Alab technician places a colony of bacterial cells in a nutrient-rich growth medium. which event is the technician most likely to observe with a microscope?

When bacterial cells are placed in a nutrient rich medium containing all the nutrients required for the growth of the bacteria, the bacteria exhibit a typical growth curve. Initially on transferring into the medium, the population of bacteria remain the same for a short period called the lag phase. They increase in size and prepare the cells for cell division exhibiting active metabolism. The bacteria then enters the log phase, showing an increase in the number of bacteria in a logarithmic fashion by binary fission. Thus, the lab technician can observe the process of cell division by binary fission under the microscope. The bacterial cells then tend to remain constant in the stationary phase and finally decline in number due to the death of the cells.  

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
