Chapter 9
Chapters 1, 6,7, parts of 2, 3
1) All living things are composed of cells*
2) All cells come from pre-existing cells*
* The Cell Theory
3) All cells exist in a water environment
4) All cells are bounded by a membrane
5) All cells have similar chemistrys (proteins, proteins,
proteins)
6) DNA is the primary heritable molecule (DNA’s BIG job
is to code for proteins)
7) The concept of gene regulation and totipotency

methane, methanol, and amphipathic
Dipole-dipole interactions: Because they have slight positive and
negative charges, polar covalent bonds are attracted to other polar
covalent bonds. A special example of these are HYDROGEN
BONDS – These are sooo important! When H forms covalent
bonds with O or N, the polar bond can form hydrogen bonds with
other atoms. For example, water makes hydrogen bonds with
other water molecules and other POLAR molecules or IONS.
on your handout
Water makes hydrogen bonds with other water molecules and
other POLAR molecules or IONS and these are HYDROPHILIC
(water loving) interactions. Things that dissolve in water are
hydrophobic. Molecules that lack this capability (because they are
composed of nonpolar covalent bonds) are HYDROPHOBIC
(water fearing). Oil does not dissolve in water because the
nonpolar bonds in the oil molecules are hydrophobic.
on your handout
NONCOVALENT INTERACTIONS – These occur between
molecules (or between different parts of large molecules). The
atoms do not share electrons. These are often called noncovalent
“bonds” which is too bad because then they can get confused with
covalent bonds.
1) Dipole-dipole interactions
2) London Dispersion forces
3) Ionic interactions
on your handout
MOLE – This a specific number similar to the concept that 12 is
one “dozen”. You can have a dozen of anything (eggs, donuts,
etc.) and it means you have twelve. Similarly, you can have a
mole of anything (carbon, sucrose, etc.) and it means you have
6.02 x 1023. This funny number was established to make the
following relationships convenient:
MOLARITY - The concentration of a molecule in a solution. One
mole per liter is called a 1 Molar ( 1 M) solution.

Lowering the pH decreases the ability of water to dissolve salt.
