“种瓜得瓜,种豆得豆。”辩证唯物主义认为,内因是事物发展变化的根本原因,是变化的依据。瓜、豆的形状与其染色体的对数相关联,形都是与“某一个数”相关联的。生物的种类、形状与其染色体的对数相关联,分子的主体构型则是由中心原子的价层电子对数来决定的。 “Dialectical melon, beans beans. ” Dialectical materialism that the internal causes of things is the fundamental reason for the development and change is the basis for change. The shape of a melon, bean, is related to the logarithm of its chromosome, and the shape is related to “a certain number ”. The species and shape of the organism are related to the logarithm of their chromosomes. The principal configuration of the molecule is determined by the valence electron logarithm of the central atom.
