The table shows the tolerance range of some common freshwater organisms to different pH ranges in water. Acid rain causes the pH
2 answers:
Answer: Frogs will be last to die due to increase in acid rain.
Explanation: Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low.
pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.
Mathematically,
More the hydrogen ion concentration, low will be the pH and vice-versa.
For the given question, the animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die.
From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.
Hence, the correct answer is Frogs.

<h3>What are the cell structure and their functions?</h3>Some explanation on structure of cells is given below:
The nucleus:
This is known to be the key or major organelle that tends to sustain or hold the genetic information that is needed for reproduction and cell growth as well as development.
Note that all cell is known to be made up of one nucleus and also a kind of membrane-bound organelles that can be seen in the cytoplasm.
Mitochondria:
This is known to be a double membrane-bound organelle that is known to function by acting as the site for the energy transactions and it is made for the survival of all cell.
Therefore, The model of the structures of the cell and and their functions is given in the image attached.
