Answer:
Explanation:
As we know that the formula for pH is
![pH = -[log H+]\\](https://tex.z-dn.net/?f=pH%20%3D%20-%5Blog%20H%2B%5D%5C%5C)
It is also given in the question that one pH unit represents the 10 fold change in the concentration of hydrogen ion.
Now for lemon juice whose pH is 2, hydrogen ion concentration is equal to
And for pure water whose pH is 
, hydrogen ion concentration is equal to
Thus, the H+ ion concentration in lemon juice is 
times greater than the pure water.
Reproduction is important for survival because it prevent extinction and some individual living things may not preproduce because of mutations in the cells
