Homework Help: science

Posted by cara on Sunday, September 13, 2009 at 6:54pm.

I posted this before but i realized i posted somethings that were wrong.

mosquito larvae can tolerate extremely low dissolved oxygen concentrations, yet cannot survive at temperatures above 25 degrees celcius. how might you account for dissolved oxygen concentrations of such a low value at a temperature of 25 degree celcius?

In other words, how can it be that at low temperatures, there is high concentrations of dissolved oxygen?

I dont understand how this can be because as the temperature of an area increases, then the concentration of dissolved oxygen decreases.
