It is likely that genes, proteins, or receptors differ in structural configuration across taxa, and even if the differences are very small, they may constitute the basis for different effects and reactions in test species when exposed to the same substances and concentrations.
They differ in intensity, configuration and depth of penetration.
The various classes of speech sounds differ in their configuration of acoustic features.
The two methods consist, respectively, of a furnace cycle test and a burner rig test that differ in their configuration (disk relative to cylinder) and in their cycle time/rate.
Early visual impairment can also have long-lasting and broad effects on face discrimination – just a few months of visual impairment due to congenital cataracts can lead to diminished discrimination between faces that differ in their configuration, for example (Le Grand et al., 2001).
The two species also differ in the configuration of the inner back corner of the lower molars.
With one exception, all sympatric species in four communities differ in dewlap configuration.
As 3-epi-25-OHD3 3-epi-25-OHD3 3-epi-25-OHD3 3-epi-25-OHD3ion of the 3-hydroxy group, following oxidandon with cholesterol oxidase then GP derivatisation their products are identical.
We initially thought that 2 and 3 might differ in the configuration of the hydroxy group inserted at C20 because if the cytochrome P450 hydroxylase SalD were confronted with a non-native substrate this enzyme might no longer discriminate between the two C=H bonds at this position.
They differ in their configurations, components and working fluids, and have therefore various operating conditions and equipment inventory.
