Webδ 13 C sample is the delta-value of the organism for 13 C composition; δ 13 C atm is the delta-value of atmospheric CO 2, which is = -7.8‰ the discrimination due to diffusion a = 4.4‰ the carboxylation discrimination b = 30‰ c a is the partial pressure of CO 2 in the external atmosphere, and; c i is the partial pressure of CO 2 in the ... WebThe binding energy that holds the protons and neutrons together comes from some amount of mass such that E=mc^2. If you change the number of bound neutrons or protons, you also change the energy required to bind them together, thus the total mass changes. This is also why individual, unbound protons or neutrons have a mass more than 1 u.
