In biology, homeostasis (British also homoeostasis; / h ɒ m i oʊ ˈ s t eɪ s ɪ s,-m i ə-/) is the state of steady internal physical and chemical conditions maintained by living systems. [1] This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance , being kept ...
The existence of a planetary homeostasis influenced by living forms had been observed previously in the field of biogeochemistry, and it is being investigated also in other fields like Earth system science. The originality of the Gaia hypothesis relies on the assessment that such homeostatic balance is actively pursued with the goal of keeping ...
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction. All life over time eventually reaches a state of ...
This provided direct experimental support for the second point of the "soup" theory, and it is around the remaining two points of the theory that much of the debate centers. A 2011 reanalysis of the saved vials has uncovered more biochemicals than originally discovered in the 1950s, including 23 amino acids, not just five.
Homeostatic capacity. Homeostatic capacity refers to the capability of systems to self-stabilize in response to external forces or stressors, or more simply the capability of systems to maintain homeostasis. [1][2] For living organisms, it is life's foundational trait, consisting of a hierarchy and network of traits endowed by nature and shaped ...
Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. [5] It can also be defined as the study of energy relationships and energy transformations and transductions in living organisms. [6] The ability to harness energy from a variety ...
1824 – Henri Dutrochet discovers that tissues are composed of living cells. 1838 – Protein discovered, named and recorded by Gerardus Johannes Mulder and Jöns Jacob Berzelius. 1862 – Louis Pasteur discovers the bacterial origin of fermentation. 1863 – Gregor Mendel discovers the laws of inheritance.
Anatomical terminology. [edit on Wikidata] In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine ...
