Carnivorous plants utilize that method of nutrient gathering primarily to harvest nitrogen, since animals are made of a lot of protein which breaks down to amino acids which are all nitrogen containing.

Carnivorous plants acquire nitrogen through their traps, but many acquire normal micronutrients through their roots as well. Just some cool facts: Flytraps are closely related to Sundews (Drosera) and the traps are just heavily modified versions of the more ancestral (but still crazy) “sticky traps” typical of the family. Also, if you’re ever bored, look into Bladderworts (Utricularia). If you think Venus Flytraps are crazy, the trapping mechanism on these will blow your mind! They do hold the title of the world’s fastest plant after all

For anyone wondering why our lungs couldn't extract oxygen out of blood while a baby's placenta can, baby's blood is made up of fetal hemoglobin, which has a higher affinity for oxygen when compared to regular hemoglobin, so it is able to pull oxygen out of the maternal blood. There would probably also be issues with surface area in the lung

about venus fly traps: they will actually die if you put them in soil with any nutrients, add any water that isnt distilled or rain water, or even put them in a pot that can leach anything into their water. their roots exist (from what i can remember) really just to hold them into the ground and suck up water. theyre used to North Carolina's subtropical wetlands, where the ground they're in is being soaked and resoaked to the point where the soil has very little minerals and nutrients. they have adapted slowly to their native environment (which btw is only within a 75 mile radius of Wilmington North Carolina) which is why theyre carnivorous in the first place, the only sustainable way for them to gather nutrients is to catch bugs. so they do, and they have done for so long, that they are no longer built to do so through other means. they also go through winter dormancy!

@kayden8093 3 месяца назад

a single venus fly trap head can reopen to catch something else after digesting prey but most of the time a head will die after it finishes digesting.

@kayden8093 3 месяца назад

the soil they do best in is 1 part peat or sphagnum moss, 1 part sand, and 1 part pearlite, all of which you should try to ask a store clerk to find the ones with as few additivesas possible. they pretty much never want to dry out completely, and want to be in as bright of indirect light as you can get them [unless it's fall/winter] put them in a well draining plastic pot with a tray, and bottom water from the tray with distilled water. allow water to sit in tray for up to three days, refill tray after its been empty with no water seeping out of the bottom of the pot for one day. I dint have great tips for winter dormancy as unfortunately all of my vft's have died during dormancy or as I was bringing them out of dormancy so I'm definitely doing something wrong there

Can confirm, your nail would grow straight out of your nail bed, regardless of where your nail bed is. When my finger was cut off at the distal phalange, a piece of nail bed survived into the scar tissue. Couple months later, I had a triangular shiv of nail growing straight out of the new tip of my finger.

Perfusionist here, ECMO can oxygenate and pump your blood for you for months actually. it's similar to cardiopulmonary bypass. Prior to cardiopulmonary bypass Dr Lilihei actually did connect a child to their parent in a procedure called "cross circulation" where the parent/donor would oxygenate and pump blood for the patient during surgery

Hey, fun note. Piss is blood but shit is also blood. A significant portion of poop is made up of old used-up red blood cells that your liver filters out. This is why even if you fast for a long time, you will still poop occasionally. :)

@Ferinex_666 3 месяца назад

Your fingers don't prune because your skin is absorbing water. They prune because it's an evolutionary advantage - the extra surface area on pruned fingers gives better grip on wet surfaces.

@SatanicJamnic 3 месяца назад

@tv-pp 3 месяца назад

Pruny fingers are an evolutionary trait to increase grip, not really absorption of water. People with dead nerves in their hands don't get pruny. I think.

@Telleryn 2 месяца назад

You'd probably have to filter out the blood cells, but other than that it might work, also I vaguely remember reading about our brains, that the reason we're born so helpless isn't a birth canal to head size issue (the upper limit on the size of the birth canal before it starts interfering with things like walking is higher than we once thought), but because our brains have evolved to require input and interaction as in important part of development, and it's hard to do that from inside a person (there was a horrendous experiment where babies were deprived of human interaction during critical parts of development to see if humans had a 'natural state' free of the influence of others - it didn't end well)

@kennysproat3747 3 месяца назад

The Northern lights glow because of the charged particles hitting the atmosphere. AFAIK, the main reason (aside from coagulation) fish can't survive in blood is that blood cells bind to oxygen and fish gills can only extract dissolved oxygen from a fluid.

@Ferinex_666 2 месяца назад

Humans evolved to have shorter gestational periods than most other mammals because we rely on parental and communal protection as babies. So, to reduce the chance of maternal death and increase the chance of birth, we're born with a level of development far behind that of other animals. If humans didn't give birth until their offspring had reached that same level of development, women would be pregnant for like two years.

@edd-boy3696 3 месяца назад

"How do [the auroras [the northern and southern lights]] glow" hello mister william osman you might remember this lesson from high school chemistry (feel free more commenters to correct me where im wrong) as those charged particles that allen mentioned hit the atmosphere, they are absorbed by the atmosphere itself. as the energy is absorbed, some of the electrons of the atom enter a higher energy state. think of it as the electrons orbiting (ignoring quantum bs for a minute) higher up around the nucleus. as the electron loses it's energy it falls back down to it's normal orbit. this happens instantaneously. as the electron drops to its lower orbit it releases the energy as a light photon. that light photon has its wavelength proportional to the amount of energy that was expelled by dropping to the lower orbit! The photon of light's color corresponds to the wavelength :)

@MrHeroicDemon 3 месяца назад

Yes, you can breathe most liquids into your lungs, issues are drowning happens with, 1 not enough oxygen in the brain, 2, shock, because humans are used to breathing in air. So your body would react oddly to different pressure. Diaphragmatic breathing would be altered. So keeping a comatose person alive, we have a couple machines put in place. Any other ways to keep oxygen levels normal.

linking topics together, what happens if someones DNA gets completely wiped and then you link their circulatory system with a compatible partner. Rather than a single transfusion a constant stream of new cells and some healthy organs filtering out the decay. If it somehow helped them live, would their DNA end up matching the DNA of the donor? would they over time transform into the donor?

@ecchikitty1395 3 месяца назад

(17:53) Getting 'pruney' in water is not an indication of having absorbed water. Your body does it when it detects being wet, in theory to get a better grip on wet surfaces. If your fingers have nerve damage, they will never prune up.

RE: animals walking right away, but humans can't It's not because animals are stupider/less complex, humans are simply born earlier in the development cycle than most animals because we give birth to big headed babies(compared to our size) and walk upright(which limits the hip size). Humans thus have to develop outside the womb for the last part of their development to get to the point they can crawl(which is more similar to deer walking since keeping upright is hard and our brains do a lot of adjustments when we walk that we aren't even aware of).

How Northern lights work is how LED’s work. If you find a video explaining that, that’s going to help you understand auroras much better. But unlike earth’s surface where we need solid materials to conduct the electricity, there’s so much electricity and radiation in the upper atmosphere where the aurora is that it all conducts through gases (and would be fatal to humans).
