The clearance angle on a rotary microtome is?

Explanation:
The clearance angle is the small tilt between the knife edge and the surface of the block that creates a tiny gap so the blade can shear the tissue rather than rub against the paraffin as it cuts. On a rotary microtome, this clearance is kept in a narrow range, typically about 3 to 8 degrees. That slight offset allows smooth, clean cuts by reducing friction and preventing the blade from scraping the block while still keeping the edge close enough to the block to slice effectively. If the angle is too small, the blade may rub and cause chatter or compression; if it’s too large, cutting efficiency drops and the blade wears more quickly, potentially distorting sections. So the standard range of 3–8 degrees is why this option is the best choice.
