Which consequence results when excessive freshwater influx overwhelms a salmon's active osmoregulation?

💡 Explanation

Reduced salinity causes water influx; the effect overwhelms active transport, causing hyposmotic conditions. Active osmoregulation removes water, but it is insufficient because the influx is too great; therefore, plasma osmolarity drops excessively rather than maintaining ion balance or altering kidneys.
