Escherichia coli is a gram-negative prokaryotic model organism Drosophila melanogaster, one of the most famous subjects for genetics experiments Saccharomyces cerevisiae, one of the most intensively studied eukaryotic model organisms in molecular and cell biology. A model organism (often shortened to model) is a non-human species that is ...
A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1] An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome ), which is studied to better understand ...
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 ...
An alternative method where incorrect answers are only moved back by one box. The Leitner system [1] [2] [3] is a widely used method of efficiently using flashcards that was proposed by the German science journalist Sebastian Leitner in 1972. [4] [5] It is a simple implementation of the principle of spaced repetition, where cards are reviewed ...
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.
Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. Bronfenbrenner developed the foundations of the theory throughout his career, published a major statement of the theory in American Psychologist, articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of Human ...
Modelling biological systems. 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.
The Lotka–Volterra equations, also known as the Lotka–Volterra predator–prey model, are a pair of first-order nonlinear differential equations, frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey. The populations change through time according to the pair of ...
