Quantitative Laws in Regeneration
It is well known that a long defoliated piece of stem of Bryophyllum calycinum forms shoots only at the apical or the two apical nodes, while when such a stem is cut into as many pieces as there are nodes each node produces shoots. It is shown in this paper that the dry weight of shoots produced in the apical nodes of a long piece of stem is approximately equal to the dry weight of shoots the s...

متن کاملPower laws in biological networks
The rapidly developing theory of complex networks indicates that real networks are not random, but have a highly robust large-scale architecture, governed by strict organizational principles. Here, we focus on the properties of biological networks, discussing their scale-free and hierarchical features. We illustrate the major network characteristics using examples from the metabolic network of ...

1. Equal masses of sister leaves of Bryophyllum calycinum produce equal masses of shoots and roots in equal time and under equal conditions. 2. The mass of shoots and roots produced by different masses of sister leaves in equal time and under equal conditions is approximately in direct proportion to the masses of the leaves. 3. When a piece of stem inhibits the production of shoots and roots in...

Incorporation of plasma-bound iron into ferritin of liver and spleen of the rat is a dynamic process which accounts for 10% of the iron which normally leaves the plasma. It involves the reaction of adenosine triphosphate and ascorbic acid with iron bound to a &globulin of the plasma, transferrin, and leads to the transfer of this iron to ferritin. Evidence for this mechanism has been obtained f...
