According to anthropologists, why did people moved to the Northern Nile River? (Site 1)

The correct answer is - it provided water, food, transportation, and excellent, fertile soil for growing food.

Explanation:

People of Egypt moved to the northern Nile river due to various reasons. In this region, the soil is very excellent and helps in growing crops as the soil is fertile due to the appropriate climate and water resources.

It is aso helps in selling and transporting the products as it was a trade route at the time. As it is known Egypt has almost no rainfall so the only way crops can get water is through the Nile river.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
