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?

Two erythrocytes and 34 E.Coli Bacteria

Explanation:

Given -

Size of human hair i.e width of human hair is equal to 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

Substituting the given values, we get -

Width of E.Coli bacteria is equal to micrometer

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

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
