The small circles represent molecules of oxygen. what will eventually happen to the oxygen molecules when they are in a higher concentration outside the cell? a. oxygen will diffuse from an area of higher concentration (inside the cell) to an area of lower concentration (outside the cell). b. oxygen will diffuse from an area of lower concentration (inside the cell) to an area of higher concentration (outside the cell). c. oxygen will diffuse from an area of lower concentration (outside the cell) to an area of higher concentration (inside the cell). d. oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell).
