Ebriida
The Ebriales (see taxobox for synonyms) is a group of phagotrophic flagellate eukaryotes present in marine coastal plankton communities worldwide. '' Ebria tripartita'' is one of two (possibly four) described extant species in the Ebriales. Members of this group are named for their idiosyncratic method of movement (''ebrius'', "drunk"). Ebriids are usually encountered in low abundance and have a peculiar combination of ultrastructural characters including a large nucleus with permanently condensed chromosomes and an internal skeleton composed of siliceous rods. The taxonomic history of the group has been tumultuous and has included a variety of affiliations, such as silicoflagellates, dinoflagellates, ' radiolarians' and 'neomonads'. However, molecular phylogenies place them within Cercozoa Cercozoa (now synonymised with Filosa) is a phylum of diverse single-celled eukaryotes. They lack shared morphological characteristics at the microscopic level, and are instead united by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Families
Family (from ) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). It forms the basis for social order. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary purpose of attachment, nurturance, and socialization. Anthropologists classify most family organizations as matrifocal (a mother and her children), patrifocal (a father and his children), conjugal (a married couple with children, also called the nuclear family), avuncular (a man, his sister, and her children), or extended (in addition to parents, spouse and children, may include grandparents, aunts, uncles, or cousins). The field of genealogy aims to trace family lineages through history. The family is also an important economic unit studied in family economics. The word "families" can be used metaphorically to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
