Summary Introduction

To complete: The table below to show how the bacterial population increases.

Introduction: Bacterium is a prokaryotic organism that copies their DNA and divide by binary fission. In binary division, a single cell becomes two cells, which then becomes four cells, eight cells, and so on.

Summary Introduction

To explain: The reason that the rate of increase changes over time and how the graph of data look.

Complete Table 1by doubling the number of bacteria (Clostridium sp.) and diatoms (Chaetoceros sp.) every 30 minutes and 60 minutes, respectively, and by writing the log10 of this number in the appropriate columns with the results , Draw a graph showing the growth (N) of the populations of both species from time = 0 (also written as t0) to time = 310 (t310) minutes. Draw both populations on the same graph. NB: It will be necessary to plot Chaetoceros sp. on a second y-axis. Label the axes and provide a suitable legends.
Fill in the Blanks Type your answers in all of the blanks and submit Consider two species of bacteria A and B with the same initial population. The species grow exponentially with growth rate rA = 0.05 for species A and rg = -0.025 for species B. Will the two species of bacteria ever have the same size? Type your answer here (Enter YES or NO) The time at which they reach the same size is t = Type your answer here (Enter -1000 if their size is never equal)
What is the generation time (in minutes) of a bacterial population that increases from 10,000 cells to 10,000,000 cells in fours hours of growth? Show computation.
