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.

Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol, SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses, SRP binds to its receptor, Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
