Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, crayfish and clam populations are the first to disappear, then various types of fish.

The lakes, however, do not become totally dead. Some life forms actually benefit from the increased acidity. Lake-bottom plants and mosses, for instance, thrive in acid lakes. So do blackfly larvae.
The weigh of each tomato is the dependent variable
Answer:
mg of powder 1 and 
mg of powder 2
Explanation:
Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture
Total weight of vitamin B1 in the mixture is equal to 
mg
Total weight of vitamin B2 in the mixture is equal to 
mg
Equation 1
Equation 2
Let us simplify the above two equations, we will get
Substituting value of X in equation 2 we get
Answer:
