| How does the structure of cat skin and connective tissue differ from human skin? (I.e. what makes it so I can pull my cat’s skin away from his body?) Posted: 02 Apr 2022 05:02 AM PDT I know the theorized adaptive purpose of this (added flexibility for movement, loose skin, especially on the primordial pouch, helps protect internal organs in fights), so my question is not about that. But how does cat skin do that? Like, I can't grab my skin and pull it away from my insides like you can with a cat- it's very firmly attached. So how does cat skin (and lots of other mammals) differ from mine to allow it to do that? Do they have different proportions or structures of collagen and elastin? Are the superficial fascia connected to different points than in humans? submitted by /u/pdxpython [link] [comments] |

| How does a contraceptive injection work over multiple months? Posted: 01 Apr 2022 03:44 PM PDT I am trying to find information about how contraceptive injections work, but all explanations I've found so far basically say: "insert progestogen, ???, profit". Where does it go all those three months? Is it just hanging around in your blood stream? Or at the injection site? How does this last for 3 months when a pill needs to be taken every single day? submitted by /u/Hedanito [link] [comments] |

| Why was the hunan genome mapping stuck at 92% for so many years? Posted: 01 Apr 2022 09:31 AM PDT I recently read some titles about the successful mapping of the last 8% and was wondering about what i wrote in the title. Bonus question: is this data available to the public? submitted by /u/eyebrow911 [link] [comments] |

| Do larger hearts require more, less or the same amount of electricity as a human sized heart to be restarted? Posted: 02 Apr 2022 01:19 AM PDT I'm asking this as I'm writing a story and I just got the question in my head. In my story there are dragons, and if their rider passes, so too do they. So, if the rider's heart stops, so too would theirs. I know a human heart can be restarted, any heart could really, but I was wondering if more electricity would be needed to try to restart the heart the larger the animal is, and thus the heart is. I tried looking it up, and will keep trying, but so far not having much luck. I don't know if the Medicine or Biology flair fits better here since it's regarding both in a way. submitted by /u/Nightengate32 [link] [comments] |
| Is the amount of salt in the ocean increasing? Why or why not? Posted: 01 Apr 2022 04:06 PM PDT Is the salinity in the ocean changing? If so, why? How does the salt or other minerals behave and migrant as part of the water cycle? submitted by /u/Carson_Harrington [link] [comments] |
| Does space affect the metabolizing of medications? Posted: 01 Apr 2022 08:40 AM PDT Background: so the other day I read about how moon dust is an allergen, to which someone made a meme about needing an epi-pen. Which got me thinking that an epi-pen is probably over kill. So what about a Zertec or a benedryl? Actual questions: since most medication dosing instructions are based on a combination of averages based on weights, ages, and the body's ability to metabolize the medication itself, how would space affect the breakdown of meds such as benedryl? Since space changes everything from water distribution to proteins created is there a significant change? submitted by /u/stubs1101 [link] [comments] |
| Is there something in our body that gives a clue about our [species, not individual] approximate lifespan? Posted: 01 Apr 2022 08:15 AM PDT For instance, if an alien species abduct a single human, would they be able to find out that we're supposed to live a maximum of 80 to 100 years? And if it's possible, how young could that person be so that prediction is still accurate enough? (All of this using known, earth science, obviously) submitted by /u/cimocw [link] [comments] |
| Can photon colliding produce non-elementary particles? Posted: 01 Apr 2022 05:55 AM PDT Photon colliding can produce an electron and a positron, a quark and anti-quark,... etc. However, can it produce non-elementary particles like protons and anti-protons? If so, how does this process happen, like do they produce quarks and then they get combined or do protorons just get born instantly? Thanks! submitted by /u/vizex9 [link] [comments] |
| Why are V series nerve agents known to cause a flaccid paralysis while G series agents cause a firm paralysis when both are AChE inhibitors which use similar mechanisms? Posted: 01 Apr 2022 08:31 AM PDT Perhaps I'm missing something but in material I can find G series chemical weapons like Sarin, Tabun, and Saman are described as causing a firm paralysis as a result of the buildup of ACh following the inhibition of AChE. V series nerve agents like VX however are described as having the same initial symptoms of muscle spasms and convulsions but then afterward apparently result in a flaccid paralysis as the affected muscarinic and nicotinic ACh receptors become fatigued. What causes one to behave so differently from the other when they both seem to operate via the same mechanism? submitted by /u/quadrapod [link] [comments] |
| Is there a connection between our moon and Earth's plate tectonics? Posted: 01 Apr 2022 08:17 AM PDT I was just looking at the river near my house and noticed it was high tide which randomly got me thinking; Earth has the largest known moon when compared to its parent planets mass and earth is also the only planet we know to have continental plates. Tides are a result of the the moon's gravity stretching Earth's surface water into two bulges on either side of the planet. So my question is, could the moon be the reason for our planets continental plates Similar to say how the crust of Europa is basically shattered from Jupiter's tidal effects but on a much less intense scale.. if not, then what does give our planet it's plate structure, and is there any evidence that having tides, a large satellite, and/or continental plates is necessary for the stability needed for life to develop? tldr; Could the moon be the reason for our planets continental plates if not, then what does give our planet it's plate structure submitted by /u/Streetlight37 [link] [comments] |
