okay... so the UCPs disrupt the proton gradient. This means less ATP is made because they now flow freely (but in equilibrium) between the two spaces. I would GUESS that glycolysis and krebs would need to increase to make up for the energy deficit. this however, is only a guess. but it makes sense, ...

as in uncoupling the electron transport chain? This is used to create excess heat. Instead of making more ATP, the excess energy generates heat. Skunk cabbages use this to melt snow around them to take a place in their niche. Look it up if that's what you meant... if not, sorry :P

i would say go with d
though it isn't necessarily termed "inducible conrol", it is inducible (as you know)
if this is a test, it's testing what you know, and it probably wants to see that

that might help... they do look similar to human lumbars

i think it may be 4n... here's why
the tetraploid plant's pollen grain would then be diploid, no?
so 2n combines with the polar nuclei... 2n+n+n= 4n
normally endosperm are triploid, and i thought they always were... but apparently that's not always the case. if you haven't, look here

interestingly enough, there is a lot of controversy surrounding the one instance you mentioned... i remember reading something on scales and feathers. It mentioned something about scutes and how there are different types of scales, like how it was easier, when inhibiting/ repressing certain genes to...

well, if it is uncoupled, then the energy used to drive H+ across the membrane would then be released as heat. Incidentally, skunk cabbage does this in order to heat up and melt the snow around it. and as to the oxygen, i think it would still be needed

look up that general, dare i say it, BRANCH of plants (haha, get it?)
they're called gymnosperms. that's a good keyword

for eukaryotic cilia and flagella, they have the same 9+2 microtubule structure, and the basal body structure of 9X3. they use the same protein motors. bacterial ones are different, however. They have different basal bodies consisting of protein rings that act like anchors. Then there's the hook, an...
