| How much protein per 100g of human muscle? Posted: 25 Sep 2019 01:31 AM PDT Hey everyone, I'm wondering this because I saw chicken is about 26-33g of protein per 100g and chicken breast is just muscle, which had me wondering what would it be in a human? I am aware it would vary from muscle to muscle but can't find any data online. I promise I'm not a cannibal. [link] [comments]  |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 25 Sep 2019 08:08 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |

| Posted: 25 Sep 2019 05:13 AM PDT Earth's atmosphere contains hardly any H, it's mostly O and N. My suspicion is that the H comes from water, but that takes a lot of energy! [link] [comments]  |
| Could a rogue planet orbit a star? Posted: 25 Sep 2019 02:35 AM PDT For example say a rogue planet came into a random solar system, could the planet get caught into the stars gravitational pull and become a regular planet and not a rogue one anymore? This is all assuming rogue planets are floating through space cause I'm not totally sure about that. [link] [comments]  |
| Does someone's own spoken accent also have the highest listening comprehension? Posted: 25 Sep 2019 06:59 AM PDT This question came up while discussing listening to audio with the speed increased to x2-3 original speed and the general comprehension of different accents when speeded up. I myself find it easier to listen to speech closer to RP (Received Pronunciation) than to my own accent. However I likely understand my own accent better than the average English speaker. So my question is, how common is it for people to have higher listening comprehension on accents which aren't their own spoken accent? Why does this happen? Is this effect something which is studied or just a weird outlier? [link] [comments]  |
| Is there a way to measure a gene's dominance? Posted: 25 Sep 2019 06:40 AM PDT So I was thinking about the very basics of genetics I learned at school and stumbled upon this thought, despite not caring much for biology class not understanding this concept still bothers me due to my disliking of randomness. Can a gene's dominance somehow be determined without specific testing? My guess would be this, if gene A is dominant over gene B and gene B is dominant over gene C can I assume gene A is also dominant over gene C? so gene A could be assigned a dominance level of 3, B assigned 2 and C assigned 1. Can someone please disprove this for me? Alternatively maybe genes could be assigned classes, with class A being dominant over class B, class B dominant over class C, class C dominant over class A and D, and class D dominant over class B, so you can assume that if a gene is dominant over class A it must belong to class C hence also dominant over class D. Although this one might be practically impossible to prove due to a potentially infinite amount of classes, so if a gene is dominant over class A it might still not be dominant over class D and instead belong to a new class E. Is there a more likely theory? perhaps based on experimentation rather then thoughts some kid had while walking his dog? or is this subject rather unexplored and I can't hope for an answer any time soon? Thanks in advance and sorry if I'm overlooking something and the answer is actually obvious or anything of the sorts. [link] [comments]  |

| Is a zero order relationship even possible? Posted: 25 Sep 2019 04:44 AM PDT In school I studied that one of the reactants in a chemical reaction can have a zero order relation to the rate of reaction i.e its concentration does not affect the rate. However, the particle theory states that higher concentration leads to higher no. of atoms per cm^3, therefore a higher number of successful collisions. So, according to the particle theory no reactant can have a zero order relation. Then how does the reaction kinetic theory propose a zero order reaction? [link] [comments]  |
| Which continents, or areas, are the best for finding fossil records, and why is that so? Posted: 25 Sep 2019 03:17 AM PDT So apparently there are no land fossil records from when earth only had one huge continent called Pangaea? Also if I recall most fossil records come from China or Africa(could be wrong), so I wonder why fossils have survived much better in those areas. Were other continents more unlivable? or did they go through larger drastic geological changes which destroyed remains? [link] [comments]  |
| Why do you think the phanerozoic eon has more divisions and dates than the archean eon? Posted: 25 Sep 2019 03:17 AM PDT |
| Posted: 24 Sep 2019 11:07 PM PDT To my (potentially incorrect) understanding, thermostable proteins have a high rate of alpha-helices and have smaller loops/turns; thus, the proteins are more compact and the "backbone" is less exposed to potentially damaging temperatures. Would hydrophobic interactions be the key player in holding the helix/stucture together? Would it be additional H-bonding and attractive forces between the side chains? I appreciate any insight someone might have! [link] [comments]  |
| CDC Quarantine, Decontamination and Sterilisation Procedures? Posted: 24 Sep 2019 10:42 PM PDT Now I'm certain that any who can answer likely can't say everything but, there is something about the Centers for Disease Control and Prevention (CDC) I have always wondered about. In a hypothetical worst case accident scenario in a laboratory, what sort of Decontamination and Sterilisation Procedures does/would the CDC institute to prevent deadly pathogens from endangering the public? Do they have lock down and incinerate procedures like in movies and TV? [link] [comments]  |

| What does "Carrier" and "Carrier Free" mean when transporting radioactive solutions? Posted: 25 Sep 2019 02:03 AM PDT In my work regarding ionizing radiation and radio-nuclides I noticed that in the majority of cases, radioactive solutions are not transported in their pure form, but they are mixed with another material named a "Carrier". Can some one please elaborate what is the purpose of this carrier substance and why is it needed? The only explanation I can come up with is due to physical limitations. For example, if I want to transport 25 [mCi] of Iodine 125, that would translate into around 1.47 10^-6 [g] which means it would require an extremely small container that, I guess, would be very difficult to produce, so the carrier substance provides some kind of a "buffer" without altering the activity of I-125.

| Posted: 25 Sep 2019 12:56 AM PDT Animals are capable of storing energy as fat, is it possible to feed a spider or ant until it's fat. Bees wax is fat but is it possible to store so much of it, it would not be able to fly? [link] [comments]  |
| Why not "hot air balloon" rockets up before "lift off"? Posted: 24 Sep 2019 01:51 PM PDT Is it possible to lift up rockets to the upper atmospheres before using rocket fuel? Or is there just too many variables you can't control from having "lift off" mid air and too many variables you need to align/aligning to do this kind of thing? Ignoring the variables, and it works, does this save a lot of money? Also I'm not really a scientist/engineer or even a student in any field of science/maths, but I do have a, let's say a hobbyist level understanding of things/intelligence since (forgive me) i graduated not on my peak, and have been stagnant eversince. So have mercy on me with the explanations [link] [comments]  |
