Physiology, question history

It is wise to steer clear of these difficult questions, but history suggests that even if these particular hypotheses are not affirmed by further physiological study, the study will be fruitful in other unanticipated ways. In fact, one could argue that the agenda of cognitive neuroscience today... 

Despite this plethora of information regarding the physiological ecology of Phaeocystis, fundamental interactions between life history traits and system ecology are poorly understood. Research summarized here, and described in the various papers in this special issue, derives from a central question how do physical (light, temperature, particle distributions, hydrodynamics), chemical (nutrient resources, infochemistry,... 

Proteins of the transferrin family share a common evolutionary history, which has resulted in the presence of two homologous halves to each molecule (Sections III.A and III.B.l). Except for the two outliers, melanotransferrin and M. sexta transferrin, each also has two metal binding sites. This raises a number of questions, which have been the subject of much debate over the years (1,3,16,17). Why are there two sites How similar are they, and do the differences between them have any functional or physiological significance Is there any cooperativity between them ...
