If the size of a bacteria is `1mu`, then how many bacteria will be there in a length of 1 m?

Options

A. `10^(3)`
B. `10^(-3)`
C. `10^(-6)`
D. `10^(6)`

Explanation

To solve the problem of how many bacteria of size 1 micrometer can fit in a length of 1 meter, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Size of Bacteria**:
The size of one bacterium is given as 1 micrometer (µm). We need to convert this measurement into meters for consistency with the length we are considering (1 meter).
\[ 1 \text{ micrometer} = 1 \times 10^{-6} \text{ meters} \]

2. **Determine the Length in Meters**:
We are considering a total length of 1 meter.

3. **Calculate the Number of Bacteria**:
To find out how many bacteria can fit into 1 meter, we divide the total length (1 meter) by the size of one bacterium (in meters).
\[ \text{Number of bacteria} = \frac{\text{Total Length}}{\text{Size of one bacterium}} = \frac{1 \text{ meter}}{1 \times 10^{-6} \text{ meters}} \]

4. **Perform the Calculation**:
Now, we perform the division:
\[ \text{Number of bacteria} = \frac{1}{1 \times 10^{-6}} = 1 \times 10^{6} \]

5. **Conclusion**:
Therefore, the number of bacteria that can fit in a length of 1 meter is:
\[ \text{Number of bacteria} = 10^{6} \]

### Final Answer:
The number of bacteria that can fit in a length of 1 meter is \( 10^6 \).
