How does the blood circulatory system adapt to amputations?

Posted: 17 Mar 2022 12:59 PM PDT

For example if your leg is amputated, all blood vessels going to the leg are now dead ends and the blood can't circulate normally. How does the blood coming from the heart get back to the heart if the connection via blood vessels is severed?

Were there any unique prehistoric types of marine environments?

Posted: 17 Mar 2022 08:08 PM PDT

Hello!

What I mean by this is: y'know how there are kelp forests, coral reefs, salt marshes, etc (marine environments)? Were there environments in prehistoric times which no longer exist?

What’s the difference between wrought iron and mild steel?

Posted: 17 Mar 2022 05:45 PM PDT

From what I can tell, they're both iron-carbon alloys with very little carbon.

I think maybe the difference is the presence of slag in wrought iron, but googling brings up some weird claims, like wrought iron actually being pure iron.

Thanks in advance!

If we were to theoretically point the James Webb Space Telescope straight towards Earth, how magnified of an image will we be able to see?

how slow can a plan fly?

Posted: 17 Mar 2022 04:03 AM PDT

A plan obviously needs to move in order to fly. What determines the minimum speed of a plane and how slow could we build a standard passenger airplane if we really wanted too?

Sidenote: I love this sub!

Edit: thanks for all the answers i guess. Reddit kepps sending me notifications, but the Post itself only shows one answer. As soon as i figure this bug out, you all will get upvotes and I'm already excited to learn from all of you!

How do humans think in absence of a learnt language?

Posted: 16 Mar 2022 08:17 PM PDT

Is there any seriously documented case of a feral child who learnt language as an adult to a degree of proficiency where he could explain and reflect on vivid memories about how their thought processes were in absence of a learnt language?
