The best answer is B - the fish die.
Acid rain flows through soils. If the soil part of a watershed, aluminum is released from the soil and into the streams and lakes located in that watershed.
This lowers the pH in the lake from between 6 and 8 (which is the normal pH in lakes and streams) to less than 5.
Both increase of aluminum and lower pH are directly toxic to fish and they kill off fish populations
Length of time candle burns is the correct answer.
100%, they should all have ff genes :3
Hi!
One of the ways we make sure data is reliable is by repeating and replicating experiments.
If we consistently get the same results, then this means that the data is both credible and reliable.
Hopefully, this helps! =)
