what is the ratio of a wave's height and length called?
wave steepnes
individual waves in deep water break when the wave steepness—the ratio of the wave height "h" to the wavelength "λ"—exceeds about 0.17, so for "h"  0.17 "λ". in shallow water, with the water depth small compared to the wavelength, the individual waves break when their wave height "h" is larger than 0.8 times the water depth "h", that is "h"  0.8 "h". waves can also break if the wind grows strong enough to blow the crest off the base of the wave.

granins (chromogranins or secretogranins) are acidic proteins and are present in the secretory granules of a wide variety of endocrine and neuro-endocrine cells. the exact function(s) of these proteins is not yet settled but there is evidence that granins function as pro-hormones, giving rise to an array of peptide fragments for which autocrine, paracrine, and endocrine activities have been demonstrated in vitro and in vivo. the intracellular biochemistry of granins includes binding of ca, atp and catecholamines (epinephrine, norepinephrine) within the hormone storage vesicle core. there is also evidence that cga, and perhaps other granins, regulate the biogenesis of dense-core secretory vesicles and hormone sequestration in neuroendocrine cells.
