(very important, answer asap! ) what characteristic makes osmosis different from diffusion? ( no guesses! i have tried but cannot seem to pick. you! ) a. osmosis occurs through a semipermeable membrane. diffusion occurs through a permeable membrane. b. net movement in osmosis is from areas of higher concentration to areas of lower concentration. net movement in diffusion occurs from areas of higher concentration to areas of lower concentration. c. osmosis requires facilitation by an energy carrying module, such as atp. diffusion requires no additional energy to move molecules across the concentration gradient. d. osmosis is used for gases, such as oxygen and carbon dioxide. diffusion is used for water that contains salt or sugar molecules. no long-winded copy and paste "essays"/big paragraphs from a wiki, website, etc. just comment the letter answer. the right answer will get brainliest! you so much, this is very important so give a correct answer! i'm giving 30 points for this. if you just comment "idk" or "lol i don't know" just to get points you will be reported (its happened way too many you so much!
