Assume you have inoculated a small number of bacterial cells into a supportive culture medium and incubated it while watching for an increase in numbers over time. you found that after a short period, the number of bacterial cells increased rapidly (exponentially). with time, growth slowed and eventually leveled off. how could you explain the leveling off with no additional increase in the bacterial number?

The growth ofbacteria is composed of diffferent phases like:
1.Lag phase:
In this phase bacteria become aware of the medium environment and prepare themselves for reproduction.
2. Exponential phase:
In this phase bacteria start dividing themsezlves in exponential form.
3. Stationary phase:
In this phase the growth of bacteria stop as a result of nutrient deficiency. 4. Decline phase: In this phase the growth of bacteria start to decrease due to deficiency of nutrients they start fighting with each other. Conclusion: It is cleared that bacterial growth become plane in stationary phase.

In my own word cell technology can  lead to advances in the understanding of diseases mechanism and transmission because diseases is very bad
