Which type of burn is most likely to leave a scar? why?

A 2nd and 3rd degree will leave a scar because they both damage your tissue and nerves. you can tell if its a 2nd degree if its red and hurts a lot and your skin is blistering red and you can tell its a 3rd degree burn if it doesn't hurt much at all or there's no pain at all and you feel no pain because the nerves are damaged :)

What's the yellow wallpaper?

We are not able to see the stars. light prevents our seeing the stars. i hope it kinda : )
