Our own currency tells a lot about the United States, its history, and the values it holds dear. The one-cent penny, for example, shows the head of Abraham Lincoln, president during the U. S. Civil War, on one side and the monument erected to him in Washington, DC, on the other. The 25-cent quarter features George Washington, the first president, and one U. S. symbol, the bald eagle. The back of the ten-cent dime shows a torch, olive and oak branches, and the Latin words “E Pluribus Unum” (“out of many, one”). These are symbols for liberty, peace, and strength—three core U. S. values—and one of the nation’s traditional mottoes.

What is the main structural difference between enveloped and nonenveloped viruses? a) enveloped viruses have their genetic material enclosed by a layer made only of protein.b) nonenveloped viruses have only a phospholipid membrane, while enveloped viruses have two membranes, the other one being a protein capsid.c) enveloped viruses have a phospholipid membrane outside their capsid, whereas nonenveloped viruses do not have a phospholipid membrane.d) both types of viruses have a capsid and phospholipid membrane; but in the nonenveloped virus the genetic material is between these two membranes, while in the enveloped virus the genetic material is inside both membranes.
