In biology a thermal optimum describes the ideal boundaries for biological processes such as growth and development, and is usually characteristic of a species or population. Most biological processes are dependent upon enzymatic activity that can be impacted by the organism's body temperature, which in term is a function of the organism's ...
Thermoregulation. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
In biology, kleptothermy is any form of thermoregulation by which an animal shares in the metabolic thermogenesis of another animal. It may or may not be reciprocal, and occurs in both endotherms and ectotherms. [1] One of its forms is huddling. However, kleptothermy can happen between different species that share the same habitat, and can also ...
Hyperthermophile. A hyperthermophile is an organism that thrives in extremely hot environments—from 60 °C (140 °F) upwards. An optimal temperature for the existence of hyperthermophiles is often above 80 °C (176 °F). [1] Hyperthermophiles are often within the domain Archaea, although some bacteria are also able to tolerate extreme ...
Homeothermy. The group that includes mammals and birds, both "warm-blooded" homeothermic animals (in red) is polyphyletic. Homeothermy, homothermy or homoiothermy [1] is thermoregulation that maintains a stable internal body temperature regardless of external influence. This internal body temperature is often, though not necessarily, higher ...
Thermotropism. Thermotropism or thermotropic movement is the movement of an organism or a part of an organism in response to heat or changes from the environment's temperature. A common example is the curling of Rhododendron leaves in response to cold temperatures. Mimosa pudica also show thermotropism by the collapsing of leaf petioles leading ...
Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1] In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative temperature . Thermostable ...
The Entertainment Software Rating Association ( Persian: اسرا) ( ESRA) is a governmental video game content rating system that is used in Iran. Games that have been exempt from the rating are de facto banned from sale in Iran. +3 – Ages 3 and over. +7 – Ages 7 and over. +12 – Ages 12 and over.
