Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1] In the medical context, outside of specialized branches of biomedicine, morphological adaptations are not always referenced to the fundamental cellular level, but are observed and assessed at the level of tissues and organs.
The adaptive traits may be structural, behavioural or physiological. 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.
The structural stability of the nest is provided by a mesh of moss and spider silk. The tiny leaves of the moss act as hooks and the spider silk of egg cocoons provides the loops; thus forming a natural form of velcro. [20] The tit lines the outside with hundreds of flakes of pale lichens – this provides camouflage.
Change in the shape of the hip may have led to the decrease in the degree of hip extension, an energy efficient adaptation. [1] [14] The ilium changed from a long and narrow shape to a short and broad one and the walls of the pelvis modernized to face laterally. These combined changes provide increased area for the gluteus muscles to attach ...
The structural adaptations of these two resurrection plants are very similar. They can be found on the grounds of Bulgaria and Greece. Plants absorb water from the soil, which then evaporates from their shoots and leaves; this process is known as transpiration .
The wood frog has evolved traits that prevent their cells from being damaged when frozen and thawed out. The wood frog has developed various adaptations that allow it to effectively combat prolonged ischemia/anoxia and extreme cellular dehydration. One crucial mechanism utilized by the wood frog is the accumulation of high amounts of glucose ...
Marsupial moles, the Notoryctidae / n oʊ t ə ˈ r ɪ k t ɪ d iː / family, are two species of highly specialized marsupial mammals that are found in the Australian interior. [2] They are small burrowing marsupials that anatomically converge on fossorial placental mammals, such as extant golden moles (Chrysochloridae) and extinct epoicotheres ().
This nudibranch displays a stunning set of colors: the body is purple, the cerata are orange and the rhinophores are scarlet. The neon orange appendages on the back of Flabellinopsis iodinea are the cerata which extract oxygen from the sea water they are surrounded by and live in.
