WebOne stains the mesoderm tissue blue; the other stains ectoderm tissue red. If the researcher exposes an'embryo from Cnidaria or Ctenophora to both stains, and then rinses away the excess stain, what should occur? The embryo will have both a blue-stained and red-stained tissue layer. O The embryo will have only a red-stained tissue layer. WebThey also only have two tissue layers, an outer epidermis and an inner cell layer. Cnidarians come in two forms: the polyp, which is a stationary cylindrical body with tentacles projecting...
