when an atom or molecule looses an electron.
|
|
|
reduction
|
when an atom or molecule gains an electron.
|
|
|
Atomic energy levels
|
When an electron absorbs energy it moves to a higher energy leve l farther from the nucleus.
|
|
|
Covalent bond
|
When two atoms share one or more pais of valence electrons.
|
|
|
Cohesion
|
When water is attracted to other water molecules.
|
|
|
Adhesion
|
When water molecules are attracted to a different substance.
|
|
|
pH
|
The concentration of hydrogen ions in a solution.
|
|
|
Acids
|
Any substance that increases the pH.
|
|
|
Acidic Solutions
|
Have a pH value lower than 7. The stronger the acid is the more H+ ions it produces and the lower the pH is.
|
|
|
Bases
|
A substance that combines with H+ ions when dissolved in water. H+ plus bases lowers the H+ ions.
|
|
|
Properties of Carbon.
|
Carbon contains 4 covalent electrons so it can create 4 bonds.
|
|
|
Hydrocarbons
|
Covalent bonds between carbon and hydrogen. They store alot of energy, gasoline is a hydrocarbon.
|
|
|

|
|
contents of DNA & RNA and how can they pair.
|
pyrimidines:
Cytosine (DNA & RNA) Thymine (DNA ONLY) Uracil (RNA ONLY) Purines Adenine Guanine Adenine only pairs with Thymine. Cytosine only pairs with guanine |
|
|
Structure of phospholipids
|
Charged organic molecule.
Phosphate group. Glycerol Fatty acid |
|
|
Structure of Fats
|
Glycerol attaches to three fatty acids.
|
|
|
Saturate Fat
|
Contains the maximum possible number of hydrogen atoms.
|
|
|
Unsaturated Fats
|
When it has any double bonds between the hydrogen atoms.
|
|
|
Celullose & Chitin
|
Cellulose in plans and chitin in arthropods, are chains of sugars that resist digestion.
|
|
|
