The Java programming language also provides a do-while statement, which can be expressed as follows: The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top.
Vomeronasal organ. The vomeronasal organ (VNO), or the Jacobson's organ, is an auxiliary olfactory sense organ that is found in many animals. It lies close to the vomer and nasal bones. It was discovered by Frederik Ruysch prior to 1732 and later by Ludwig Jacobson in 1813. This organ is the sense organ involved in the flehmen response in mammals.
Recent research confirms Broom's suspicions about Jacobson's Organ. Signs of it appear, like portents, in the embryos of all higher land mammals, although in some, such as tree-living lizards, aquatic turtles and nearly all birds, it never actually materializes. There is no need for it.
