Culture and biology certainly influence each other, and it is very likely that both influence sexual drive. However, whether biological or cultural factors best explain the reproduction cycle has long been debated in the literature, with biological explanations dominating the argument1. The biological ...
Bifurcation Analysis of a Model of Mitotic Control in Frog Eggs In addition to unique, stable steady states (cell cycle arrest) and limit cycle oscillations (autonomous, periodic cell division), we find parameter ... MT Borisuk,JJ Tyson - 《Journal of Theoretical Biology》 被引量: 271发表:...
Biology teaching at senior school level in the United Kingdom is dominated by the functional approach which gives little prominence to life cycles. It is argued that life cycles and the concept of the four-dimensional organism should be the single most important idea in teaching at this level....

Taxonomy is important in conservation: a preliminary reassessment of Philippine species-level bird taxonomy Alpha taxonomy involves delineation of the basic unit of biology: the species. The concepts bywhich we define species, however, have been controversial, wi... PETERSON,A Townsend - 《Bird Cons...
Using adeno-associated virus (AAV)-mediated stimulation of PKA and PP1–calcineurin activities, we show that PKA is a wake-promoting kinase, whereas PP1 and calcineurin function as sleep-promoting phosphatases. The importance of these phosphatases in sleep regulation is supported by the marked ...
