Question

What part of a fish helps it rise?Help ASAP​

Answer 1

It’s called a swim bladder
To put it simply, a swim bladder is an organ in which the chambers of this organ fill with gases. An increase of gases cause the fish to rise and decreasing gas will cause it to sink

Answer 2

They use a internal pouch which is named swim bladder.




Explanation; Oxygen will enter a fish’s mouth, and passes through their gills. The oxygen will be taken and gets carried by hemoglobin through their bloodstream. Hemoglobin will take out some of the oxygen into their swim bladder. The amount of oxygen will show if they will sink or rise. Your question is how do they rise. If he goes up too much, the meaning of this is when the gas diffuses into their blood and out the gills.
