Liquid as first of all, the particles aren't compact ( which would mean solid) nor are they spread out ( which would mean gas) nor is it plasma as we aren't given protons or electrons.
Answer: K+ will flow from side 2 to side 1 until it is in equal concentrations in the two compartments
Explanation: A membrane potential will develop so that the electrical gradient stops the movement of K+ before equilibrium of the concentration can occur
When the fish is put into fresh water, suddenly the concentration around them is very low and the water potential is extremely high. Water will now move from the relatively high water potential in the water to the relatively low water potential in the cells, the cells start to burst and the fish dies.
The outer ring is is the ever first ring but the inner ones tell if it’s old or not.
Megakaryocytes is the answer
