Question

If oxygen moves from an area of high concentration outside of the cell to low concentration inside the cell, which method of movement is this?
A.) osmosis
B.) diffusion
C.) active transport
D.) Semipermeability

Answer 1

Answer:

B.) Diffusion

Explanation:

Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.

Answer 2

It’s B.) diffusion
Trust me just did this last week
