| Posted: 04 Apr 2019 04:58 AM PDT Since stomach acid is strong enough to dissolve metal, what would happen if the acid from inside your stomach got out? Would it do the same to other organs? [link] [comments]  |
| Can bacteria take over cells like viruses do? Posted: 04 Apr 2019 04:27 AM PDT I've been taught that some viruses 'take over' cells, change what they do and use them to spread. Can bacteria do something similar? Of so, what is this process called? If not, why? [link] [comments]  |

| How can you take a picture of a black hole? Posted: 04 Apr 2019 12:11 AM PDT A picture of a black hole will be revealed next week. From my understanding, a black hole absorbs all light due to its gravitational field. We can only see something when light is reflected off it. With these both assumptions in mind, how can a picture be taken of a black hole? [link] [comments]  |

| Do animals have a sense of (Musical) rhythm? Posted: 03 Apr 2019 08:44 PM PDT Well, that. I know that we (Humans) can feel rhythm (Though I don't specifically know why either), and we react to it. But do animals feel the same? Or they hate it because it interferes with their senses, like when you suddenly cover someone's eyes? [link] [comments]  |
| Benefits and, or disadvantages of hemocyanin oxygen transport rather than hemoglobin? Posted: 03 Apr 2019 07:40 PM PDT Is one all around more efficient than the other, or only under certain situations is one more efficient? Does the difference in copper vs iron provide any sort of bacterial or viral resistance? Or possibly lower chance of infection due to open wounds? [link] [comments]  |
| Posted: 04 Apr 2019 01:29 AM PDT I'm currently in chemistry in high school and my teacher stated that it's quite debated if diluting something in water is considered a chemical or a physical change because of how the particles are seperated from one another but the compounds themselves don't actually change. I'm mostly wondering if my teacher is out of the loop and if there's an actual answer to what it is [link] [comments]  |
| Posted: 03 Apr 2019 08:19 PM PDT I have read that (Keyhole Limpet Hemocyanin) is used to help treat prostate and bladder cancers as it stimulates the immune system. But do the organisms that use it naturally benefit from this? [link] [comments]  |
| What does re normalization means in simple terms with context of Quantum field theories ? Posted: 04 Apr 2019 04:40 AM PDT Why are we able to re normalize QFT for Weak, Strong, and electromagnetic interactions, but not gravitational interactions? [link] [comments]  |
| What are some interesting examples of humans influencing the evolution of a species? Posted: 03 Apr 2019 12:15 PM PDT Most people who've taken a basic course in biology know about the speckled moths that turned black during the industrial revolution due to pollution. I want to know what other examples there are of humans influencing the evolution of other species. The more interesting or unexpected the better. [link] [comments]  |
| Is there a lower limit or smallest unit of time? Posted: 04 Apr 2019 12:09 AM PDT I'm sorry if this is a stupid question. I have a high school education and never took any math higher than algebra, save some stuff I've taught myself for the purpose of audio synthesis because I read a lot. So I've been reading about superfluid He4 and how what I will call "practical absolute zero" (i don't know the real term) is higher than 0 kelvin, and that this is due to a baseline ambient excitation that occurs as a sort of prerequisite for physical existence. I was also reading that states above that are quantized. I also read the inevitable connection to the Heisenberg uncertainty principle, which has to do with precisely measuring velocity and position. The only way that makes sense to me would be that a particle's position is only accurate for an instant. You can't measure velocity in an instant, that much is apparent because there needs to be a duration of movement factored in to measure, therefore it can probably only be approximated. You can measure position, except for the fact that the particle is moving, so again, to measure where it is in this hypothetical "instant" would be difficult to do precisely. A lot of this seemed to be revolving around this "point" in time that occurs instantaneously, which I am having trouble comprehending. So it got me wondering, is there a duration that is the absolute minimum that time can be broken down into? We measure time with a system of quantized integers, but is it possible that time itself is actually quantized? If that's the case, is space also quantized? Is everything operating on a grid of values that can be represented by a cardinal set of natural numbers? Is aleph 0 the only real infinity in physics? I'm confused, I hope this question doesn't sound as dumb to you as it does to me. [link] [comments]  |

| Are space telescopes analogue or digital based? Posted: 04 Apr 2019 03:30 AM PDT I have this hunch that analogue contains more information due to the film medium, although I may be wrong, that's why I have come to your doors! [link] [comments]  |
| How do plants in early development orient themselves in zero gravity? Posted: 03 Apr 2019 02:04 PM PDT I know in normal development that plants orient up from down through the vacoule moving to the bottom of the endosperm(via gravity) which provides polarity. My curiosity is in how do the plants grown on the ISS orient themselves in the lack of gravity? [link] [comments]  |
| If a person is brain dead, can their body heal wounds or broken bones? Posted: 03 Apr 2019 04:15 PM PDT |
| Posted: 03 Apr 2019 08:59 AM PDT This might be stupid question, but it's something I've been thinking about. I can't wrap my head around how there is any pressure at the center of something if there's no gravitation force there. [link] [comments]  |
| Why do some vaccines hurt more than others despite all being administered the same way? Posted: 03 Apr 2019 01:33 PM PDT I got the influenza vaccine earlier this year and it didn't hurt at all, but I just got the second round of the HPV vaccine and my arm is extremely tender and sore. Why is there a difference between the two when they're both administered in the same way and in the same place? [link] [comments]  |

| In regards to sunscreen and its effectiveness over time. How is it "used up"? Posted: 03 Apr 2019 02:02 PM PDT They say that you need to reapply sunscreen every two hours but is that duration dependent on how much the sun's photons reacts with the sunscreen on your skin or is it simply that the sunscreen loses its effectiveness the longer it is on your skin?
