For example, genomes can be further subdivided into a hierarchy of genes. [4] Each level in the hierarchy can be described by its lower levels. For example, the organism may be described at any of its component levels, including the atomic, molecular, cellular, histological (tissue), organ and organ system levels.
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 ...
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.
Quantum biology – The field of quantum biology applies quantum mechanics to biological objects and problems. Decohered isomers to yield time-dependent base substitutions. These studies imply applications in quantum computing. Agronomy and agriculture; Many biophysical techniques are unique to this field. Research efforts in biophysics are ...
[6] [7] Other than this, within the scope of business, the organizational life cycle and business life cycle can be distinguished by their primary focus. The organizational life cycle is primarily concerned with the internal development and evolution of the organization itself, while the business life cycle is primarily concerned with the ...
Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). [ 3 ] There are three major mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct).

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]
