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.
true STANDARD HEMATOLOGY: Platelets, or thrombocytes, are small, colorless, enucleated bodies. They are produced in the bone marrow by fragmentation of megakaryocytes. Megakar â¦ yocytes are large cells found in bone marrow that produce platelets by fragmenting their cytoplasm. Platelets play a vital role in the hemostatic process, which prevents blood loss. When the endothelial lining of a blood vessel is traumatized, platelets are stimulated to go to the site of injury, where they form a plug that helps reduce blood loss.
