hypotonic
hypertonic
isotonic
diffusion
7. What is it called when a cell wraps the membrane around a particle to take it in as food or for other uses?

diffusion
osmosis
exocytosis
endocytosis
8.
What is it called when a cell uses energy to expel substances from inside the cell into the environment surrounding?

exocytosis
endocytosis

osmosis

Answer 1

look at the suffixes!

hypo - less
hyper - more
iso - same
The above are all related to concentration

exo - outside
endo - inside
The above refer to location of a process

osmosis is the movement of water
diffusion is the movement of molecules (NOT WATER!)

Answer 2

eg : for 6, you can ignore diffusion because it doesn't talk about concentration. That leaves you with HYPO, HYPER or ISO. Which one seems to best fit the bill?

Answer 3

is 6. isotonic and 7. endocytosis and 8. exocytosis? @wilsondanielle
