Microevolution is the change in allele frequencies that occurs over time within a population. [1] This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Evolutionary processes evolution; microevolution: adaptation – selection – natural selection – directional selection – sexual selection – genetic drift – sexual reproduction – asexual reproduction – colony – allele frequency – neutral theory of molecular evolution – population genetics – Hardy–Weinberg principle ...
[5] In evolutionary developmental biology, scientists look at how the different processes in development play a role in how a specific organism reaches its current body plan. The genetic regulation of ontogeny and the phylogenetic process is what allows for this kind of understanding of biology.
The Urmetazoan is the hypothetical last common ancestor of all animals, or metazoans.It is universally accepted to have been a multicellular heterotroph — with the novelties of a germline and oogamy, an extracellular matrix (ECM) and basement membrane, cell-cell and cell-ECM adhesions and signaling pathways, collagen IV and fibrillar collagen, different cell types (as well as expanded gene ...
Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. [1]
Process of separating individual living cells from a solid block of tissue or cell suspension: Cell biology: Centrifugation: Use of centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity, and rotor speed: Cell biology, Biochemistry: CRISPR gene editing
Built directly off his previous paper titled 'Punctuated equilibria', [9] the stasis pattern of life represents periods of 'dynamic, non-regular oscillation' [5] of intra-population variation. Stasis does not mean a species collective genome is stable, but instead still are in constant flux and variation, just in non-specific directions.
