Query: Perfect fluids with $\omega=\mathrm{const}$ as sources of scalar
  cosmological perturbations   We make a generalization of a self-consistent first-order perturbation
scheme, being suitable for all (sub-horizon and super-horizon) scales, which
has been recently constructed for the concordance cosmological model and
discrete presentation of matter sources, to the case of extended models with
extra perfect fluids and continuous presentation. Namely, we derive a single
equation determining the scalar perturbation and covering the whole space as
well as define the corresponding universal Yukawa interaction range. We also
demonstrate explicitly that the structure growth is suppressed at distances
exceeding this fundamental range.
