The paradox of freedom concerns free choice.

The paradox of freedom is a relativity theory, that cannot be supported by absolutism that defines its application, but it can – and must be – protected by a single model that prevents its abuse. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
