Answer:
B
Explanation:
Valleys are created by streams of running water
1. The correct answer is; are body cells is going to shrink. <span>Salty seawater is a hyperosmotic solution, meaning that it has more solutes than the cell inside. The water will move (from the cell) via osmosis in order for the solutions to reach equilibrium. Also, salty solution exerts more pressure on the of the cell, so the cell will shrink.</span>

2. The correct answer cells in the fish will stay the same size. This will occur because both solutions, freshwater lake and river have similar (or equal) solute concentrations. Those solutions are called isosmotic. There is no movement of water or the solutes, so the cell stays the same.</span>
3. The correct answer is to swell. <span>This will happen because sea star egg has the same solute concentration as its first environment-ocean meaning that this solution is hyperosmotic comparing to the lake (ocean is saltier than the lake, it has more solutes). When you put the sea star egg in the lake, the water from the lake will move (via osmosis) into the egg, to reach equilibrium. Water will cause the cell to swell.</span>
B is the most effective and feasible, and it prevents the initial introdution of the species
Oh boy, there's many, many, many, many...
(many x100)
many ways!
One way is to take shorter showers and conserve water wherever you go, at home, at a restaurant, hotel, etc.
Another way is to not litter on the streets.
Or, spread the word and tell everyone to conserve water, not litter, or just anything to help the environment!
