The dynamic nature of epigenetic modifications, as described by Adrian Bird, 'to register, signal or perpetuate altered activity states' through 'the structural adaptations of chromosomal regions' [ 5] allows RASF to adapt their gene expression to the highly reactive microenvironment of the rheumatoid synovium.
We observed increased fitness, higher levels of functional diversity and homogeneity, and increased cell surface hydrophobicity for biofilm adapted cells compared to the planktonic cells, indicating the physiological and structural adaptations of AKS2 cells in biofilm.
These structural adaptations seem to aid the process of sucking.
The structural adaptations of primates resulting from locomotor differences are considered in more detail in the section Locomotion, but they do not prove to be very extensive.
In regions of the Earth subjected to long dry periods, frogs must seek cover to avoid desiccation; they have behavioral and structural adaptations to conserve water.
An elegant solution came in the form of tremendous structural adaptations: new tissues and organs permitted localization of the functions of the plant body.
There live a variety of ostariophysans (Balitoridae, Sisoridae, Akysidae, Loricariidae, Astroblepidae), which exhibit fascinating structural adaptations, such as holdfast organs and specialized respiratory mechanisms.
The result of his trip to Greenland was his first book on ecological plant distribution, Om Grønlands Vegetation (1888; "On the Vegetation of Greenland"), in which he described the structural adaptations of plants to their surroundings.
Diverse bacterial species have evolved unique structural adaptations enabling them to migrate in their environmental niche.
Here we consider parametric and structural adaptations and discuss prospects and future challenges.
Structural adaptations of bone to changing mechanical loads have recently been documented during adolescence.
