Thus, in dark background, dark-colored moths could camouflage and escape from the predator (birds). So their chances for the survival and reproduction were higher than those of light-colored moths. When the pollution was reduced, the light colored moths were beneficial for survival.
So, the conclusion is that changes in the environment caused changes in the characteristics that were most beneficial for survival.
The cell would shrivel. This is due to the fact that it would lose water to the surrounding 2% sugar solution through osmosis. The surrounding sugar solution is more concentrated hence hypertonic compared to the cell solution of 1%. Water, in osmosis, moves from a hypotonic solution to a hypertonic solution, through a semipermiable, until an isotonic balance is achieved.
