Movement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
Citizenship, Immigration and the Constitution. The 14th Amendmentâs Citizenship Clause is one of the Constitutionâs most important and underappreciated provisions. The clause grants full United States citizenship to anyone born on American soil (with a narrow exception for children of foreign diplomats) or naturalized by the federal government.
While the 13th Amendment to the United States Constitution outlawed slavery, it wasn't until three years later, in 1868, that the 14th Amendment guaranteed the rights of citizenship to all persons born or naturalized in the United States, including due process and equal protection of the laws.
