Ah, good point. That is most obvious. Blood pressure is unrqual and too high in the head in 0g, too low in the bottom extremeties. I was imagining intracellula

Ah, good point. That is most obvious. Blood pressure is unrqual and too high in the head in 0g, too low in the bottom extremeties. I was imagining intracellular processes being effected. There are such processes in plants that are usually used for steering. In animals cells, if such thing exists, it may be minor efficiency changes in processes that add up to diverging from homeostasis.
