1. A single bacterium is placed in a bottle full of nutrients at 11 A.M. The number of bacteria doubles every minute. At 12 noon the bottle is full of bacteria. a) How full do you think the bottle will be before the bacteria "realize" (or would, if they were human!) that they "have a problem"? 11.59am b) At what time will the bottle be half full of bacteria? 2. What is the current world population size for humans? 3. Given present birth and death rates, what is the doubling time in years for the human population? 4. At the current rate of growth, the earth's population would double in what year? 5. How many children do you think each couple would need to have for the world's population to stay the same? 6. How many children do you think each couple would need to have for the world's population to decrease?
