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?

101. A 24-year-old woman comes to the physician because of a 2-day history of fever, cramping lower abdominal pain, and diarrhea with frequent, small bowel movements mixed with blood and mucus. Two children who attend the day-care center where this patient works have similar symptoms. Her temperature is 38°C (100.4°F). Physical examination shows no other abnormalities. Culture of the stool grows nonlactose- fermenting, gram-negative bacilli. Which of the following is the most likely mechanism of the pathogenesis of this infection? A) Antigen-antibody complexes B) Immune response to cross-reactive antigens C) Invasion of colonic mucosa D) Multiplication in the Peyer's patches E) Toxin binding to small intestinal mucosa
