Okay, can someone please explain to me bony fish and cartileginous fish? And also gaseous exchange in frogs. (please don't spam for points, that's not very nice) Also please like, dumb it down a bit if that's not too much to ask.

I do not know the answer to "please explain to me bony fish and cartilaginous fish?"I have no idea what ur asking, are u saying to define their features? But for the gaseous exchange with frogs:Frog respiration

Explanation:

The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings. If u need me to explain more about frog respiration please dont hesitate to ask

Hope this helps!-jade
