WebExample 2: Find the number of bacteria in a culture . A culture contains 10,000 bacteria initially. After an hour, the bacteria . count is 25,000. (a) Find the doubling period. (b) Find the number of bacteria after 3 hours. Solution (a): We need to find the function that models the population growth, n(t). In WebThe exponential or log phase of growth is marked by predictable doublings of the population, where 1 cell become 2 cells, becomes 4, becomes 8 etc. Conditions that are optimal for the cells will result in very rapid growth … georgetown playfield seattle wa
