Explanation:
A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher level of nitrogen and nutrients in it.
Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in the water bodies and low oxygen content, the algae grows in slower rate. Besides, slower growth of algae may also affected by the acid rain that happens near Moose lake, which is harmful for algae growth due ti the presence of sulphur.

The first thing a cell needs to do to divide successfully is to "B.increase its ratio of surface area to volume". This allows the cell to reach a "breaking point" at which it can divide into two separate cells.
