  6. The ability to move up a narrow tube against gravity • Cohesion • Adhesion • Surface tension • Capillary action • Specific heat

  7. Takes a lot of heat to convert water to vapor • Heat of vaporization • Universal solvent • Solid less dense than liquid • Capillary action • Specific heat

  8. All polar and ionic compounds disolve in water • Heat of vaporization • Universal solvent • Solid less dense than liquid • Capillary action • Specific heat

  15. Cohesion and adhesion are components of • Cohesion • Adhesion • Surface tension • Capillary action • Specific heat

  16. Contribute to the transport of water up a narrow tube against gravity • Cohesion • Adhesion • Surface tension • Universal solvent • a and b

  17. Moderates body temperature • Cohesion • Adhesion • Surface tension • Capillary action • Specific heat

  18. Prevents insects from drowning • Cohesion • Adhesion • Surface tension • Capillary action • Specific heat

  19. Blood and sap are able to deliver nutrients to cells due to: • Heat of vaporization • Universal solvent • Solid less dense than liquid • Capillary action • Specific heat

  20. All the magical properties of water are due to • Hydrogen bonding • Nonpolar covalent bonds • Ionic bonds • Disulfide bonds • None of the above

  21. Water is a __________ molecule • Nonpolar • Ionic • Polar • Disulfide • Neutral

  22. Water has a region of slight positive and slight negative due to: • Hydrogen’s high electronegativity • Oxygen’s high electronegativity • Oxygen’s low electronegativity • Hydrogen’s low electronegativity • Water does not have regions of partial charge

  23. The negative region of water is by the: • Oxygen • Hydrogen

  24. The positive region of water is by the • Hydrogen • Oxygen

  25. Hydrogen is bonded to oxygen in water by: • Single nonpolar covalent bonds • Single polar covalent bonds • Ionic bonds • Hydrogen bonds • Double polar covalent bonds

  26. Hydrogen bonds occur: • Between water molecules • Within water molecules • Do not occur with water

  27. Hydrogen bonds are due to the • Polarity of water • Neutrality of water

  28. Water • Is in limited supply so must be recycled • Is in plentiful supply

  29. All are true Except: • Cells are composed mostly of water • Cells are bathed in water • You are 60% water • You can go months without food but only days without water • Life began in water • Water contains lots of energy

  30. All are true about water except: • Water cushions and protects organs • Chemical reactions in cells could not occur without water • Water delivers nutrients and oxygen to cells • Water carries waste away from cells • Water lubricates • Water maintains temperature homeostasis • Lipids dissolve in water

  31. Lipids • Are nonpolar • Have no charge-neutral • Hydrophobic • Mix with water • Make good barriers for cells
