Biological process

A biological process is a process of a living organism. Biological processes are made up of any number of chemical reactions or other events that results in a transformation. Many of these processes have psychological implications.

Regulation of biological processes occurs where any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.
 * Physiological process, those processes specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms.
 * Reproduction
 * Digestion
 * Response to stimulus, a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus.
 * Interaction between organisms. the processes by which an organism has an observable effect on another organism of the same or different species.
 * Also: fertilisation, germination, tropism, hybridisation, metamorphosis.
