• Cities were at the center of all early civilizations. People from surrounding areas came to cities to live, work, and trade. ... Cities concentrated political, religious, and social institutions that were previously spread across many smaller, separate communities, which contributed to the development of states.

• From X to Y, decreasing the concentration gradient of sucrose
• Most water molecular move from x to y decreasing the concentration gradient of sucrose. The solution will always move down the concentration gradient. 
• This means the water always move from this is more water to where there is less water.
• Therefore, water will move from a hypotonic solution to the hypertonic solution.
