The patience and time these people invested in their art is not from this time. Diatom art as way to out your love and fascination for the microcosmos who would have thought that.

@Chris-op7yt 3 года назад
"Hunting is the practice of seeking, pursuing and capturing or killing"..of prey. It's a useful but broad term, that can be split into active and passive categoties of hunting, and then split into more specific kinds, like trap hunting, which the heliozoans have in common with spiders, for instance. Then there's trap-door spiders and many different uses of web. It's not that different spinning a web to trap prey, to growing appendages that do similar job. It might look funny/different but not to dissimilar to a spider hunting with a web etc.

How much energy do the heliozoa use to rebuild their microtubules? Are they an actively maintained structure that the organism has to aggressively invest resources in, or are they a stable low-energy state that mostly automatically reforms on its own once conditions are favourable for it?

Almost as if the increasing density of science makes him excited again!

People with ADHD actually usually speak at a faster pace due to their racing minds and how excited they get when they actually care about something enough to talk about it, so I'd say him going faster makes him more ADHD-like, rather than less, haha!

It seems that one end or the other of these microtubules that make up the "backbone" of the axopodia can be disassembled/eroded at will. Similar microtubules are assembled and disassembled inside your own cells, to move things around (like chromosomes during mitosis). (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5rqbmLiSkpk.html for instance)

@leejuicy
@leejuicy 3 года назад
@@ericpowell96 1. many MT-associated proteins and MT-modifying enzymes, which are central modulators in orch-or theory, are often dispensable for neuronal function. A good example is tubulin acetyltransferase MEC-17, where its loss-of-function phenotypes are limited to mechanosensation, despite acetylated tubulin being the predominant form of axonal MTs. Similarly, loss of many MAPs don't show overt behavioral phenotypes in model organisms. 2. Computer simulations of C elegans brain, the only animal so far to have every synaptic connections mapped, faithfully recapitulates its behavior. This simulation does not take account of any quantum effects, strongly arguing that quantum effects are unnecessary for the function of C elegans brain. Structures of MT and neurons are largely conserved between C elegans and humans, suggesting that qunatum effects are unlikely to play a central role in human behavior.
