31. In yeast signal transduction, a yeast cell releases a mating factor which
(A) diffuses through the membranes to opposite type of cells, causing them to producefactors that initiate long-distance migrations
(B) binds to receptors on the membranes of opposite type of yeast cells
(C) passes through the membranes of opposite cell type, binds to DNA, and initiatestranscription
(D) acts back on the same cell type that secreted the mating factor, changing its celldivision
(E) Changes the shape of the opposite type of yeast cells
