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.
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 ...
Signalling theory. By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.
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.
A biological system is a complex network which connects several biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. [ 1 ] Examples of biological systems at the macro scale are populations of organisms.
Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology[b][1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems. It involves the use of computer simulations of ...
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]
Exhalation delivery systems (EDS) deliver medications to the internal nose. Developed in 2006, [1] EDS devices use the patient's exhaled breath to propel medication, such as steroids, [1] into the nasal cavities. The method can deliver medication deeper into the nasal passages than intranasal sprays, [1] and at a lower pressure than nasal ...
