What is the biggest, most obvious difference between body structure of these two fish

[ANSWER]

• The minnow is found in open streams and has excellent eyesight. The cave fish is found in dark, cave streams. It is blind and has reduced non- functioning eye parts.

And we have been asked to enlist the similarities and differences between the between the respiratory or gas exchange, all kinds of fish and birds and numbers. So so the respiratory organs in fish are deals and in humans and birds in members of the lungs. Right? So basically we have we have first give the similarities and the differences between gills and lungs. So the similarity between both these is that the health too. Dick oxygen from the environment, external environment and the early need carbon dioxide outside the for the united. So both of these structures, they have respiratory membrane and they both presents a large surface area that increases efficiency for gas exchange. Now moving on to the differences between the two structures. So the guilt. These are the respiratory organs in equity animals which includes fishes and the breed oxygen. The helping breathing oxygen dissolved in water. Thank you. Now lungs neither a pair of breathing organs which is located within the chest and the remove carbon dioxide from the body and bring oxygen to the blood. Right? So these are the respiratory organs. Look for me of the mammals as they're nasty birds stage. Now the gills, these are the external extensions of body surface. So basically they are located outside the body. Whereas the lungs, they are located internally into the body within the internal fools. Right, So three from the gears we can we are breathing oxygen that is dissolved in water and through lungs were breathing oxygen present in the is right to mainly of all. Right. So the guilty. They are made up of rules of element through which the water flows continuously and the lungs. They contain the sacs which are connected to the outside through a network of breathing tubes. Right? So the gills, what they do with the gasses, the diffused between the water and capillaries emerged in the flow of water right? When his blood lungs. Here the gasses diffuse between the inhale air entering into the lungs and the capillaries that were present within the lungs. So the when more differences are The girls, they are present in animals with two framework heart where his lungs are present in an an animal with born chambered art. Right? So these other differences and similarities between the gills and the lung and both these organs are very eventual or uh important for the gashes exchanges in the body. Right now, the next question we have been asked, why do fish suffocate when taken out of the water and placed in air? Whereas mammals have located the air in their LDL is replaced with water. So the answer busy to this question is that the fish it takes oxygen. Wire gills and the gills are mainly affected by the ill. The gills require hydration. They take hydration from water. Right? So the surface area of the gills are greatly reduced when fish is taken out of the water with the beyond effect. Exerted by the water, it is essential for the gills to maintain its rigidity and normal configuration. So they they will call collapse into compact mass, resulting in degrees in the surface area. So as the girls, they are taken out, the fishes are removed from the water. The gills they become dry and this leads to suffocation of the fish is on the contrary, the members they tend to support case in the air in their LDL is replaced with water because in the in the L. Villa the diffusion of oxygen occurs and when there is water presenting the L. Villa it will the diffusion of oxygen would rapidly reduce, right for the fluid in the alveoli, cellular fluid and it is motionless. Oxygen must diffuse through it by diffusion. The water lowers the rate of diffusion. Yes, is reduced by water, so the oxygen which is slowly in the into the blood and this is unable to meet the oxygen needs, which leads to suffocation. Right? So this is the reason why fishes tend to or suffocate when taken out of the water. And members tend to suffocate when the water replaces though they're in the locker. Well, Well, I Right. So this is the answer for the two questions

What is the body structure for adaptation of fish?
