Linnaean taxonomy: Carl Linnaeus – domain (biology) – kingdom (biology) – phylum – class (biology) – order (biology) – family (biology) – genus – species; Three-domain system: archaea – bacteria – eukaryote – protist – fungi – plant – animal; Binomial nomenclature: scientific classification – Homo sapiens; History ...
The hierarchy of biological classification's eight major taxonomic ranks.A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Autocrine signaling is a special case of paracrine signaling where the secreting cell has the ability to respond to the secreted signaling molecule. [9] Synaptic signaling is a special case of paracrine signaling (for chemical synapses ) or juxtacrine signaling (for electrical synapses ) between neurons and target cells.
It is classified between family and class. In biological classification , the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes . An immediately higher rank, superorder , is sometimes added directly above order, with suborder directly beneath order.
[citation needed] The second theory comes from the idea that meiosis evolved from bacterial transformation, with the function of propagating genetic diversity. [9] [16] Thus, this evidence suggests that it is a question of whether cross over is linked to DNA repair or bacterial transformation, as the two do not appear to be mutually exclusive ...
[1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional units of cells.
Contact inhibition is a regulatory mechanism that functions to keep cells growing into a layer one cell thick (a monolayer). If a cell has plenty of available substrate space, it replicates rapidly and moves freely.
