Large centrally located vacuole is the characteristic feature of a plant cell. It is a single membrane bound sac like structure that provide structural support to the cell. It also controls turgor pressure. It stores water inside that keeps the plant to stand still. When the plant is fully hydrated, the central vacuole is filled with water and the membrane of the vacuole pushes against the cell wall. this increases the turgor pressure inside the plant cell and the plant cell stands stiff in an upright position.

Answer:

D. Changes in the environment changed each morph's ability to evade predation in different ways.

Explanation:

The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.

When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number  as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.

Therefore, option D is best option.

Hope it help!
