help!!!!

Answer 1

The small circles represent molecules of oxygen. Which best describes how the oxygen molecules will move during diffusion?



A.
Oxygen will diffuse from an area of lower concentration (inside the cell) to an area of higher concentration (outside the cell).

B.
Oxygen will diffuse from an area of higher concentration (inside the cell) to an area of lower concentration (outside the cell).

C.
Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell).

D.
Oxygen will diffuse from an area of lower concentration (outside the cell) to an area of higher concentration (inside the cell).

Answer 3

So from that picture, you can agree that there are more \(O_2\) molecules inside the cell, right?

Answer 4

yes

Answer 5

Now, you know (or you should) that diffusion occurs along a concentration gradient; in other words, the molecules diffuse from an area of high concentration to low concentration. With that information, can you now solve this?

Answer 6

im guess it b :}

Answer 7

no need to guess, it is B!

Answer 8

Thank you!!!( and im trying to fan you but it wont let me :/

Answer 9
