Definitions:

Potassium Cotransport

A mechanism involving the simultaneous transport of potassium and another substance across a cell membrane.

Concentration Gradient

The process by which the concentration of molecules moves from an area of higher concentration to an area of lower concentration, a fundamental principle in diffusion.

Dissolved Oxygen

The amount of oxygen present in water, crucial for the respiration of aquatic life and a key indicator of water quality.

Diaphragm

The diaphragm is a major muscle involved in respiration, separating the thoracic cavity from the abdominal cavity and contracting to allow inhalation.
