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.
Answer:
Hi! your answer should be (A.) Usually the first line of the poem
Explanation:
If you look up any of her poems (ex: "Because I could not stop for Death" and "I heard a Fly buzz-when I died") the name of the poems are the first line of the poems.
I will definitely feel bad about what happen, try to help if i can by doing fundraising's, going to the family of the included people and donate things for their mental stage. <span />
Answer:
Explanation:
motivated to take action to reduce feelings of discomfort
its a motivator for change
Cognitive dissonance causes feelings of unease and tension, and people attempt to relieve this discomfort in different ways. Examples include “explaining things away” or rejecting new information that conflicts with their existing beliefs
Do you have any options for this question or no?
