Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.itochondria are unusual organelles.

U.S. immigration law is very complex, and there is much confusion as to how it works. The Immigration and Naturalization Act (INA), the body of law governing current immigration policy, provides for an annual worldwide limit of 675,000 permanent immigrants, with certain exceptions for close family members.
From 1996 to 1998, the number of immigrants in detention increased from 8,500 to 16,000 and by 2008 this number increased to more than 30,000. According to the Global Detention Project, the United States possesses the largest immigration detention system in the world. In 2003, the U.S. Immigration and Customs Enforcement agency (ICE) was created under the Department of Homeland Security. ICE enforces the United Statesâ immigration and customs laws, uses investigative techniques to apprehend and detain those suspected of violating them, and then deports many of these individuals.
