Approximately how much bigger is a red blood cell than an E. coli cell
Homework Answers
The size of Escherichia coli (E.coli) vary from 0.5 microns to 2 micrometer.
On an average it is 
m. ( 0.5 + 2/2 =
2.5/2 = 1.25 m )
The size of Red blood cell (RBC) vary from 6 microns to 9 micrometer.
On an average it is 7.5 m (6+9/2 = 15/2 =
7.5 m)
So, Size of RBC /Size of E.Coli = 7.5 m/1.25 m = 6
So, approximately RBC is 6 times larger than the Escherichia coli cell.

The average red blood cell count in young women is assumed to be approximately 4.5 million red cells per cubic milliliter of blood. Red cell counts taken on a randomly drawn sample of 12 women athletes yield the data given below. 5.2, 4.7, 4.3, 5.5, 4.5, 4.5, 5.5, 4.5, 5.3, 4.7, 5.1, 4.8 (sample data: red cell counts per cubic ml (in millions)) Based on this data, do women athletes appear to have higher red cell counts than the population...

A model of a red blood cell portrays the cell as a spherical capacitor, a positively charged liquid sphere of surface area A separated from the surrounding negatively charged fluid by a membrane of thickness t. Tiny electrodes introduced into the interior of the cell show a potential difference of 100 mV across the membrane. The membrane's thickness is estimated to be 95 nm and has a dielectric constant of 5.00 (a) If an average red blood cell has a...

A red blood cell typically carries an excess charge of about –2.5 × 10–12 C distributed uniformly over its surface. The red blood cells can be modeled as spheres approximately 7.0 μm in diameter and with a mass of 9.0 × 10–14 kg. How many excess electrons does a typical red blood cell have? Does the mass of the extra electrons appreciably affect the mass of the cell? To find out, calculate the ratio of the mass of the extra...
