Which among the three principles of the cell theory can be practically applied in healthcare by promoting the use of sterilization and disinfection Why do you think so?
One element of the cell theory which is practical applications in healthcare is all cells come from pre existing cells. Yeah because it promotes the use of sterilization and disinfection. We know that all cells come from pre existing cells created through the process of cell division.
