Fish breathe underwater through gills that remove dissolved oxygen from the water. What phenomenon allows oxygen to dissolve in water

The correct answer is "aeration".

Explanation:

Fish depend on the presence of dissolved oxygen in the water to breathe, because they take oxygen from water in a mechanism known as countercurrent exchange. Oxygen gets dissolved in water when winds stirs it in a phenomenon known as aeration. Aeration brings water and oxygen in direct contact, and not only is responsible of producing dissolved oxygen in water, but also increases its palpability by removing its flat taste.
