This is somewhat surprising to us as instructors; the videos contain detailed explanation to the problems, and the first attempt correct rate for non-video viewers ranges from 30 to 70%%.
A noteworthy observation is that, although the videos contain detailed explanation to the problem, only a small fraction of students chose to watch the video, and this fraction is different for different problems.
Here an explanation to this problem is shown considering the principle of "replication parsimony" genetic information tends to be utilized in a parsimonious way under selection pressure, due to its replication cost (e.g., in the RNA world, nucleotides and ribozymes for RNA replication).
Nobody can give a simple and clear explanation to capture the problems described above in a theoretical framework (using numerical simulations, many qualitative and quantitative but sometimes very complex studies have investigated effects of antiviral drugs [3], [8], [9], [10], [12], [26]).
The majority of students (41%%) found the consultations very helpful and good explanations to their problems were provided.
The app then gives you a step-by-step explanation to solve the problem.
Convex-hull heuristics could provide a parsimonious explanation to complex routing problem solving by traplining animals, without necessarily requiring a sophisticated cognitive representation of space.
At last, we give an explanation to a long-term problem in GR index model that GR index is generally larger than the actual shale volume.
One explanation to why emotional and behavioral problems continue to adulthood, when they are associated with TMD-pain, could be that cognitive and nociceptive systems already affected by pain once, easily can recall these associations [27].
Some mechanists argue that the covering law model of constitutive explanation has problems analogous to those that beset the covering-law model of etiological explanations.
