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.

Answer:Chromatic observation
Explanation:
The dog's reflection on the water's surface is because of light rays reflecting off the dog and onto the water to create a mirror image.
The correct answer is: Disruptive selection
Disruptive selection is a type of natural selection that favors both extreme traits in a population (it is bimodal) over intermediate traits. In the example above, it favors dark and light-snails (both are extreme traits). As a consequence, the population of snails is divided into two distinct groups. This happens because snails with intermediate brightness wouldn’t have suitable environment for them, wouldn’t be adopted to either shady forest or brushy edge areas.
