Graph that shows voltage fluctuations resulting from ionic current within the neurons of the brain [3] Neuroscience: Electrocardiogram: Graph of voltage versus time of the electrical activity of the heart [4] using electrodes placed on the skin: Physiology: Identification key: Used to identify a specimen organism from a set of known taxa. [5 ...
The iterative cycle inherent in this step-by-step method goes from point 3 to 6 and back to 3 again. While this schema outlines a typical hypothesis/testing method, [ 53 ] many philosophers, historians, and sociologists of science, including Paul Feyerabend , [ h ] claim that such descriptions of scientific method have little relation to the ...
The development of biological databases enables storage and management of biological data with the possibility of ensuring access for users around the world. They are useful for researchers depositing data, retrieve information and files (raw or processed) originated from other experiments or indexing scientific articles, as PubMed .
A model of a biological system is converted into a system of equations, although the word 'model' is often used synonymously with the system of corresponding equations. The solution of the equations, by either analytical or numerical means, describes how the biological system behaves either over time or at equilibrium. There are many different ...
Felsenstein [1] proposed the first general statistical method in 1985 for incorporating phylogenetic information, i.e., the first that could use any arbitrary topology (branching order) and a specified set of branch lengths. The method is now recognized as an algorithm that implements a special case of what are termed phylogenetic generalized ...
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. [1] Particularly from the year 2000 onwards, the concept has been used widely in biology in a variety of contexts.
RNA folding problem: Is it possible to accurately predict the secondary, tertiary and quaternary structure of a polyribonucleic acid sequence based on its sequence and environment? Protein design : Is it possible to design highly active enzymes de novo for any desired reaction?
Life history theory (LHT) is an analytical framework [1] designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. [2] It is a theory of biological evolution that seeks to explain aspects of organisms' anatomy and behavior ...
