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.
<span>The air that is found in soil is extremely different from the air that is found in the atmosphere. Why, you ask? Well, it's because the air that are in soils are not exactly exposed to moving air currents, thus the air that is found in soils are more moist and humid.
Good luck with your studies, I hope this helps~!</span>
Karen demonstrates Respect as her principle/code of conduct. Which is C.
Answer: c. Individuals can influence decisions on the ratification of constitutional amendments.
Explanation:
There was no scenario included however this should be the answer. The most popular way for an amendment to the Constitution to be ratified is by two-third of both chambers of Congress proposing an amendment which then has to be ratified by either three-fourths of state conventions or state legislatures.
In the spirit of American democracy, the State Government should act according to the will of the people which means that individuals will be able to influence decisions on the ratification of amendments.
Indeed the Twenty-first amendments proves the influence that individuals have. This Amendment was passed by State convention where delegates from states were chosen to represent the people. The delegates were only chosen based on whether they would vote yes or no to the amendment.
