Bacterial Cells. Bacterial cells are very small-about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). Common Escherichia coli, or E.coli, bacteria are rod-shaped bacteria, 1 micron by 2 microns long.
1 Installing a concrete paver patio averages between $8 and $15 per square foot.  Stone: The most natural option, stone comes in several sizes, textures, colors and styles. Most homeowners opt for stone to create a design-focused patio. Installing a stone paver patio averages between $4 and $8 per square foot.
The options are really endless given a good budget but even on a tight budget there are many possibilities. I researched the average cost of a simple patio and it turns out that on the low end a simple concrete pave patio can be installed for around $2000. A covered patio complete with over head fan will likely cost $5000 to $7000. Those prices seem quite low considering you are adding âlivableâ so-to-speak, areas to your property but most homeowners are looking for something more substantial with unique design and function.
