Life treats you in surprises

Sorry about the lack of posts for the last few months- as many of you will know, the last month has not been what I expected! Its been one of those things where until it happens to you, you think your invincible. Clearly I am not!
Anyway...I have been thinking...far too much, hence the strange questions I have had to ask and research:
Do Banana's melt?
Well, to be honest, this was puzzling me greatly. All those memories of scout camps when you place a banana with mars bar inside in the embers, and let it cook, the banana always goes mushy right?! But it never quite becomes "liquid"... that wouldn't be nice! So what does it do then?
So, after asking my chemistry teacher, who thought it was a very strange question, I descovered the true answer. Bananas don't melt! The mushyness is the pectin (protein) in the banana denaturing due to temperature and breaking down :) <---this is not melting!!!
Do worms have mouths?
Right, so worms are quite small, and they don't have a visible mouth, but how do they eat?!
This was a question for google!! The truth is that worms do have an "opening" which could technically be counted as a mouth, but this is actually a tube through the whole length of the worm. The food doesn't actually get digested, the nutrients are just absorbed in the tube.

I think thats enough questions for now :o)  I hope you found my descoveries as interesting as I did!!
