Answer:
Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.
Explanation:
Mesopotamia ( Western Asia )was the first place of domestication of wheat. The favourable climate of intense sunshine of old Western Asia-kuwait, Iraq,...) favours photosynthesis which ensure food production,
Besides the population of this region with wide grains, on hilly land, ensured cross pollination of these wide seeds grains with wheat varieties leading to hybridization, and selection by natural selection for domestication and eventual evolution.

Choices 1,3,4, and 6 are correct
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.
