I think it is 1 and 2

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.
I’m pretty sure those are the right answers
The correct answer is - Temperate highland.
The climate type in Brazil, in which the snow is a common occurrence in certain period of the year, is the temperate highland climate zone. It is located in the southern part of the country, and it is a climate zone where the dominant land features are the highlands.
Snow can occasionally occur in the other climate zones, like the temperate oceanic (also in the southern part of the country), or even in the tropical monsoon climate zone in the southeastern part of the country, but that is very rare.
Answer;
Evaporation is when water vapor comes from liquid surface water, such as streams, lakes, rivers, and oceans. ... Transpiration is when water vapor comes from liquid water excreted by plants. Plants 'breathe' by exchanging carbon dioxide for oxygen through small openings in their leaves called stomata during photosynthesis.
