comment Why is the gene regulation in eukaryotic cells needs multiple level of control than in prokaryotic cells?
@WYSIWYG I rephrased the question to make is less broad. I may still be unclear since I am poor in Biological vocabulary/terms.

If nothing else, they can probably make a throne for their queen out of this flexible material!

comment Mechanism behind negative conductance of ion channels
@AliceD. Sorry for the confusion. I've made some edits. A figure added to question shows one mechanism by which negative conductance is obtained.

comment Cell energy consumption and food intake
Does efficiency of digestive system play a part? If it is 10% efficient, then consumption should be doubled.

comment Why can't the human eye focus blue light?
It might, then the suggestion would be that we dont have strong lateral inhibition among blue detector neurons. just a hypothesis.

comment Why can't the human eye focus blue light?
Interesting observation. In addition to aberration, which I suspect to play very little part, I'd hypothesis the role of neural network in visual pathway. What happens when only blue light detectors fires in this network? Additionally, blue light detectors usually have 1/3 of sensitivity than other colors detectors. Also if a blue-detector is tightly connected with other blue-detectors (I don't know if this is true) then exciting one with also excite few others thereby giving a blurry image.

comment Single long axon vs serial neurons
If you want to reduce the variance in signal transmission with n serial steps, then you need to add more steps. Therefore to achieve signal transmission with really low variance, you either want a single axon (case A) or really lot of them connected in series (case B). May be overall, case A is not so bad compared to case B not to be selected for.
