What would happen to the mice in Frederick Griffith s transformation experiments if he mixed live S strain and heat killed R strain and inoculated this mixture into the mice Answer

Each sketch below shows a flask with some gas and a pool of mercury in it The gas is at a pressure of 2 atm A J shaped tube is connected to the bottom of the flask and the mercury can freely flow in or out of this tube You can assume that there is so much more mercury in the pool than can fit into the tube that even if the J tube is completely filled the level of mercury in the pool won t change Notice also that in the left sketch the J tube is open at its other end so that air from the atmosphere can freely flow On the other hand in the right sketch the J tube is closed at its other end and you should assume there is no gas between the mercury and the closed end of the tube To answer this question you must decide what the mercury level will be when the mercury finally stops flowing in or out of the tube By moving the sliders back and forth you ll see different levels of mercury in the J tube Select the final correct level for each sketch open tube 2 0 atm 12 3 0 2 5 2 0 1 5 m 1 0 0 5 0 0 J 6 closed tube 2 0 at 3 4 3 0 2 5 20 1 5 m ELLE 1 0 010 C 0 5 0 0 5
