QUES: Most annelids have a pair of coelomata (body cavities) in each segment, separated from other segments by septa and from each other by vertical mesenteries. Each septum forms a sandwich with connective tissue in the middle and mesothelium (membrane that serves as a lining) from the preceding and following segments on either side. Each mesentery is similar except that the mesothelium is the lining of each of the pair of coelomata, and the blood vessels and, in polychaetes, the main nerve cords are embedded in it. The mesothelium is made of modified epitheliomuscular cells; in other words, their bodies form part of the epithelium but their bases extend to form muscle fibers in the body wall. The mesothelium may also form radial and circular muscles on the septa, and circular muscles around the blood vessels and gut. Parts of the mesothelium, especially on the outside of the gut, may also form chloragogen cells that perform similar functions to the livers of vertebrates: producing and storing glycogen and fat; producing the oxygen-carrier hemoglobin; breaking down proteins; and turning nitrogenous waste products into ammonia and urea to be excreted.

QUES: Rates of interreligious marriage vary widely: In the United States, it is just under 50%, in the United Kingdom, around 53%; in France; around 30%, and in Australia and Mexico, as low as 10%. In the United States, only about a third of children from intermarriages affiliate with Jewish religious practice. The result is that most countries in the Diaspora have steady or slightly declining religiously Jewish populations as Jews continue to assimilate into the countries in which they live.[citation needed]

ANS: as low as 10%
QUES: Most of Bermuda's black population trace some of their ancestry to Native Americans, although awareness of this is largely limited to St David's Islanders and most who have such ancestry are unaware of it. During the colonial period, hundreds of Native Americans were shipped to Bermuda. The best-known examples were the Algonquian peoples who were exiled from the southern New England colonies and sold into slavery in the 17th century, notably in the aftermaths of the Pequot and King Philip's wars.
