A partir del concepto de osmorregulación cual es la regulación hídrica y salinas en peces de agua dulce y salada
maks197457 [2]

Answer:

Absorben o excretan agua salada para mantener la homeostasis.

Explicación:

La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.
