Biology Class Question

Post by bio_logy » Sun Feb 05, 2006 1:57 am

Right now, in Biology 20, we are doing Science 10 Biology review...before we actually start the Biology 20 stuff. Our teacher asked us to answer some questions from the text book relating to the cell theory and cell membranes...I am having trouble with one of them.
Here's the question:

A marathon runner collapses after running on a hot day. Although the runner consumed water along the route, analysis shows that many of the runners' red blood cells had burst. Why did the red blood cells burst? (Hint: On hot days many runners consume drinks that contain sugar, salt and water.)

Can someone help me answer this please?

Hint: osmosis.
And probably your runne was not one of the runner drinking what is hinted in your question, otherwise he wouldn't have collapsed.

What did the parasitic Candiru fish say when it finally found a host? - - "Urethra!!"
