Based on this sensitivity analysis, if you were asked to use this model to decide between the large far and small near patch configurations for butterflies, and you could send a field biologist out to collect data before you settled on which parameter settings to use in your simulations, what would you tell the biologist is the most important field data to collect?

Molecules called lipids have long hydrocarbon chains that determine the way they act. they can be fats, oils, or hormones, and even exist in our cell membranes 

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
