The width of a human hair is about 17 micrometers. How many human erythrocytes could fit across the width of a hair? How many Ecoli bacteria could fit?

Respuesta :

Answer:

Two erythrocytes and 34 E.Coli Bacteria

Explanation:

Given -

Size of human hair i.e width of human hair is equal to [tex]17[/tex] micrometers

Size of an average erythrocytes or red blood cell is equal to 8 micrometers in diameter.

So the number of human erythrocytes could fit across the width of a hair is equal to

[tex]\frac{W_{Hh}}{D_{RBC}}[/tex]

Substituting the given values, we get -

[tex]\frac{17}{8} \\= 2[/tex]

Width of E.Coli bacteria is equal to [tex]0.5[/tex] micrometer

Number of E.Coli bacteria that could fit in with in the human hair is equal to

[tex]\frac{17}{0.5} \\= 34[/tex]
