Answer:
Osmosis is the movement of molecules from a region of lower concentration to a region of higher concentration through a semi-permeable membrane
WHILST
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration until the molecules are evenly distributed
Answer:
The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.
Explanation:
The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.
The equilibrium condition may be defined as the condition at which the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.
Thus, the correct answer is option (D).

<span>Independent variable: Time plants are watered (ex. 8am, 12pm, 4pm, 8pm, 12am)
Dependent variable: growth of the plant
Controlled variable: 1. same type plants, 2. same amount of sunlight, 3. same type of dirt, 4. same type of water, 5. same amount of water (each are self explanatory of how to control)</span>
