Document Summary
The body size signal is the most important constraint on physiology across all organisms, especially multicellular organisms. The oxygen consumption at atmospheric oxygen in the cell culture tends to be constant across all species if you remove the cells from the body. Sleep is a critical aspect of all physiology. The body size scales exponentially with a particular exponent = 0. 75: most organisms scale, various functions 65 or 66 which is close to the sav rule or they tend to have exponents close to 0. 75. What does vary between groups is the y-intercept (the intercept part is critical: there"s a separate intercept for unicellular cells, for poikilotherms = ectotherms = cold-blooded, and for homeotherms = endotherms = warm-blooded. The slopes are more of less the same: the biochemistry running those things are conserved across those lineages. Field metabolic rate and body size (body mass vs. field metabolic rate)
