Example: "The activity can be explained by the principles of behavioral psychology, which suggest that certain actions are reinforced by rewards."
Alternatives: "the activity can be clarified" or "the activity can be justified".
The loss of activity can be explained by to poisoning of the active catalytic sites due to adsorbed organic species.
In a few cases, lack of activity can be explained straightforwardly because the mutation affects the active site or disulphide bridges.
This multienzymatic activity can be explained by the flexible substrate-binding pocket in the active site, which facilitates the binding of different substrates [ 3].
The mechanistic basis for our finding that the R96G variation caused a severe reduction in pol ι catalytic activity can be explained by a structural role of Arg96 in the active site as previously revealed.
Unusual behaviour is usually spotted – but at a time when activity can be explained away as seasonally adjusted behaviour, trend analysis can be misleading.
This increase, without loss in activity, can be explained by further lowering the amount of impurities by the produced HF and HCl.
The better catalytic activities can be explained by the high electrochemically active surface area that resulted from the smaller size and excellent dispersion of metal nanoparticles on CNT.
That New Yorkers on a dating site would be drawn to similar activities can be explained in part by a sociological principle known as homophily.
At one point, in any case, a C.I.A. dossier paused to observe: "It is important to note that Szulc's activities can be explained by the combination of his personality, ambition, and the demands on an investigative reporter for the NYT.
The enhanced photocatalytic activities can be explained by its unique morphology, larger surface area, and smaller crystallite.
The reduced activities can be explained by catabolite repression [ 38, 39].
