Question

Chemotaxis is a process by which cells migrate toward higher concentrations of a signaling molecule. The signaling molecule binds cell-surface receptors that result in actin polymerization at the cell membrane. Actin polymerization results in the formulation of filamentous actin that exerts a force and leads to protrusion of the leading edge. A researcher tested Compound A on chemotaxing cells and measured the relative amount of filamentous actin found in the cells at different times.

Use the EGF Pathway passage to answer the questions.

Part C

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.

My solution to Part C is (b) the cell moved away from the soure of signaling molecule only after the addition of Compound A. But this is not Bartleby's answer. CAn you please explain why this is wrong? Thanks!
