STEP ONE Okay first you want to make sure that your shoe lace is undone.
STEP TWO Then your gonna wanna cross the two shoe laces over so it looks like an x
STEP THREE Then you will want to pull on both end so its tight.
STEP FOUR Next your gonna wanna make one hoop so it kinda looks like a bunny ear but leave one lace undone.
STEP FIVE After you have made a hoop and left one lace undone you are going to want to wrap the lace that you had undone around the hoop.
STEP SIX After you have wrapped the undone lace around the hoop your gonna want to put it threw the little opening you are going to make with the undone lace and pull it threw so it looks like you have to loops.
STEP SEVEN Now you know how to tie your shoes :)
....and yes I did type that all out because I felt like it
Binocular cues include stereopsis, eye convergence, disparity, and yielding depth from binocular vision through exploitation of parallax. Monocular cues include size: distant objects subtend smaller visual angles than near objects, grain, size, and motion parallax.
Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.
