Final Answer:
To cover a distance of 1mm, approximately 1,000 prokaryotic cells need to be arranged side by side.
Step-by-step explanation:
The average size of a prokaryotic cell, such as a bacterium, is around 1 to 5 micrometers (µm).
To find the number of cells needed to cover 1mm, we can convert the size from micrometers to millimeters. Since 1 millimeter is equal to 1,000 micrometers, an average bacterium is about 0.001 to 0.005 millimeters in size.
To cover 1mm, we can estimate that approximately 1,000 (1mm / 0.001mm) prokaryotic cells would need to be arranged side by side.
This calculation assumes a simplified scenario where cells are packed tightly without any gaps between them.
