QUES: Life expectancy at birth is estimated to be 52.2 years in 2012 among the lowest in the world. The AIDS epidemic is a large problem in Namibia. Though its rate of infection is substantially lower than that of its eastern neighbour, Botswana, approximately 13.1% of the adult population is[update] infected with HIV. In 2001, there were an estimated 210,000 people living with HIV/AIDS, and the estimated death toll in 2003 was 16,000. According to the 2011 UNAIDS Report, the epidemic in Namibia "appears to be leveling off." As the HIV/AIDS epidemic has reduced the working-aged population, the number of orphans has increased. It falls to the government to provide education, food, shelter and clothing for these orphans.
How many orphans are there in Namibia?

ANS: unanswerable

QUES: The abdomen is the largest tagma of the insect, which typically consists of 1112 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum and sternum. Terga are separated from each other and from the adjacent sterna or pleura by membranes. Spiracles are located in the pleural area. Variation of this ground plan includes the fusion of terga or terga and sterna to form continuous dorsal or ventral shields or a conical tube. Some insects bear a sclerite in the pleural area called a laterotergite. Ventral sclerites are sometimes called laterosternites. During the embryonic stage of many insects and the postembryonic stage of primitive insects, 11 abdominal segments are present. In modern insects there is a tendency toward reduction in the number of the abdominal segments, but the primitive number of 11 is maintained during embryogenesis. Variation in abdominal segment number is considerable. If the Apterygota are considered to be indicative of the ground plan for pterygotes, confusion reigns: adult Protura have 12 segments, Collembola have 6. The orthopteran family Acrididae has 11 segments, and a fossil specimen of Zoraptera has a 10-segmented abdomen.
How many segments make up an insects abdomen?

ANS: 1112 segments

QUES: Evidence exists that native peoples traveled through Oklahoma as early as the last ice age. Ancestors of the Wichita and Caddo lived in what is now Oklahoma. The Panhandle culture peoples were precontact residents of the panhandle region. The westernmost center of the Mississippian culture was Spiro Mounds, in what is now Spiro, Oklahoma, which flourished between AD 850 and 1450. Spaniard Francisco Vasquez de Coronado traveled through the state in 1541, but French explorers claimed the area in the 1700s and it remained under French rule until 1803, when all the French territory west of the Mississippi River was purchased by the United States in the Louisiana Purchase.
When did France sell Oklahoma's land to the US?

ANS: 1803

QUES: Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids. The digestive enzymes however are mostly secreted as their inactive precursors, the zymogens. For example, trypsin is secreted by pancreas in the form of trypsinogen, which is activated in the duodenum by enterokinase to form trypsin. Trypsin then cleaves proteins to smaller polypeptides.
Where does protein digestion occur?

ANS:
in the stomach and duodenum
