| How can adrenaline slow your bleeding? Posted: 08 Apr 2021 03:50 PM PDT So I recently just found out that adrenaline can actually be injected into you. I thought it was just something your body produced, and apparently it can be used to slow your bleeding. So with that knowledge here is my question. If adrenaline makes your heart pump faster then why or how does it slow down bleeding if your heart is pumping more blood? [link] [comments]  |

| When batteries start to lose voltage do they produce less current? Posted: 08 Apr 2021 04:09 PM PDT So when a battery starts to lose voltage does it produce less current and therefore the object that is connecting to it can produce less power from it. If so is there like a minimum amount of power objects can run on and when this threshold is not longer obtainable the battery is considered dead? [link] [comments]  |
| Posted: 08 Apr 2021 10:01 AM PDT I've recently been reading on energy band gaps, and I was curious as to how the "sea of electrons" understanding of delocalized electrons in metals translate to the valence band gaps of metals being half-filled. For n-type semiconductors, an excess electron can move more freely. Since n-type doped semiconductors have more than one excess electron, due it having more than one impurity atom, how is this different from the "sea of electrons" in metals? Why does it lead to different band gap representations? Edit: changed p-type to n-type. [link] [comments]  |
| Lifespan of Norovirus on Surfaces? Posted: 08 Apr 2021 07:27 PM PDT Apologies if I haven't picked the correct sub for this question! There seems to be conflicting opinions on the longevity of Norovirus on surfaces - some websites say up to 2 weeks, others say up to a month, others say even more. Outside of perfectly still water and laboratory controlled conditions, is there an estimate on this for general household environments? Long story short - I have moved in to a brand new share house. Within days one of the tenants has contracted gastro. Luckily I was away for work so I've been gone for 2 and a half weeks since then, and am about to return. Everybody is fine but I am a pretty severe germaphobe, I hardly know these people and I really don't want to come across as over the top if I rock up and get the bleach out close to 3 weeks after it's a distant memory for everybody else. I'll be fine being careful of washing my hands etc. however for my own peace of mind I'd love to know how long it is before I can assume it's gone and stop having to be so vigilant Thank you!

| How does a dam change the flow rate of water? Posted: 08 Apr 2021 01:00 PM PDT Hi all Water is a continuous problem for a lot of countries. Dams being built often is a cause of international conflict (eg. On Mekong and Nile river). There is the obvious problem of people being displaced and the ecological impact, but the acces of water is also reguraly mentioned. My question is how a dam has an impact on the flow rate. In my mind, when the dam fills up, the flow rate downstream will return to normal once the reservoir/lake has filled up. Essentially conserving the status quo of flow in/out. How or where am i wrong in my thought process? Or is this a misinterpretation in media? Obligatory "not a native speaker" I also wasn't sure to put this at earth sciences or engineering, i hope this post was tagged correctly? [link] [comments]  |
| Is required delta-v to reach mars polar and equatorial landing sites different? Posted: 08 Apr 2021 12:17 PM PDT My intuition tells me it is harder to land on pole vs equator. But hence I can't find definitive confirmation (also, I don't have skills to make calculations...), maybe I'm wrong on this. Or maybe the difference is totally insignificant. So: does spacecraft need significantly more delta-v to land on martian pole? I am trying to understand if, lets say, 1000 kg of cargo needs exactly the same amount of fuel to safely land on poles vs equator. And if not, whether the difference is more like 0,5% (rather insignificant) or closer to 5% (significant). [link] [comments]  |

| Posted: 08 Apr 2021 07:51 PM PDT Q2 - The virus's Spike protein binds to the ACE2 receptor, which in normal operation is bound to by angiotensin II. Could the immune system response to the Spike protein lead to a response against angiotensin II, and if so, what would be the ramifications of this? [link] [comments]  |
| Posted: 08 Apr 2021 09:17 AM PDT I've been reading a lot about the satiation defense, and how the 17 or 13 years also cause the predators to not have a memory/knowledge of the brood event thus not waiting for the brood to occur.. Just curios about the brood event on other parts of the biome. Just seems that something else should have aligned with the broods. [link] [comments]  |
| Posted: 08 Apr 2021 03:42 PM PDT I'm really unsure about which flare to use so I'll use human body since it relates to that. [link] [comments]  |
| Posted: 08 Apr 2021 06:01 AM PDT Vaccines and allergy shots seem nearly equivalent, both inject some small amount of a harmless protein to introduce it to your immune system. Why do allergy shots train your immune system to stop attacking that protein and vaccines train your body to launch a larger immune response to that protein? I know that mRNA vaccines inject the instructions and your cells build the proteins and that conventional vaccines inject parts of a virus or weakened virus, but I don't think that accounts for the difference.

| Cooking meat in a stew makes it go soft. Microwaving the same stew makes it chewy again. Why? Posted: 08 Apr 2021 04:13 AM PDT In both cases, the meat is being more or less being 'boiled'. Why does one lead to yummy goodness and the other to chewy disappointment? [link] [comments]  |
| Does baby-wearing enhance the child's ability to regulate their stress responses and/or self-soothe? Posted: 07 Apr 2021 11:58 PM PDT We know that carrying or wearing an infant activates their parasympathetic nervous system, thus allowing them to calm down and/or sleep. Some books promote the theory that regularly wearing the baby helps her to develop the parasympathetic nervous system, thereby eventually allowing her to "self-soothe" more efficiently. How scientifically valid is this idea? Can the nervous system be trained in this manner, especially in infants? [link] [comments]  |
| Posted: 08 Apr 2021 05:45 AM PDT Just what the title says. Would such a powerful, blinding light disrupt the normal biochemistry of the brain in any way. Would you have problems with vision and or changed thinking? [link] [comments]  |
| Posted: 07 Apr 2021 10:32 PM PDT Do they still get them and it just doesn't bother them? Are the cells in their mouth just working overtime to push the splinters out? [link] [comments]  |
| There's one single answer of how is the mechanism of how flagella work or there are several? Posted: 08 Apr 2021 05:47 AM PDT In my research to find out the mechanism that makes flagella move, as I understand it, It seems that there are many explanations for this phenomenon. I understand that flagella may vary along with organisms and this would interfere with the "one explanation for the mechanism", but does science know for sure how this works or this the molecular explanation of this is still in progress? I see some explanation about the sliding in the microtubules in the axomena is responsible for the flagellar movement, but it seems to me that this explanation is still on debate.
