Ideal nurse-to-patient ratios, for example, can vary depending on the patient populations served.
It should also be noted that, while Von Baer's third law holds generally, it has been established that interspecific divergence does not increase monotonically over the entire course of development; rather, the earliest stages of ontogeny in vertebrates, for example, can vary substantially between species [ 12].
The amount of yeast you use, for example, can vary depending on the type of beer you wish to make.
For example, hypoglycemia can vary from "glucose level <70 mg/dL," which encompasses the physiological levels of 60 70 mg/dL, to glucose levels <60 mg/dL.
The definition of a matrix remains elusive and even a simple matrix, as for example grain, can vary greatly in content of moisture, fibre, starch or chemical residues [ 4].
For example, one can vary dose in 11 steps from 100 to 200 (obtaining the sequence 100, 110, 120, … 200) and show minimum, mean, and maximum concentration or PD effect.
For example, the pH can vary considerably according to the weather; crashing waves temporarily bring the levels back to normal.
For example, medication costs can vary between studies because of the use of tariffs in solidarity systems which are not comparable to free prices in private systems.
For example, yolk androgens can vary with laying order and influence post-hatching survival or nestling growth rates in multiple species [for review, see 8].
For example, phenotypic divergence can vary quantitatively [8], [12], [13], as can the magnitude of reproductive isolation [17] [19], [33], [34], the degree of genotypic clustering [22], and the extent of lineage sorting in gene genealogies [23] [28].
