Cultures of the same species of diatom referred to in the previous question were treated with BDM,a reversible inhibitor of myosin function.Which of the following predictions is consistent with the hypothesis that an actin-myosin interaction is necessary for motility?

The hypothesis states that an actin-myosin interaction is necessary for motility. If BDM, a reversible inhibitor of myosin function, is added, it should decrease the motility of the cells in culture if the hypothesis is correct. Therefore, choice A is the best option. BDM inhibits myosin function, which is required for movement in diatoms. If myosin is not functioning correctly, movement is impacted, and this would decrease the motility of the cells in culture.
