“Chemistry experiments with seaborgium have firmly placed it in group 6 as a heavier homologue to tungsten.”
“Ovaries are located in the stalk of pedunculate barnacles and its homologue or in the basal lining of the mantle cavity in sessile barnacles.”
“They are intermediates in such reactions as the change of a carboxylic acid to its next highest homologue or to a derivative of a homologous acid such as an ester or an amide.”
homologation
(organic chemistry) Any reaction that converts a compound into the next member of a homologous series, usually by lengthening a carbon chain
“Plate homologies between the two basic types of aboral cup construction, monocyclic and dicyclic, were not always as had traditionally been assumed.”
“However helpful this removal can be, there needs also to be a cohesive model of homologies that can draw upon the integration of morphology, ontogeny, and paleontology.”
“The wings of birds, forelimbs of a lizard and human arms are homologies, because they are all derived from the same primitive structure in the common ancestor of these groups.”
