What is the difference between osmosis and diffusion?

a. osmosis moves molecules, such as water, through a semipermeable membrane. diffusion moves molecules, such as oxygen and carbon dioxide, through a permeable membrane.

b. osmosis allows all molecules to move from areas of higher concentration to areas of lower concentration. diffusion allows only water molecules to move from areas of higher concentration to areas of lower concentration.

c. osmosis requires facilitation by a channel protein. diffusion requires additional energy from an energy-carrying molecule like atp.

d. osmosis occurs over an area called a concentration gradient. diffusion occurs over a membrane bilayer.

All of them are man made

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
