The map includes 83 â or nearly 4 percent â of the 2,106 mosques in the United States as of 2010. Mosques from Clarion Projectâs list were excluded if TheDCNF could not verify their addresses. These include Islamist communes like Islamberg in New York. Several mosques on the Clarion Projectâs list stand out. Dar al-Hijrah, located just outside Washington in Falls Chruch, Virginia, for example, was the place of worship for two of the 9/11 hijakers.
Platelets are derived from bone marrow cells called megakaryocytes. Megakaryocytes are huge cells that break into fragments to form platelets. These cell fragments have no nucleus but do contain structures called granules.
Of these, the platelets are the smallest. They are produced by the remains of the larger cells known as megakaryocytes. The megakaryocytes are found in the red bone marrow. This is in fact the reason why blood cells are considered formed elements instead of cells.
