Question

Suppose that you have some rod-shaped bacteria, and each bacterium is 3 micrometers long. If the bacteria were arranged end to end in chains, how many would it take to form a chain that is 6 centimeters long?

Answer 1

Number of bacteria required
`= 20000`

Step-by-step explanation:

Given -

Size of each bacterium
`= 3` micrometers long

These bacteria are arranged end to end.

The size of chain to be formed is equal to
`6` centimetres

Let us say that in forming a chain of
`6` centimetres nearly X number of individual bacterium are required.

hence, number of bacterium required to form
`6` centimetres chain can be represented as

`X = (6 * 10000)/(3) \\X = 20000`

Number of bacteria required
`= 20000`
