What is diffusion and what is osmosis ?

diffusion is the movement of gases from a higher concentration area to a lower concentration area

osmosis is the movement of water molecules from a higher concentration area to a lower concentration area

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
