Answer:
Hello, Besides the intracellular movement of organelles, the cytoskeleton is responsible for chromosome movement during cell division and for cytokinesis. This intricate network of protein filaments, which runs throughout cytoplasm, makes up a dynamic, continuously reorganizing framework, not a static scaffolding.
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell's parts. In addition, they provide a basis for movement and cell division. Hope That Helps!

Their thick fur and layer of fat help to insulate them against the extreme cold temperatures of their habitat.
