Why can water have no net charge but have slight charges in different parts of the molecule?

• The oxygen end is slightly negative and the hydrogen end is slightly positive

• The hydrogen and oxygen ends change in polarity

• The hydrogen end is slightly negative and the oxygen end is slightly negative

• Because it is hydrophobic

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes

• Water is pulled by gravity

• Cohesion and Adhesion work together in capillary action to pull the water molecules like a chain
