Assignment 2: Dynamics of Population Growth Full Name: Chien Chiu Hsiung Lab Section: WZ2A Last four digits of your SSN: 6917 Lab instructor name: Professor G. Perrin ( http://www.brooklyn.cuny.edu/bc/ahp/Lab/Lab.html , select the lab Population Growth ) Hints on graphing: It is crucial to your grade that you properly label your graphs (x and y axis will not be counted as labels). The x and y axis must be in even increments, ex: 10,20,30 or 225, 325, 425, it can be any increment as long as it’s constant throughout the axis. They do not have to be the same increment for x and y. Part 1 (read all six pages): Exponential Growth Fill in chart below and plot a graph of the results . (1 point ) Initial Population: __1 _ Growth Rate: __.5 _ Time: __10 Time # of bacteria 1 2 2 3 3 4 4 7 5 12 6 20 7 33 8 55 9 90 10 148 1. Why do the numbers of bacteria increase slowly at first then more rapidly later ( 0.5 pt )? The numbers of bacteria increase slowly at first then more rapidly later because of exponential growth which created a J-shaped curve. From 1-5 hours, the bacteria does not seem to be
