Chapter 6, Problem 11MC
Summary Introduction
Introduction:
A graph that represents the total number of microbes or organisms in a population over a period of time is called a growth curve. By using the arithmetic scale on the y-axis, an exponential growth plot causes some problems as it is difficult to determine and plot the actual number of cells at the beginning. To solve these problems a logarithmic (log) scale is used instead of arithmetic scale on the y-axis.

- Under ideal conditions, a population of bacteria can grow to more than 1036 in 24 hours. This is a statement of the populations: a. Density b. Carrying capacity c. Growth rate d. Biotic potentialarrow_forwardwhat is k and r for each condition? K (carrying capacity): can be estimated by finding the point where the growth curve levels off. Take the average of this data point and all data collected beyond this point to estimate k (note: if the bacteria population is still growing, you can just take the last value of data for k. r: choose any two points at the log phase of growth. Then use the r formula. Just choose two waste conditions for r and k calculation so I can get the idea of how to do this, thanks.arrow_forwardDescribe briefly:(a) Arithmetic growth(b) Geometric growth(c) Sigmoid growth curve(d) Absolute and relative growth ratesarrow_forward
