Further, with the addition of the third phylogram, students can now address the question left unresolved from activity two where gorillas fit into the evolutionary scheme of the apes.
While phasic activity is a characteristic feature of REMS, the neural substrates driving this activity remain unresolved.
However, the enzymatic activity of PI5P4Kβ appears to have a functional role [ 12, 24], so the question of how the sequence differences in these enzymes relate to functional activity differences and why these three enzymes are so different in their activity remain unresolved, yet central to our understanding of these enigmatic lipid kinases.
The microorganisms involved in biological N2 fixation have been identified, but their relative importance and factors controlling their activity remain unresolved (Ho and Bodelier 2015).
How SUMO conjugation contributes to an increase of Gli activity remains unresolved.
How an increase in glucose concentration decreases AMPK activity is unresolved.
The mechanistic basis for oxyphenisatin acetate anti-cancer activity remains unresolved.
However, the exact mechanisms underlying the impaired vascular activity remain unresolved and there is no current scientific consensus.
Taken together, WA is a potent inhibitor of tumorigenesis both in vitro and in vivo, but the exact mechanism underlying WA anti-cancer activity remains unresolved.
Although substantial insights regarding algal H2 production exist [ 1, 43], critical aspects regarding the hydrogenase activity remain unresolved and new advances are required to define more clearly the metabolic and enzymatic processes influencing algal H2 production.
Although the molecular mechanism underlying this phenotype remains unresolved, lack of PARP activity in an HR-deficient scenario leads to the accumulation of DSBs in proliferating cells and this triggers apoptosis (Helleday, 2011).
