Final answer:
The average duration for cell division can vary greatly depending on the cell type and conditions, ranging from a few hours to several days.1) Days
Step-by-step explanation:
The average duration for cell division can vary depending on the cell type and conditions. In humans, the cell turnover can range from a few hours in early embryonic development to an average of two to five days for epithelial cells. Some specialized cells, such as cortical neurons or cardiac muscle cells, spend their entire lifetime without dividing. Therefore, there is no specific average duration for cell division that applies universally.
