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.
When two neurons are activated at the same time, the connection between them will increase; this is called long-term potentiation.
I'll be 26, and have had my daughter at 22.
Just as my mom had me at 16.. I would ask my mom for help; as I have never done it before. Although I know nothing about raising a kid I will try my best to help her, shape her, feel confident, know her worth, and her beauty. Although I wouldn't be the best mom i would still try for my daughter.
Ex; 1.. Learn how to ride a bike with mommy, I would put training wheels on my bike, aswell as hers. We would slowly progress to no training wheels. Everytime she gets frustrated I tell her " practice makes perfect" I would then say " Alright d/n (daughter name) lets pretend that that there is someone following us, and if we stop they are going to be tickling us. So lets go we dont want to be tickled right d/n? " " Are you tired yet? " " Unt Unt, mommy, can we try with no training wheels?" d/n says. I would shake my head and take the wheels off. " Look moma im doing it!" Then I would start smiling , " Good job d/n remember to focus ok? Try your best to focus" * D/N gets off* " Great job D/N lets go get some ice cream to celebrate your hard work."
SORRY I GOT CARRIED AWAY WITH THIS I WAS ABOUT TO WRITE A WHOLE LIFE STORY IMAOOOO

Hope this helps!!(:
