Which outcome primarily occurs when salmon return to natal streams due to disruption of certain neural receptors?

💡 Explanation

Salmon rely on olfactory receptor neurons in their nares to detect unique chemical signatures; anosmia arises because interference disrupts natal stream recognition. Therefore, proper homing fails, rather than altered respiration, osmotic imbalance or undulation which depend on metabolic or fluid dynamics.
