Refimprove date July 2007 Several animal groups have undergone aquaticadaptation , going from being purely terrestrial animals to living at least part of the time in water. The adaptation biology adaptation s in early speciation tend to develop as the animal ventures into water in order to find available food. As successive generations spend more time in the water, natural selection causes the acquisition of more adaptations. Animals of later generations may spend the majority of their life in the water, coming ashore for mating. Finally, fully adapted animals may take to mating and birthing in water. Anapsid main Anapsid Archelon is a type of giant sea turtle dating from the Cretaceous Period, now long extinct. Its smaller cousins survive as the sea turtles of today. Mesosaurus and other mesosaurids were another group of anapsid reptiles to secondarily return to the sea, eschewing shells, and are also long extinct. Diapsid main Diapsid Living at the same time as, but not closely related to, dinosaurs, the mosasaur s resembled crocodiles but were more strongly adapted to marine life.

Confusing date September 2008 lowercase Functional magnetic resonance imaging adaptation fMRIa is an increasingly used method of functional magnetic resonance imaging which takes advantage of the brain changes which occur in response to long exposure to some evocative stimulus. If Stimulus 1 S sub 1 sub excites a certain neuronal population, repeated exposure to S sub 1 sub will result in subsequently attenuated responses. This Neural adaptationadaptation may be due to neural fatigue or may be due to coupled hemodynamic processes. However, when S sub 1 sub is followed by a unique stimulus, S sub 2 sub , the response amplitudes should not be attenuated as a fresh sub population of neurons is excited. Using this technique can allow researchers to determine if the same or unique neuronal groups are involved in processing two stimuli. ref name Krekelberg Krekelberg, B, Boynton, G.M., & van Wezel, R.J.A. 2006 .

The maintenance of proper cell membrane fluidity is of critical importance for the function and integrity of the cell biology cell , essential for the mobility and function of embedded proteins and lipids , diffusion of proteins and other molecules laterally across the membrane for signaling reactions, and proper separation of membranes during cell division . A fundamental biophysical determinant of membrane fluidity is the balance between saturated fat saturated and saturated fat unsaturated fatty acids . Regulating membrane fluidity is especially important in poikilothermic organisms such as bacteria , fungi , protists , plants , fish and other Poikilotherm cold blooded animals that cannot regulate their own body temperatures. The general trend is an increase in unsaturated fatty acids at lower growth temperatures and an increase in saturated fatty acids at higher temperatures. This compositional adaptation of membrane lipids, called homeoviscous adaptation , serves to maintain the correct membrane fluidity at the new conditions.

Chromatic adaptation is one aspect of Human visual system vision that may fool someone into observing a color based optical illusion , such as the same color illusion . An object may be viewed under various conditions. For example, it may be illuminated by sunlight, the light of a fire, or a harsh electric light. In all of these situations, human vision perceives that the object has the same color an apple always appears red, whether viewed at night or during the day. On the other hand, a camera with no adjustment for light may register the apple as having varying color. This feature of the visual system is called chromatic adaptation, or color constancy when the correction occurs in a camera it is referred to as white balance . Though the human visual system generally does maintain constant perceived color under different lighting, there are situations where the relative brightness of two different stimuli will appear reversed at different illuminance levels.

In visual perception ocular physiology , adaptation is the ability of the human eye eye to adjust to various levels of darkness and light. Efficacy The human eye can function from very dark to very bright levels of light its sensing capabilities reach across nine order of magnitude orders of magnitude . This means that the brightest and the darkest light signal that the eye can sense are a factor of roughly 1,000,000,000 apart. However, in any given moment of time, the eye can only sense a contrast vision contrast ratio of one thousand. What enables the wider reach is that the eye adapts its definition of what is black. The light level that is interpreted as black can be shifted across six orders of magnitude a factor of one million. The eye takes approximately 20 30 minutes to fully adapt from bright sunlight to complete darkness and become ten thousand to one million times more sensitive than at full daylight.

The brain plays a crucial role in the inner workings of vision. The world that one perceives is processed via the brain. Images sensed through the eyes is relayed to the visual cortex of the brain, and if vision is altered slightly, the brain accounts for the difference and will allow one to perceive the world as normal.

Link adaptation , or adaptive coding and modulation ACM , is a term used in wireless communications to denote the matching of the modulation , Channel coding coding and other Signalling telecommunication signal and Communications protocol protocol parameters to the conditions on the radio link e.g. the pathloss , the Interference communication interference due to signals coming from other transmitters, the sensitivity of the receiver, the available transmitter power margin, etc. . For example, Enhanced Data Rates for GSM Evolution EDGE uses a rate adaptation algorithm that adapts the modulation and coding scheme MCS according to the quality of the radio channel, and thus the bit rate and robustness of data transmission. The process of link adaptation is a dynamic one and the signal and protocol parameters change as the radio link conditions change for example in HSDPA in UMTS this can take place every 2 ms. Adaptive modulation systems invariably require some channel state information at the transmitter. This could be acquired in time division duplex systems by assuming the channel from the transmitter to the receiver Information Theory receiver is approximately the same as the channel from the receiver to the transmitter. Alternatively, the channel knowledge can also be directly measured at the receiver, and fed back to the transmitter. Adaptive modulation systems improve transmission rate rate of transmission , and or bit error rate s, by exploiting the channel state information that is present at the transmitter. Especially over fading channel s which model wireless propagation environments, adaptive modulation systems exhibit great performance enhancements compared to systems that do not exploit channel knowledge at the transmitter. Example In HSDPA link adaptation is performed by choice of modulation type the link can employ QPSK for noisy channels and Quadrature amplitude ... using QPSK and 1 3 coding rate but the information bit rate drops to about 2.4 megabit s.

E. & McCance, K. L. 2008 . Understanding Pathophysiology , Ed 4, p. 62 65. ref The adaptation may be physiologic al normal or pathologic al abnormal . Five major types of adaptation include atrophy , hypertrophy , hyperplasia , dysplasia , and metaplasia . Atrophy is a decrease in cell size. If enough cells in an organ atrophy the entire organ will decrease in size. Thymus atrophy during early Human development biology human development childhood is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse commonly called disuse atrophy . Tissue and organs especially susceptible to atrophy include skeletal muscle, cardiac muscle, Secondary sex characteristic secondary sex organ s, and the brain . Hypertrophy is an increase in cell size. If enough cells of an organ hypertrophy so will the whole organ. The heart and kidneys have increased susceptibility to hypertrophy. Hypertrophy involves an increase in intracellular protein rather than cytosol intracellular fluid . Hypertrophy may be caused by Biomechanics mechanical signals e.g., stretch or Tropic hormone trophic signals e.g., growth factors . An example of physiologic hypertrophy is in skeletal muscle with sustained weight bearing exercise. An example of pathologic hypertrophy is in cardiac muscle as a result of hypertension . Hyperplasia is an increase in the number of cells. It is the result of increased cell mitosis , or division. The two types of physiologic hyperplasia are Compensatory growth organ compensatory and hormonal . Compensatory hyperplasia permits tissue and organ regeneration. It is common in epithelial cells of the Epidermis skin epidermis and intestine ... adaptation rather, it is thought to be related to hyperplasia and is sometimes called atypical ... more details
