Which risk increases when estuarine species experience rapid salinity shifts?

💡 Explanation

Disrupted cellular osmotic balance occurs because rapid salinity changes overwhelm osmoregulation mechanisms, leading to cell damage; therefore osmotic stress increases, rather than stable enzyme activity or metabolic resilience which requires different conditions.
