- facilitated diffusion
What is the monomer of a lipid? - monosaccharide - amino acid - fatty acid - nucleic acid
- fatty acid
What is the main function of a lipid? - short term energy storage - carries genetic information - forms cell membranes, long term energy storage - storage, movement, enzymes
- forms cell membranes, long term energy storage

- relatively low boiling point
What is the main function of a carbohydrate? - short term energy storage - storage, regulatory, enzymes - long term energy storage, insulation, forms cell membranes - carries genetic information
- short term energy storage
What property of water helps to moderate the Earth's temperature? - cohesion - adhesion - specific heat - evaporation
- specific heat
Why is water considered a polar molecule? - the oxygen end is slightly negative and the hydrogen end is slightly positive - the hydrogen and oxygen are bonded together with a hydrogen bond - because it is hydrophobic - the hydrogen end is slightly negative and the oxygen end is slightly positive
- the oxygen end is slightly negative and the hydrogen end is slightly positive
A 0.9% NaCl solution is isotonic to red blood cells. Which of these describes the results if red blood cells are placed into a 9.0% solution of NaCl? - they will burst - they will shrink - nothing will happen - they will expand but not burst
- they will shrink
When you mix salad dressing and water, they immediately separate because... - water does not dissolve oil - salad dressing is too dense - hydrogen bonds form between water molecules - it depends on what kind of salad dressing you are using
- water does not dissolve oil
