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:
In college, your professors rarely reach out to you. High school educators often take more initiative, and would often check in with you if they notice something off. In college, you're expected to take that initiative and actively network with your professors.
Answer:
True.
Explanation:
An argumentative writing can be defined as an expression of a writer's position (stance) on a subject matter or topic.
A claim can be defined as a statement that is used by a writer to prove, substantiate or support an argument.
Thus, a claim is an assertive statement expressed by a writer to prove that an argument is true or real.
This ultimately implies that, when writers engage in an argument or write an argumentative essay, they make use of a claim to state or express their opinions about the subject matter or topic.
All arguments generally have an unstated premise and as such when evaluating an argument, one should always take into consideration the existence and merit of any unstated premises. Premises connotes claims that fundamentally serves as a reason in an argument.
Supply and demand! The prices will rise until the supply will reach the demand.
