Question

Axon diameters of cortico-cortical fibers in the human brain range from 0.16 μm to 9 μm in length. Convert the length, 0.16 μm, into meters using scientific notation. (Use the following format: a x 10^b using the correct number of significant figures).

A. 1.6 x 10^(-7)
B. 1.6 x 10^(-6)
C. 1.6 x 10^(-5)
D. 1.6 x 10^(-8)

Answer 1

The length of 0.16 μm converted into meters using scientific notation is 1.6 x 10⁻⁷ m. So, the correct answer is A.

Step-by-step explanation:

It looks like there's a slight misunderstanding in the provided explanation. Let's go through the calculation again:

Starting with the given value:
`\(0.16 \, \mu m\)`

To convert from micrometers
`(\(\mu m\))` to meters
`(\(m\))`, we use the conversion factor
`\(1 \, \mu m = 1 * 10^(-6) \, m\).`

`\[ 0.16 \, \mu m = 0.16 * 10^(-6) \, m \]`

The given explanation mentions expressing
`\(0.16\) as \(1.6 * 10^(-1)\)`, but this introduces an error because it changes the original value.

So, the correct calculation is:

`\[ 0.16 * 10^(-6) \, m \]`

The correct scientific notation, without introducing an extra step of expressing
`\(0.16\) as \(1.6 * 10^(-1)\)`, is:

`\[ 1.6 * 10^(-7) \, m \]`

Therefore, the correct answer is **A. 1.6 x 10⁺⁷ m**.
