If humans did not burn fossil fuels and return some CO2 into the atmosphere, would the Earth reach a point of collapse where plants would not have any carbon to build with? Posted: 03 Aug 2020 12:20 AM PDT So I saw a video a while ago that went into details about how the Earth has been losing carbon in its atmosphere for some time now. As a result plants began to grow slower and smaller to sustain themselves. In recent years as a result of human activity it had been found that crops were growing quicker now due to the elevated levels of CO2 in the Atmosphere giving a greater abundance of building materials. Though, as a result to accelerated growth, vegetables were less nutritious. My question I guess is around what would happen if humans never burned fossil fuels and returned some of that Carbon into the atmosphere. Would we reach the point where plants would no longer be able to sustain themselves as they do now? Would fossil fuels just renew and trap more and more carbon out of the ecosystem and cause it to collapse at some point? submitted by /u/Dootduteeedo [link] [comments]

Why doesn’t a pot of boiling water evaporate instantly? Posted: 02 Aug 2020 10:56 PM PDT When you have a pot of boiling water on the stove at 100c (the boiling point of water), the water appears to only slowly evaporate. If the boiling point is defined as the temperature that liquids turn to gases, why doesn't it happen instantly? How can I have 100c liquid water at sea level, doesn't that mean the boiling point is higher in some instances? Thanks for any helpful replies. This has bugged me for awhile. submitted by /u/OneRisk1 [link] [comments]

How do short takeoff/landing planes work? Posted: 02 Aug 2020 07:16 AM PDT I'm really curious about the science behind planes that can take off and land with literally 6 feet of runway? Why do other planes need hundreds of yards/meters to take off where these planes can do it in like 6 feet/ 2 meters? submitted by /u/Tots795 [link] [comments]

Why does the cell membrane of human cells do not get dissolved with ethanol? Posted: 02 Aug 2020 06:57 AM PDT The other day I read a post were it was explained that ethanol is used to sterilize because it can dissolve viruses' and bacteria's lipidic membrane and denaturalize their proteins. So why when we put alcohol in a wound don't our cells get killed by the same mechanism that works for bacteria and viruses? submitted by /u/joalcuadrado [link] [comments]

Will my vaccine trial be used for other vaccines? Posted: 02 Aug 2020 07:56 AM PDT I'm taking part in a Covid vaccine trial that used proteins instead of dead virus. Can this be used later for ther vaccines? submitted by /u/We_Are_Chaos_555 [link] [comments]

In a Cu-Zn, H2SO4 battery, why do the electrons pushed off the Zn by SO4- not flow directly into the liquid phase to contact the H2+? Why do they flow through the wire to the Cu into the liquid phase instead? Posted: 02 Aug 2020 07:29 AM PDT Follow up question: Why does Zinc prefer to exist as ZnSO4 instead of Zn. Aren't both neutrally charged? Are the two electrons making the Zn neutral covalent in nature? submitted by /u/Gulrix [link] [comments]

is there a maximum tempature like there is a minimum tempature ( -273°C)? Posted: 02 Aug 2020 06:01 AM PDT I heard from my physics teacher that there is in fact an minimum tempature but not a maximum tempature. there is a minimum temperture because tempature is actually the pace of the atoms shaking, and the atoms at that tempature will then dont move anymore, and you cant move slower than not moving. but isnt it than possible that the maximum temperture is for the atoms to shake at lightspeed? submitted by /u/GijsHarbers2311 [link] [comments]

Evolution by randomness or necessity? Posted: 01 Aug 2020 08:48 PM PDT I always thought that Evolution is by selection. I mean, giraffes, for example, need to be taller to reach taller trees. So, next generation of giraffes will be taller than the old ones, but no by randomness, because they need it. Need to be taller to reach food. I was talking with a friend, and she says that occurs by randomness. That means, randomly, a giraffe did born with a taller neck, so the next generations of that giraffe did born with taller necks. But that sounds very unlikely to me. Just imagine, it is not just the neck. A giraffe needed a stronger heart to have the enough strength to push blood to the head, and needed better balance because gravity center is higher. It doesn't makes sense for me Evolution by randomness. Maybe a combination of both? I don't know. submitted by /u/sugardanni [link] [comments]

How much experience is required for the visual development of different animals? Posted: 01 Aug 2020 07:02 PM PDT Infant humans only have rudimentary visual perception at birth -- they can sense brightness and motion, and not much else. It takes a few months to develop more complex visual perception. What about other animals? Are their visual abilities innate? I guess this might be the case for simpler animals. What about more complex animals, such as mammals -- can any of them see well from birth, or do all mammals require a while to start seeing well? submitted by /u/Denziloe [link] [comments]

I've noticed several diseases that originate in birds to infect humans are unusually serious. Is this a pattern, or have I just been looking at bird diseases by random chance? If so, why? Posted: 01 Aug 2020 12:43 PM PDT The diseases in question are Botulinum/botulinism, which mostly affects migratory birds, West Nile and Eastern Equine Encephelitis, which both spread from birds to humans via mosquitoes, and of course avian influenza, which I think is more deadly than 'regular' (if such a thing exists) influenza. Is this a pattern that's been noticed by people who don't just listen to podcasts about horrible diseases, or is it a case of pattern recognition (learning about horrible diseases -> many mentioned come from birds -> are diseases from birds more horrible?) If so, why? submitted by /u/Mammoth-Corner [link] [comments]

Will melting ice displacement really make oceans rise?

How do CPU design engineers work with such massive yet tiny scales? Posted: 01 Aug 2020 10:57 AM PDT How do design engineers comprehend literally billions of transistors when redesigning chips. I assume the general format for a memory bus or a cache is kind of set, and most of the tech is making it smaller and more efficient, but they still must work in the transistor level of the circuitry, no? How does a person or group or company even begin to tackle a 10 billion unit problem? submitted by /u/SF2431 [link] [comments]

What is the relation between v , f and λ ? And does it change when we're talking about different waves (light , sound and water)? Posted: 01 Aug 2020 10:25 AM PDT Hello I'm in grade 10 and I'm doing the topic waves . What I'm struggling with is the relationship between v , f and λ. What I've been told is that v is directly proportional to λ so if the speed of a wave increases , the wavelength also increases and vice versa (provided f is constant) . I came across a question in which they were asking how the frequency of a water wave affects it's wavelength . So I searched it up and the answer was that frequency is inversely proportional to wavelength so if frequency increases , wavelength decreases and vice versa . But because wavelength and speed of a wave are directly proportional does that mean speed of a wave will also decrease if frequency is increased ? This doesn't make sense to me . Are the rules of v = fλ different when you're talking about different waves e.g light , water , sound . I'm struggling with this and don't know what to do and would really appreciate it if someone would explain the relation between these three quantities properly and how (if) they change when we're talking about different waves . Thank you ! submitted by /u/Nm_0672 [link] [comments]

At the challenger deep, would my body gets crushed to a thin film? Posted: 01 Aug 2020 05:40 AM PDT I understand that the pressure at those depths is immense.

If there is a column of water with bubbles, will the pressure at the bottom be different than it would be without bubbles? Posted: 01 Aug 2020 08:32 AM PDT So pressure depends on depth and density irrespective of the shape of the container. Water with bubbles in it would overall have a lower density but if the bubbles are not taken as part of the water and considered part of the 'container' then would the pressure change with depth stay the same as without bubbles? If so is there a size point where this no longer applies? Would tiny particles suspended in water with different density than the water have an effect on the pressure? submitted by /u/smus0025 [link] [comments]

Can people who have recovered from COVID-19 (or any virus) still spread the virus? Posted: 31 Jul 2020 10:53 AM PDT When someone has tested positive for antibodies, does that just mean they can't get sick again or they cannot spread it at all? For example, someone (Person A) who has already recovered from the virus comes into close contact with someone who has the virus (Person B). Can Person A somehow have the virus in their body and spread to others who have not been infected? I apologize if this is a dumb question.

Does constant low-level exposure to a virus keep our immune system primed? Posted: 31 Jul 2020 10:22 PM PDT I've read some early reports of antibodies for SARS-CoV-2 rapidly diminishing to almost undetectable levels in the majority of people who have had the virus after only three months. If someone who had the virus continues living or working in an environment where they were exposed to the virus daily (for example, frontline healthcare workers), would this regular exposure boost the antibody levels for these people and allow them to stay immune longer?

Theoretically, can any elements besides Hydrogen be used for a Thermonuclear fusion weapon? Posted: 31 Jul 2020 07:33 PM PDT I just watched a little overview about how thermonuclear weapons work and they basically state that Deuterium and Tritium are forced to collide because of great heat and pressure from a fission bomb. I've always know it was a staged reaction of sorts, but the thing that stuck out was that hydrogen made the most sense because there were fewer protons. Would heavier elements like Lithium or Sodium work in the same way given the right amount of heat or pressure? Or is it diminishing returns as something gets heavier? Or am I completely off base? submitted by /u/cosmonaut205 [link] [comments]

How do gauge bosons and vector bosons differ? Posted: 31 Jul 2020 06:47 PM PDT For context, I'm 17 years old and I'm about to start my last year of school. I know the fundamentals of the standard model, but I'm not familiar with the maths (I'm a Brit) associated with it. That's not to say I'm unwilling to try it – I'm always up for a challenge – but just something to bear in mind. All the articles I've seen either treat gauge and vector bosons as synonymous, or say stuff to the effect of all known gauge bosons are vector bosons which implies that it is possible for a gauge boson not to be a vector boson, suggesting they're different things, but they don't say how. Hence my question, how do gauge bosons and vector bosons differ? Thanks in advance for the help. submitted by /u/GibbNotGibbs [link] [comments]

Why so much attention goes to a possible vaccine but not for a treatment? Posted: 31 Jul 2020 08:20 PM PDT I mean, our hopes right now are the functionality of a vaccine but there's plenty of antibodies trials at the moment that doesn't have our attention. Why? if it's much faster to be approve by regulators and the efficacy also could be great. submitted by /u/josephreds [link] [comments]

How do the current recombinant viral SARS-CoV-2 vaccines induce immunity? Posted: 31 Jul 2020 05:59 AM PDT Pretty simple question, referring to the existing recombinant adenovirus vaccines in late stage trials (Oxford, Sinovac) and how they induce an immune response against the SARS-CoV-2 spike protein. I'm wondering about the genetic structure of the vector and the mechanism of immunogenicity. For example, is the protein part of the viral capsid? Is it a fusion protein with the capsid proteins similar to the approach used in phage display libraries? Is it purely genetic, and used as a delivery vector to induce expression once the genome is in a host cell? If it's the latter, how does this work for an inactivated virus like the one SinoVac is using? Also, if it's purely genetic, does it include a signal sequence for secretion, or purely rely upon presentation in the context of MHC-1? I would strongly appreciate any references, as I have read a number of press releases and publications which fail to clarify any of these details. submitted by /u/livaloq [link] [comments]
