Which outcome occurs when fish gills operate in extremely cold water?

💡 Explanation

When fish gills operate in extremely cold water, increased blood viscosity inhibits oxygen diffusion because lower temperatures increase fluid resistance in the capillary network, thus limiting gas exchange efficiency. Therefore the increased viscosity reduces diffusion, rather than maximizing uptake, enhancing exchange or accelerating diffusion, which rely on more favorable physiological states.
