Bacteria grown in a lab experience what is called an 'exponential phase' of population growth. Suppose that, during this phase, a colony of Mycobacterium tuberculosis you are growing has a per capita growth rate, r, of 0.063 per hour. If the size of your colony at the start of the exponential phase is 0.25 billion cells, then approximately how large will it be in 48 hours? ?? billion cells

Population Growth

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.
