Complex systems. Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology -based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research.
Frequency. 1 in 5,000 [1] Ehlers–Danlos syndromes (EDS) are a group of 13 genetic connective-tissue disorders. [7] Symptoms often include loose joints, joint pain, stretchy velvety skin, and abnormal scar formation. [1] These may be noticed at birth or in early childhood. [3]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Developmental systems theory (DST) is an overarching theoretical perspective on biological development, heredity, and evolution. [1] It emphasizes the shared contributions of genes, environment, and epigenetic factors on developmental processes. DST, unlike conventional scientific theories, is not directly used to help make predictions for ...
Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships, graphically represented in ...
Macroevolution addresses the evolution of species and higher taxonomic groups (genera, families, orders, etc) and uses evidence from phylogenetics, [5] the fossil record, [9] and molecular biology to answer how different taxonomic groups exhibit different species diversity and/or morphological disparity.
Class (biology) The hierarchy of biological classification 's eight major taxonomic ranks. A phylum contains one or more classes. Intermediate minor rankings are not shown. In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders.
Single-wavelength anomalous diffraction (SAD) is a technique used in X-ray crystallography that facilitates the determination of the structure of proteins or other biological macromolecules by allowing the solution of the phase problem.
