Ans 1 A . The generation time for pseusdomonas is 40 minutes. And the culture is incubates for 4 hours or 240 minutes. Which makes 6 cycles so the number of generations will be 7.
B. If you have started with initial cells 2 ×103 , so after 4 hours the number of cells in the culture will be 1.28 × 105 cells
C. The culture cells can be plated and then CFU ( colony forming unit) counting can be done to know the number of cells. If the number match with the calculations , the latter is probably correct.
