heat in Biological Definition

Diffusion

... spreading of something such as particles , heat , or momentum . The phenomenon is readily ... diffusion, if the temperature is constant, heat will move as quickly in one direction as in the ... diffusion. Thermal diffusion When heat travels through a material with a thermal ...

Cold-blooded

... animal will use up to 98% of its energy for heat production, an ectotherm has all this energy ... muscles of Tuna , which are warmed by a heat exchanger . In general, poikilothermic animals do not use their metabolisms to heat or cool themselves. For the same body weight ...

Warm-blooded

... can involve not only the ability to generate heat , but also the ability to cool down if ... body temperature, such as shivering (to generate heat from muscle contractions), blanching (circulatory changes to direct less heat to the skin), flushing (circulatory changes to ...

Kinetic energy

... mechanics 1.3 Relativistic mechanics 2 heat as kinetic energy 3 See also ... etc. The exact Taylor series is heat as kinetic energy heat is a form of energy due to the total kinetic ...

Polymerase chain reaction

... the following steps: Step 1 Initialization. heat the mixture at 96C for 5 minutes to ensure that ... can be added after this step. Step 2 Melting. heat at 96C for 30 seconds. For each cycle, this is ... time for the DNA to melt. Step 3 Annealing. heat at 68C for 30 seconds. Step 4 ....

Thermoregulation

... found that local differences were present, since heat production and heat loss vary considerably in different parts of the ... 1 Temperature regulation 1.1 heat gains and losses in animals 2 Types of ...

Abiogenesis

... until it was discovered that the spores of bacteria are so involved in heat-resisting membranes, that only prolonged exposure to dry, baking heat can be recognized as an efficient process of sterilization. Moreover, the presence of bacteria, or their spores, is so universal that only extreme ...

Activation energy

... minimum amount of energy. As the molecules approach their electron clouds repel. This requires energy - activation energy - and comes from the heat of the system, i.e. the translational , vibrational , and rotational energy of each molecule . If there is enough energy available, this ...

Ion gradient

... a sodium ion gradient and a potassium ion gradient. Proton gradients The proton gradient can be used as an intermediate energy storage for heat production and flagellar rotation . Additionally it is an interconvertible form of energy in active transport, electron potential generation, NADPH ...

Dialysis

... and one with the fluid, connected via flexible tubing to a Y-shaped fitting. The bag is heated to body temperature, to avoid causing cramping. Dry heat is used; common methods include microwaves , heating pads and solar radiation (often using the dashboard of a car, for instance while ...

Electrophysiology

... from a fine capillar glass tube, which is then pulled to an even finer (but still hollow of about 1 micrometer diameter for patch-clamp) tip under heat and allowed to cool. This glass "micropipette" is then filled with a chloride-based salt solution, and a chloride-coated silver wire is inserted to ...

Herpetology

... land vertebrates which are ectothermic (deriving their body temperature from their environment) rather than endothermic (deriving their body heat from an independent, internal source). This distinction applies to most (though not quite all) living tetrapods, but may break down somewhat in ...

Homeostasis

... stresses if the "natural" level of stress is not enough. Examples Thermal regulation : The skeletal muscles can shiver to produce heat if the body temperature is too low. Non-shivering thermogenesis involves the decomposition of fat to produce heat. Sweating cools the body ...

Mitochondrion

... excitotoxic neuronal injury Cellular proliferation Regulation of the cellular redox state Heme synthesis Steroid synthesis heat production (enabling the organism to stay warm) Some mitochondrial functions are performed only in specific types of cells. For example, ...

Nutrition

... babies started developing scurvy; there was a veritable plague. It turned out that the vast majority of sufferers were being fed milk that had been heat treated (as suggested by Pasteur) to control bacterial disease. Pasteurization was effective against bacteria, but it destroyed the vitamin C, ...

Redox

... ): 4Fe + 3O 2 → 2 Fe 2 O 3 . Burning of hydrocarbons to produce water , carbon dioxide , some partially oxidized forms, and heat energy . Complete oxidation of materials containing carbon produces carbon dioxide , which is linked to global warming because it absorbs ...

Prion

... as well as another mysterious heritable trait, [URE3], resulted from prion forms of certain normal cellular proteins. It was soon noticed that heat shock proteins (which help other proteins fold properly) were intimately tied to the inheritance and transmission of [PSI+] and other yeast prions. ...

Skin

... The concentration of urea is 1/130th than that of urine. Excretion by sweating is at most a secondary function to temperature regulation. heat regulation: The skin contains sebaceous glands and smooth arrector pili muscles . Aging and disease As skin ages, it becomes thinner and ...
