Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Models have ____ limitations that we need to recognize.
A
non-important
B
important
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Since models only approximate natural phenomena, they are inherently inexact. The mathematical description can be imperfect and/or our understanding of phenomenon may not be complete.

Detailed explanation-2: -Among the weaknesses of cellular models is the inability to reflect the role of complex decision making by human agents. However, cellular frameworks may be combined with Markov models, in which transition rules are treated probabilistically and may be conditioned by temporal lags in cell response.

Detailed explanation-3: -It may not represent a molecule in solution, whose geometry will be different. It can only represent one conformer, when we want to consider several. For a large model, may not be able to see in to the active site. Cannot easily measure distances, angles, etc. from it: for these need tables of data as well.
