Descriptive science is a category of science that involves descriptive research; that is, observing, recording, describing, and classifying phenomena. Descriptive research is sometimes contrasted with hypothesis-driven research , which is focused on testing a particular hypothesis by means of experimentation .
Oryza sativa (Rice) is used as a model for cereal biology. It has one of the smallest genomes of any cereal species, and sequencing of its genome is finished. [16] (Agronomy, Molecular biology) Physcomitrella patens. Populus, genus used as a model in forest genetics and woody plant studies. It has a small genome size, grows very rapidly, and is ...
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 is a non-human species that is extensively studied to understand ...
One of the popular examples in computer science is the mathematical models of various machines, an example is the deterministic finite automaton (DFA) which is defined as an abstract mathematical concept, but due to the deterministic nature of a DFA, it is implementable in hardware and software for solving various specific problems. For example ...
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate.
A biological model is an organism or system representing a more complex biological entity. It may refer to: a model organism, a non-human species that is extensively studied to understand particular biological phenomena present in many related organisms; an in vitro model system, representing complex in vivo systems
One can use language to describe a model; however, the theory is the model (or a collection of similar models), and not the description of the model. A model of the solar system, for example, might consist of abstract objects that represent the sun and the planets. These objects have associated properties, e.g., positions, velocities, and masses.
Using a descriptive approach biologists attempt to fit a mathematical model to real data sets and infer the underlying biological principles at work from the model parameters. By contrast, mechanistic approaches create a mathematical model based on biological principles and then test how well these models fit real data sets.
