Question

Quizplus · Accepted Answer

The term "dynamic" refers to something that is constantly changing or in motion. In the context of cell biology and the cytoskeleton, all three types of filaments (microtubules, intermediate filaments, and actin filaments) are considered dynamic because they can grow, shrink, bend, and move in response to various cellular signals and needs. Therefore, the best choice is C) ever-changing in structure.
