This group of stars is not in the plane of the Milky Way galaxy, and has bee... | https://en.wikipedia.org/wiki?curid=6902178 |
PP-format The (Post Processing Format) is a proprietary file format for meteorological data developed by the Met Office, the United Kingdom's national weather service.

Spur (botany) The botanical term “spur” is given to outgrowths of tissue on different plant organs. The most common usage of the term in botany refers to nectar spurs in flowers. | https://en.wikipedia.org/wiki?curid=6905141 |
Infrared cirrus are filamentary structures seen in space that emit infrared light. The name is given because the structures are cloud-like in appearance. These structures were first detected by the Infrared Astronomy Satellite at wavelengths of 60 and 100 micrometres. | https://en.wikipedia.org/wiki?curid=6905556 |
Westmorland Geological Society The is a body based in the Lake District region of the UK that aims to engage all those interested in geology, particularly in the southern Lakes.

Autoinoculation is derived from the Latin root words "autos" and "inoculate" that mean "self implanting" or "self infection" or "implanting something from oneself". can refer to both beneficial medical procedures (e.g. vaccination) as well as non-beneficial or harmful natural processes (e.g. infection or disease). One ... | https://en.wikipedia.org/wiki?curid=6917217 |
Autoinoculation This transmission or autoinoculation of the wart can occur by mechanical touching of one part of the organism to another, friction that removes a portion of the infected cells to an external surface (or another organism) and then reintroduces those cells upon contact with the body elsewhere, or when war... | https://en.wikipedia.org/wiki?curid=6917217 |
Biological constraints are factors which make populations resistant to evolutionary change. One proposed definition of constraint is "A property of a trait that, although possibly adaptive in the environment in which it originally evolved, acts to place limits on the production of new phenotypic variants." Constraint h... | https://en.wikipedia.org/wiki?curid=6920635 |
Biological constraints However, it is not clear that mere documentation of lack of change in a particular character is good evidence for constraint in the sense of the character being unable to change. For example, long-term stabilizing selection related to stable environments might cause stasis. It has often been cons... | https://en.wikipedia.org/wiki?curid=6920635 |
Biological constraints Functional coupling takes the idea that organisms are integrated networks of functional interactions (for example, the vertebral column of vertebrates is involved in the muscle, nerve, and vascular systems as well as providing support and flexibility) and therefore cannot be radically altered wit... | https://en.wikipedia.org/wiki?curid=6920635 |
