Q
What is the theory all about ?
A
It tries to explain why older fish move towards poles from tropics and temprate zone
2
Q
why do they move to poles ?
A
Climate change has raised water temp as a result oxygen dissolved in water is also decreasing thus they tend to move

A
for younger fish the gills can expand so they can adjust but not the older one…..Evolution principle applies heare
4
Q
why hot water has less oxy holding capacity
A
due to large kinetic energy
