A population of bees shimmers in response to a predator. Biological organisation is the organisation of complex biological structures and systems that define life using a reductionistic approach. [1]
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. On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the ...
Analysis Utility Branch Dose–response curves: Graph that shows the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time [2]
Biology. Science; Life. Properties: Adaptation – Energy processing – Growth – Order – Regulation – Reproduction – Response to environment; Biological organization: atom – molecule – cell – tissue – organ – organ system – organism – population – community – ecosystem – biosphere. Approach: Reductionism ...
Biologists can study life at multiple levels of organization, [1] from the molecular biology of a cell to the anatomy and physiology of plants and animals, and the evolution of populations. [1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use.
A non-biological entity with a cellular organizational structure (also known as a cellular organization, cellular system, nodal organization, nodal structure, et cetera) is set up in such a way that it mimics how natural systems within biology work, with individual 'cells' or 'nodes' working somewhat independently to establish goals and tasks ...
Currently, there is an increase in use of 3D cell cultures in research areas including drug discovery, cancer biology, regenerative medicine, nanomaterials assessment and basic life science research. [ 66 ] [ 67 ] [ 68 ] 3D cell cultures can be grown using a scaffold or matrix, or in a scaffold-free manner.
A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
