A researcher tested Compound A on chemotaxing cells and measured the relative amount of filamentous actin found in the cells at different times. Based on the researcher’s observations on filamentous actin, what other observation regarding cell chemotaxis was MOST likely observed?   A. The cell moved toward the source of the signaling molecule only after the addition of Compound A.   B. The cell moved away from the source of the signaling molecule only after the addition of Compound A.   C. The cell first moved toward and then away from the signaling molecule after the addition of Compound A.   D. The cell did not move toward or away from the signaling molecule after the addition of Compound A.
