AAbout 3 to 4 nanometers
BAbout 25 to 30 nanometers
CAbout 40 to 50 nanometers
DAbout 8 to 10 nanometers
Answer & Solution
Correct answer: D. About 8 to 10 nanometers
1. The name intermediate comes from where these fibers sit on the width scale.
2. Their diameter is 8 to 10 nanometers.
3. That falls between the 7 nanometers of microfilaments and the 25 nanometers of microtubules.
4. The stated range is 8 to 10 nanometers.
