The attraction among water molecules which hold water together is called:
Correct answer: B. Cohesion.
- A. Tension.
- B. Cohesion.
- C. Adhesion.
- D. Ambibition.
Explanation
Cohesion: Hydrogen bonds make water sticky. Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a "sticky" liquid.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
