81Evolution of flagella — The evolution of flagella is of great interest to biologists because the three known varieties of flagella (eukaryotic, bacterial, and archaebacterial) each represent an extremely sophisticated cellular structure that requires the interaction of… …
82Methanogen — Methanopyrus kandleri Methanogens are microorganisms that produce methane as a metabolic byproduct in anoxic conditions. They are classified as archaea, a group quite distinct from bacteria. They are common in wetlands, where they are responsible …
83Exonuclease — Exonucleases are enzymes (found as individual enzymes, or as parts of larger enzyme complexes) that cleave nucleotides one at a time from an end of a polynucleotide chain. These enzymes hydrolyze phosphodiester bonds from either the 3 or 5… …
84Voltage-gated ion channel — Voltage gated ion channels are a class of transmembrane ion channels that are activated by changes in electrical potential difference near the channel; these types of ion channels are especially critical in neurons, but are common in many types… …

86Abiotic component — In biology, abiotic components are non living chemical and physical factors in the environment. Abiotic phenomena underlie all of biology, but at the same time both are better forgotten in the direct analysis of life as such. More generally, the… …
87Macrodevelopment — is a biological hypothesis that proposes over millions of years the biosphere has nonlinearly unfolded taxa from generic forms to specific forms, in a manner analogous to the way in which a biological embryo develops in the womb. The theory was… …
88Microecosystem — Microecosystems can exist in locations which are precisely defined by critical environmental factors within small or tiny spaces. Such factors may include temperature, pH, chemical milieu, nutrient supply, presence of symbionts or solid… …
