To keep homeostasis, fish adjust the amount of water and salt inside their body

Question

To keep homeostasis, fish adjust the amount of water and salt inside their body vs. in the seawater around them. If a saltwater fish keeps the total osmolarity of its body fluids at 284 mOsmol/L, whereas the total osmolarity of the seawater around the fish is approximately 148 mOsmol/L, then:

Where is water likely to diffuse (into or out of the fish)?

Where is salt likely to diffuse (into or out of the fish)?

Explain (2-3 sentences) why the water and salt will move in the way you’ve indicated above.

Explanation / Answer

Answer of the following Question: Water has a tendency to move across a membrane from a lower osmolarity to a higher osmolarity

Water has a tendency that flows across the membrane from a lower osmolarity to higher osmolarity.

The osmolarity of fish body fluids at 284 mOsmol/L.

seawater around the fish is approximately 148 mOsmol/L

Becuase fish are having higher Osmol then water flows into fish seawater around the fish is approximately 148 mOsmol/L

dilute side loses water and becomes more concentrated, and the concentrated side gains water to become more dilute, so the two sides become more similar.

Salt will diffuse into sea water from fish because seawater around the fish is approximately 148 mOsmol/L.
