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]
Examples include the various stages in an organization's life cycle, phases of growth experienced by an organization during expansion and implications for these phases of growth. [16] Review of the main organizational life cycle theories, with stages, main idea and authors is given in the table below.
Particularly prominent in this regard was the work of organizational ecologists that leveraged ideas from evolutionary biology to explain the natural selection of organizations. [5] For ecologists, managers had little agency and organizational survival was determined primarily by the environment itself.
E. O. Wilson defined sociobiology as "the extension of population biology and evolutionary theory to social organization". [6]Sociobiology is based on the premise that some behaviors (social and individual) are at least partly inherited and can be affected by natural selection. [7]
The Spemann-Mangold organizer is a group of cells that are responsible for the induction of the neural tissues during development in amphibian embryos.First described in 1924 by Hans Spemann and Hilde Mangold, the introduction of the organizer provided evidence that the fate of cells can be influenced by factors from other cell populations.

The cytolytic peptide Candidalysin is produced during hyphal formation by Candida albicans; it is an example of a virulence factor from a fungus. Other virulence factors include factors required for biofilm formation (e.g. sortases) and integrins (e.g. beta-1 and 3). [7]
"Factors such as salt intake and hormonal fluctuations can lead to temporary increases or decreases in water weight, masking actual fat loss," she says. So, focus on overall trends in weight ...
Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry. Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules. Health sciences and human biology – biology of humans.
