The paper considers a characteristically loaded equation of a mixed hyperbolic-parabolic type with degeneration of order in the hyperbolicity part of the domain. In the hyperbolic part of the domain. we have a loaded one-velocity transport equation. known in mathematical biology as the Mac Kendrick Von Forester equation. https://www.roneverhart.com/Nerds-Laffy-Taffy-SweeTarts-Trolli-Halloween-Candy-Assortment-50-Piece-Bag/
