Which result of experiment 1 supports the hypothesis that cell-to-cell communication is involved in the determination of cell fate? the fate of an isolated ab cell differs from that of an ab cell in an intact embryo. the fate of an isolated p1 cell is indistinguishable from that of a p1 cell in an intact embryo. at the two-cell stage, isolated blastomeres can divide and differentiate. several different blastomeres can produce both neurons and muscle tissue.
