowering. Abscisic acid (ABA) occurs in all land plants except liverworts, and is synthesised from carotenoids in the chloroplasts and other plastids. It inhibits cell division, promotes seed maturation, and dormancy, and promotes stomatal closure. It was so named because it was originally thought to control abscission. Ethylene is a gaseous hormone that is produced in all higher plant tissues from methionine. It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.
What acid slows or stops cell division?

ANS:
Abscisic
