QUES: Rapid environmental changes typically cause mass extinctions. More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).

QUES: It is widely agreed that the mallard (Anas platyrhynchos) is the ancestor of all breeds of domestic duck (with the exception of the Muscovy duck (Cairina moschata), which is not closely related to other ducks). Ducks are farmed mainly for their meat, eggs, and down. As is the case with chickens, various breeds have been developed, selected for egg-laying ability, fast growth, and a well-covered carcase. The most common commercial breed in the United Kingdom and the United States is the Pekin duck, which can lay 200 eggs a year and can reach a weight of 3.5 kg (7.7 lb) in 44 days. In the Western world, ducks are not as popular as chickens, because the latter produce larger quantities of white, lean meat and are easier to keep intensively, making the price of chicken meat lower than that of duck meat. While popular in haute cuisine, duck appears less frequently in the mass-market food industry. However, things are different in the East. Ducks are more popular there than chickens and are mostly still herded in the traditional way and selected for their ability to find sufficient food in harvested rice fields and other wet environments.

QUES: In 1928, Nasser went to Alexandria to live with his maternal grandfather and attend the city's Attarin elementary school. He left in 1929 for a private boarding school in Helwan, and later returned to Alexandria to enter the Ras el-Tin secondary school and to join his father, who was working for the city's postal service. It was in Alexandria that Nasser became involved in political activism. After witnessing clashes between protesters and police in Manshia Square, he joined the demonstration without being aware of its purpose. The protest, organized by the ultranationalist Young Egypt Society, called for the end of colonialism in Egypt in the wake of the 1923 Egyptian constitution's annulment by Prime Minister Isma'il Sidqi. Nasser was arrested and detained for a night before his father bailed him out.
