| Are a butterfly and a caterpillar the same animal genetically? Posted: 13 Jul 2019 02:17 PM PDT How can an organism achieve such a drastic transformation using the same genome? Does a caterpillar's DNA undergo a rewrite when it metamorphoses? Is there some sort of inherent gene editing going on? [link] [comments]  |

| Posted: 14 Jul 2019 12:35 AM PDT Hello, My friends and I were debating this the other day. For me, there is no way that scissors could break the carbon carbon bonds. I think it is more likely that the pressure of the scissors is enough to pull the molecules appart Can someone help us on this matter? I couldn't fine anything on the internet. Meh, should have read the title before posting. Sorry about that [link] [comments]  |
| Posted: 13 Jul 2019 11:58 PM PDT Also, aside from the obvious fact that being able to digest many different kinds of foods means that we can survive shortages of a various food, does our strategy offer any other advantages? [link] [comments]  |

| What is the name of the first species? Posted: 13 Jul 2019 07:47 PM PDT I've tried to google the name of the first organism, but I just get Bacteria or Prokaryotes. What is the earliest classified species of life? [link] [comments]  |
| Posted: 14 Jul 2019 01:01 AM PDT To simplify the question I'm going to say we burn fat in layers like an onion, which I don't think is true. If I eat nothing but an abundance of healthy balanced foods ( enough to gain a layer fat which we'll call "good fat" ) then for a period eat nothing but Cheetos ( for my next layer of fat which we'll call "bad fat") Is the Cheeto layer less nutrient/ does it provide less energy than the fats made from healthy foods? Or is fat just fat and there is no good or bad? If we take away the layer burning idea and fat is burned more randomly, could it be we get little spurts of energy because our body randomly burned a bit of "good fat"? [link] [comments]  |
| Posted: 14 Jul 2019 12:56 AM PDT People with Type 2 Diabetes have an impaired ability of angiogenesis due to high blood glucose posing toxicity towards endothelial cells. Since angiogenesis is required for cancer metastasis, due Type 2 Diabetes patients have a lower risk of cancer? [link] [comments]  |

| Why is strep throat, caused by a commensal bacteria, contagious? Posted: 14 Jul 2019 12:42 AM PDT I went to my doctor and was diagnosed with strep throat. I was told that after 24 hrs of antibiotics my strep throat won't be contagious. I was also told that strep is commensal and opportunistic, and a secondary infection to my viral cold. I had a break in the barrier that normally keeps the Group A strep from accessing nutrients, but the changes in conditions caused by my cold meant that my normally chill bacteria started growing out of control. I know contagiousness is due to active bacteria being spread and causing infection in others, but what I don't get is that everyone has Streptococcus pyogenes living commensally in/on them, so how can it be "spread"? It's only causing an infection in me because my barriers broke down, but surely for someone else who's healthy and hasn't had a cold that weakens their innate protection it wouldn't be an issue? TL;DR why is strep "contagious" when everyone has it anyway? [link] [comments]  |

| Do all planets rotate around the same plane/ axis ? Posted: 13 Jul 2019 04:50 PM PDT This is hard for me to formulate but bare with me. So since outer space is a 3 dimensional space. Consider you're at the north pole of the sun looking to the sky, do all planets rotate at a single level as if they are aligned. is there even the slightest off possibilty that all planets align causing a solar system eclipse of some sorts ? Or do they rotate on different axis and planes? [link] [comments]  |

| Why does oil work so well at removing stickers? Posted: 13 Jul 2019 03:45 PM PDT So i've noticed that oil works really well at removing stickers and I'm really curious as to how the oil works against the paper and the adhesive. [link] [comments]  |

| How did large theropod dinosaurs mate? Posted: 13 Jul 2019 10:44 AM PDT Large theropod dinosaurs like allosaurus and tyrannosaurus had large, long, top-heavy bodies with stiff muscular tails? How would they find a correct mating position? [link] [comments]  |
| Would decompression have any affect on stopping or slowing a projectile in space? Posted: 13 Jul 2019 06:16 AM PDT What prompted this question is the scene in Star Trek Into Darkness where Khan and Kirk perform a space jump first by being depressurized and pushed into the vacuum of space, and then guiding themselves to an entry port on the enemy ship... that also depressurizes when it opens. Wouldn't this exert the same or similar amount of force? If yes, would that not stop them instantly at the point of entry? Would that sudden halt kill them, or does decompression disperse air quickly enough that any incoming projectile (human or otherwise) has more than enough mass to pass right through? Are aerodynamics even at play in space? Hope that makes sense. I'm sure there are variations depending on the size of the projectile and amount of pressure on either end, but I was curious about the physics here - both if the depressurization is equal or unequal.

| How do animal species near extinction make comebacks, like the rhinos making 1000% increase? Posted: 13 Jul 2019 10:37 AM PDT I saw on a program years ago that females should birth as many offspring from as many different males as possible. How does that protect the inbreeding problem? Aren't all mammals subject to the same genetic restrictions regarding birth defects? [link] [comments]  |
