Which statement is true about water molecules?
The oxygen atom has a negative charge.
The hydrogen atoms do not share electrons.
Water molecules move randomly around each other.
Water molecules cannot dissolve many substances.


Question 2. How does water relate to the ability of a living thing to generate energy?
Water is responsible for the generation of energy in the cell.
The cell is an aqueous environment.
Without the proper balance of water, chemical reactions in cells could not take place.


Question 3. What is the most important role of hydrogen bonding between water molecules?
It enables water molecules to bond to each other.
It allows oxygen and hydrogen atoms to be charged.
It allows cells to keep water in balance.
