Models always have limited parameters and constraints. Models typically simplify a complex system into variables that can be controlled.
In this case, we were trying to see what variables increased moth survival based on their color, camouflage, and predation.
What are some variables in the peppered moth simulation that were not addressed?

Other variables that could have been taken into account are size, variability of shape in its wings and degree of darkening in its wings.

Explanation:

Of the three named variables, I believe that the degree of darkening is the most important since in this way we can realize the association of its color with environmental pollution, and thus be able to look for a cause-effect relationship.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
