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.
In mammals and reptiles, pheromones may be detected by the vomeronasal organ, or Jacobson's organ, which lies between the nose and mouth, although some are detected by regular olfactory membranes. Terence McKenna proposed in his book Food of the Gods the controversial idea of exopheromones as chemical signals between, as opposed to among a single, species.
