Why can gills only absorb oxygen dissolved in water, and not straight fro the air?

The Last Word weekly top questions – 23 July 2010

Welcome to this Friday's round-up of the week's top questions.

Ever been puzzled how you can blow both cold and hot air out of your mouth? purple2410 asked The Last Word , and got some very interesting replies.

A discussion on whether a body will use more calories and water if there is more available to it branched into the effect of weight on the speed of freewheeling downhill on a bicycle.

Here's one that has always puzzled me: how do fish get up to the top of a mountain ?

Last Worder Milon has some ducks that are behaving strangely… they seem to want to play with their own version of a rubber duck. Can you explain why?

Finally, today's question gets to the lungs of the matter: what causes the burning feeling you get in your throat and lungs when you exercise beyond your normal capacity?

All the best,

Kat

How do you get fish at the top of a mountain?

During a walk last Easter to the Summit of Mt Kosciuszko (Australia's highest mountain) I was suprised to spot some fish swimming in a small pool approximately 200M from the top of the mountain. The pool appeared to be a small man-made drainage channel that drained under the walkway. My question is how did the possibly get there? The mountain is covered in freezing snow for most of the winter months (July - September) so I thought it unlikely that they woud survive. They cannot have existed there since day dot. Did someone put them there?

This fish was caught mid november on rod and line from the river Mersey, UK. What is it? We sent this picture to a biological station and they couldnt tell us what it was. i have never seen this fish ever let alone where it was caught. Can anyone tell us what it is and how it would get there?
