Microfilaments Can Be Involved in Contractions That Change the Shape

Microfilaments can be involved in contractions that change the shape of a cell when they are

A) working with microtubules to bend cilia and flagella.
B) associated with motor proteins such as myosin.
C) complexed with intermediate filaments to form desmosomes.
D) being assembled from actin monomers.
E) associated with actin-associated proteins that are adding actin monomers to the "plus end" of the filament.
