"The domesticated generations fell from him" means that Buck is losing his civilized characteristics (B).
In this passage, Buck is feeling more and more estranged from where he and his ancestors ("generations") originally come from: as he gets a taste of wild life, he feels less and less like a pet ("domesticated") and more like a feral dog or a wolf.

In the 'Pandora's box', Haphaestus asks the goddesses to give Pandora a gift or a power. In other words he told them to give Pandora some of their powers.
Trees are helpful perennial plants. They help combat climate change, clean the air, provide oxygen, cool the environment, and help prevent water pollution and soil erosion and a number of other benefits. Without trees, surviving life here on earth would be impossible. Trees absorb carbon dioxide and release oxygen back into the air. They can also absorb odors and harmful gases and pollutants in the air by trapping them on their leaves and bark. They provide oxygen and have the capacity to cool the environment by bringing shades and releasing water vapor through their leaves. They help prevent water pollution, too, since they prevent rainfall from carrying pollutants to the ocean and other bodies of water. In preventing soil erosion, they have the capability to hold soil in place.
