The correct answer for the problem is c
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.
The model that describes how data is written to a blockchain is the: append-only data structure.
<h3>What is an Append-only Data Structure?</h3>
Append-only is computer data storage property whereby new data can be added to a blockchain, like an additional block, in a time-ordered sequential order in such a way that the data added cannot be easily altered as al data are permanently stored across all nodes.
The append-only data structure makes data stored almost immutable. This is the model in which the blockchain technology is built on.
Therefore, the model that describes how data is written to a blockchain is the: append-only data structure.

Answer:
essay below
Explanation:
Government plays a large factor in today's society and has a lot of control over it. Government should be monitoring and changing today's society in a positive way.
The first souce indicates that the government allowed children to work in dangerous conditions, and it was unhealthy as a whole towards everyone who worked there. This was later changed after laws were passed.
The second source shows food insecurity among Inuit Children, the government is needed in areas like these to help support their civilians.
The third source shows equality towards all, now while this is not present throughout the societies of the world and sometimes even governments, this is something that the government should contribute in.
Overall, I suggest that the government should be helping modify today's society and it's problems, such as homelessness, going hungry, healthcare, worker's rights, etc.
