R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.

(inoculation is when the cells are first put
in the growth media)
A. Draw a log10 X vs. time graph and label the phases for batch cell growth.
B. Calculate the specific growth rate, μ, and mass doubling time, td, for the exponential growth phase.
C. Calculate kd, the specific rate of cell mass loss due to cell death
(For B & C, it will be helpful to re-plot the y-axis as In X or In (X/X.), and focus on only the data in that phase)
Using spreadsheet software will be helpful in drawing this graph and analyzing data for parts B & C. Be as quantitative as
possible, especially with the slopes of the growth and death phases. Use the inoculation time as time zero. You may
assume that kis zero during the exponential growth phase.
