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 even have a special scent detection system called Jacobsonâs organ or the vomeronasal organ. It is a sort of pancake-shaped pouch of special receptive cells that is located just above the roof of the mouth. It has ducts that open to both the mouth and the nose to allow scent molecules to enter it.
