Browser inconsistencies often create problems. Make sure to print a test page to make sure everything works.
You can do this by setting the pages in the Page Range to 1.
1. Click Here to print these flashcards.
2. Fold each page in half (horizontally).
3. Cut below each flash card.
4. Use tape, glue, or staples to hold the flashcards together.
Polar molecules
slightly charged
nonpolar molecules
no charge
Capillary actions
Water moves upward because of adhesion and cohesion
Hydrogen bonds
slightly positive hydrogen atoms and slightly negative atoms
cohesion
( water to water ) substance attracted to itself
adhesion
substance attracted to a different substance (usually charged)
high specific heat
resist of change of temperature ; water absorbs a lot of heat before changing phase
carbohydrate
element: carbon, hydrogen, oxygen
function: energy in cells
monomer: glucose
example: sugars , starch, cellouse
Lipids
elements: carbon, oxygen, hydrogen
function: energy in cells
monomer: phospholipids , fatty acids
example: olive oil, butter
Proteins
elements: carbon, oxygen, hydrogen nitrogen and sometimes sulfur
function: build muscle, and improve eyesight, movement, digestion
monomer: amino acid
example: meat
Nucleic Acids
elements: carbon, oxygen, hydrogen , phosphate group, nitrogen
function: information
monomer: nuclei-tides
example: DNA , RNA
