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.
Dogs have an additional organ in their nasal cavity known as Jacobson's organ. This organ's function can best be described as a combination of taste and smell. Dogs can literally taste the air. A dog that is experiencing this taste/smell experience usually holds his mouth in a semi-open position that resembles a grin.
