Is hibernation a physiological adaptation?
Hibernation is a physiological and behavioural adaptation whose function is to maximize energy efficiency in animals remaining in the same area the whole year round. It is an alternative to the provision of sufficient insulation to remain warm, forage continuously and sustain a constant high metabolic rate.
What is the physiological adaptation of an organism?
These adaptations are the physiological responses of an organism to the changes in its micro – and macro-environment. They confer improved ability to an organism to adapt to the changing environmental conditions by acting at cellular, physiological, metabolic, and biochemical levels. In biology, the definition of physiological adaptation goes like “changes in the basic metabolome of an organism to maintain homeostasis under the worst of environmental circumstances and trends”. Here, it becomes important for us to understand two basic terms: metabolome and homeostasis.
What is the purpose of adaptation?
In biology, adaptation refers to the adjustment or changes in behavior, physiology, and structure of an organism to become more suited or fit to an environment. According to Charles Darwin’s theory of evolution by natural selection, the organisms adapt to their environment to become better fitted to survive and pass their genes on to the next generation. However, unlike evolutionary adaptation that involves transgenerational adjustment, physiological adaptation is generally narrow in scope and involves the response of an individual to a particular, usually narrow, range of stimuli.
How many types of adaptations are there?
There are basically 3 types of adaptations namely structural adaptations, behavioral adaptations, and physiological adaptations.
What is the result of natural selection?
the ability to adapt to changes in one’s environment, will be selected by nature to pass on their genes to the next generation. So, adaptations are basically the results of natural selection.

What animals are endothermic?
Warm-blood- migrating animals such as whales and dolphins have to deal with changing temperatures in the water they travel through. Therefore, they are endothermic, or ‘warm-blooded,’ which helps them regulate their temperature depending on the surrounding water.
What is the purpose of physiological adaptation?
an aggregate of physiological reactions which forms the basis for the adaptation of the organism to changes in environmental conditions and is aimed at maintaining homeostasis, a relative stability of its internal environment. As a result of physiological adaptation, the organism becomes more resistant to cold, heat, deficiency of oxygen, changes in barometric pressure, and other factors. The study of physiological adaptation is of great importance for understanding the self-regulatory processes of the organism and its interaction with the environment. Investigations of physiological adaptation became of great practical interest in connection with manned space flight. The responses of the organism to stimulations of considerable intensity have common nonspecific features and are called the adaptation syndrome. The process of physiological adaptation to unusual and extreme conditions passes through several stages or phases. At first, decompensation (impairment of functions) prevails, then incomplete adaptation (the organism’s active search for stable conditions corresponding to the new environmental conditions), and, finally, the phase of rather stable adaptation. This can be well observed, for example, in the case of adaptation to high altitudes. The changes in conditions in this case are complex, but most important is the insufficient partial pressure of oxygen connected with the overall decrease in barometric pressure. During ascent to high altitudes, one observes dizziness, disturbances of visual and auditory perceptions, dyspnea, and other phenomena characteristic of altitude sickness. As a result of physiological adaptation, the decompensation phenomena gradually subside, and adaptation to these unusual conditions sets in: the number of erythrocytes increases (in man, from 4–5 million to 8 million per cubic millimeter); the oxygen-binding capacity of the hemoglobin rises; pulmonary ventilation intensifies; and cardiac activity, the condition of the nervous system, and other functions become normalized.

The study of physiological adaptation is of great importance for understanding the self-regulatory processes of the organism and its interaction with the environment .
What is the physiological adaptation of the visual analyzer?
Physiological adaptation of the analyzers is connected with changes in the sensitivity of the peripheral sense organs (the receptors) and with processes occurring in the central nervous system . Thus, light adaptation, caused by prolonged exposure to bright light, leads to a decrease of the light sensitivity of the eyes, and dark adaptation leads to its increase. In darkness, the sensitivity of the eyes to light increases many thousandfold within an hour; this change is due both to the restoration of visual pigments and to changes in the neural elements and nerve cells of the cerebral cortex. Physiological adaptation in the auditory analyzer is manifested in an increased threshold of stimulation under the influence of high-intensity sound. A gradual change in sensitivity—that is, physiological adaptation—is also observed during the action of cold, heat, and other stimuli on the skin. Very important in this process is the rate of increase of the intensity of the stimulus.
What is the return of an organism to its original condition after physiological adaptation?
The return of the organism to its original condition after physiological adaptation is called deadaptation. Of great biological importance is the physiological adaptation of the analyzers (sometimes called adaptation of the receptors or sense organs) to the action of specific stimuli—for example, the adaptation of the visual analyzer to light ...
What is the function of the nervous system in physiological adaptation?
