Answer: B. Increased surface runoff has increased water pollutants.
Explanation:
Trees provide a very valuable service in limiting the effects of surface runoff such as the reduction of soil erosion on account of trees holding the soil together with their roots. Their presence also reduces the actual surface runoff because they impede the path of the water.
With deforestation getting rid of trees, they would be unable to anchor the soil and reduce the movement of water which means that surface runoff will increase.
They pull and the same ones push away

Explanation:
I think this is right.... Sorry if not!!
P700 is photosystem I. It includes chlorophyll a 670, 680, 695, 700, Chlorophyll b, carotenoids. The active reaction center of photosystem is p700, as it absorbs light of a wavelength longer than 680nm.
P680 or the photosystem II has the following pigments: chlorophyll b, 660, 670, 680, 695, 700, phycobilins, and xanthophylls. The active reaction center, in this case, is p680 of chlorophyll a, as it absorbs the light having a wavelength shorter than 680nm.
Oil and water separate because they have different densities.
