If either of these scenarios is true then two things occur – firstly, we should start calling the filaments of ornithischians (and maybe pterosaurs too) 'feathers'feathers
The peak of pollinator visits occurred firstly, which may allow the pollinator to access nectar and pollen loads before they are exploited by thieves.
Regarding the trouble that occurred, firstly I think the standard of reffing in the US Open Cup in general, is terrible, so it wasn't surprising that with San Jose pressing in the last ten minutes, and both sides having terrible decisions going against them, that the ref lost control of the game.
This may occur, firstly, when the presence of a particular genotype has a "disproportionate" effect on some key process that affects species diversity, e.g. litter decomposition rates in populations of Populus [5].
As H-bonds broke, the resistance to stretching would be provided gradually by the main chain, whose local denaturation might occur firstly at C-terminal or N-terminal and then spread to other region (Fig. 1 B); the higher the level of the survival ratio of main-chain H-bonds, the more the resistance of the main chain to the extension.
We used the model to calculate the risk of transmission occurring, firstly between two patients in adjacent beds, and then between patients in a four-bedded bay.
In liverworts, a similar pattern was encountered but decreases in rates of diversification occurred firstly in a cool climate mode (ca. 184 Ma) and secondly during a warm climate mode (ca. 99 Ma).
These processes occur firstly in order to anchor the fetus to the maternal endometrium and secondly to remodel and replace the normal musculo-elastic structure of the maternal spiral arteries with fibrinoid material containing trophoblast.
A recall bias is unlikely to have occurred since firstly, cases and controls shared the same cardiac condition, and secondly the association between benfluorex and mitral regurgitation was not known.
