Before revision:  The homogeneity of the communities depends on the scale selected . We use a novel test and two independent characterizations of protein function to determine the functional homogeneity of communities.
After revision:  The homogeneity of the communities depends on the scale selected , and that almost all proteins lie in a functionally homogeneous community at some scale. We judge functional homogeneity using a novel test and two independent characterizations of protein function to determine the functional homogeneity of communities.
