Suppose you plant a seed and observe that a tree of large mass grows from it.The tree achieves a final mass that changes very little for years afterward.which of the following is true about the tree. A Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing but then all reactions stopped when the tree reached a stable mass. B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass. C Only anabolic and catabolic reactions took place in the seed and tree when it was young and growing and only catabolic reactions continue now that the tree reached a stable mass D only catabolic reactions took place in the seed and tree when it was young and growing and only anabolic reactions continue now that the tree has reached a stable mass
