Narvin: first of all, awesome question dude! Though am sure the life forms that we know of can not be synthesisng new atoms in its true sense, we could think of it in a bit different way... Chris: arent the techitium era atoms created made from preexisting ones? I mean consider this along with...

Am a I MBBS student with a love for genetics, evolution and immunology!

This along with exposure theory seems like the most likely explanation! Thank you!

Well, the prokaryotes still have a nucleoid region. Yeah the cell will have a comparitively short lifespan but they can say live something close to what the RBCs do (120 days) any such cells? Thank you for your other answers! :thumbup:

1.How did the nucleus evolve? 2.What are the pointers indicating the evolution of eukaryotes from the same branch as archea? 3.Obligate anaerobes, what is the end products? Does it include molecular oxygen? What is it in case of facultative anaerobes? Is there any organism that uses a...

But think of in terms of exposure time... we usually spend a few minutss to eat and a few hours to digest... so won't the amount of time that intestinal peyers patches and other regions, say the stomach, stay exposed to the food substance be greater? Hence wouldn't it require better drainage...

Why the tongue though small has such extensive lymphatic drainage? Is it just developmental relation? Or is it that tongue has high exposure to immunogenic substances(which I feel is not the case)?

In membrane potential determination of a cell, the Goldman Hodgkin Katz equation says the contribution of an ion to diffusion potential is dependent on its membrane permeability. So in case an ion, one that has a zero permeability, is present outside the cell, using the equation , one will get...
