Excercises pg 251 question 2

Why would these changes kill the fish?
The fish are dying because both there organs and gills are trying to adapt (change), there environment. This is because the water is becoming more and more salty which the fish aren't use to which then results in them dying.

If you were a scientist investigating the fish kill, where would you start and how would you go about the investigation?
Firstly I would start at the lake, testing the salt level of the water which could be effecting the fish.and also the amount of phosphates entering the lake. last of all I would get one of the fish and see what is happening with its organs and gills by dissecting it.
