Acid rain throughout the northeast United States has lowered the pH of many ponds and lakes. The lowered pH will eventually result in the death of many aquatic animals. The table shows the pH tolerance levels for water that supports a variety of nine animal species living in a specific habitat. Which animal has the largest zone of tolerance for pH?
A) bass
B) frog
C) mayfly
D) snail

Bass = 5.5

Frog = 4.0

Mayfly = 5.5

Snail = 6.0

The lower it is the more acidic it is/ can take

Explanation:

Hope this helps :)

snail

it is a snail because usa test prep said so

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
