Why do seas provide habitats with minimum temperature variation?
How does turbulence of water influences the availability of gases?
I read that jellyfish have form in water but collapses into a mass when placed on land, why is that?
Its not really Homework i just read it from a book so its just out of curiosity
Jellyfish are mostly flexible cells filled with water. A balloon filled with water in the sea is nice an round, but if you drag it ashore, yee gads, it is not round anymore.
