Question

gills in fish helps to observe?​

Answer 1

Explanation:

Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat).

Answer 2

Respiration is the act of generating energy, and it aids in the management of many metabolic processes that occur in the body. This process generates energy that is used to finish numerous operations and make end goods.

Explanation:

• Fish have developed gills, a unique organ that allows them to breathe oxygen and overcome their oxygen-deficient environment.
• Fish collect oxygen from the surrounding water through their gills and deliver it to the bloodstream. This oxygen diffusion to the blood is only possible when the oxygen content in water is higher than in the blood.
• As a result, aquatic organisms' breathing rates are significantly faster than terrestrial organisms' since the amount of dissolved oxygen in water is much lower than in air, and aquatic organisms like fish acquire oxygen from water in the dissolved state.
