Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization. Behavioural adaptations are inherited systems of behaviour, whether inherited in detail as instincts, or as a neuropsychological capacity for learning. Examples include searching for food, mating, and vocalizations.
Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.
The stapes was thought to be just a structural support between the palate and the stapedial plate of the braincase. [9] In the Acanthostega, it is likely that due to the otic capsule of the brain case being mesial to the stapedial plate, sound was picked up from the palate or the otic notch to allow for rudimentary hearing. It was able to ...
In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
Many species have evolved structural adaptations to maximize wind dispersal potential. Common examples include plumed, winged, and balloon-like diaspores. [21] Plumed diaspores of the dandelion, Taraxacum officinale. Plumed diaspores have thin hair-like projections that lift them up higher. [21]
This adaptation is primarily found in semiaquatic species, and has convergently evolved many times across vertebrate taxa. Unlike other waders , the pied avocet has webbed feet, and can swim well. It likely arose from mutations in developmental genes that normally cause tissue between the digits to apoptose .
These plants possess structural adaptations in the form of domatia where ants can shelter, and food bodies and extrafloral nectaries that provide ants with food. [1] In exchange for these resources, ants aid the myrmecophyte in pollination, seed dispersal, gathering of essential nutrients, and defense. [1]
A plastron is a type of structural adaptation occurring among some aquatic arthropods (primarily insects), a form of inorganic gill which holds a thin film of atmospheric oxygen in an area with small openings called spiracles that connect to the tracheal system.
