What is the viral envelope, and what does the presence (or absence) of it tell you about the type of virus? The viral envelope surrounds the viral capsid and serves as an additional barrier to the external environment. The majority of animal viruses are enveloped where as plant or bacteria infecting viruses are not. You go to visit a friend who has chickenpox. While visiting what are 2 things you will be sure to avoid so that you don't also become infected? You should keep a distance esp...
