Definition
A molecule that has a light positive end and a slight negative end
due to the uneven distribution of electrons (Oxygen is hogging the
electons)
A weak bond between the positive end of one polar molecule and
the negative end of another polar molecule
When water freezes the molecules move farther apart, so water in
its frozen state is LESS dense than in it’s liquid state, so it floats
rather than sinks. This is important so that you can have life in
water
The attraction between to different molecules, like water and
something else
The attraction between two of the same molecules, like water to
water. This is what causes surface tension, allowing things to float
on water, like bugs and leaves. It also is why water forms drops.
Due to cohesion, water molecules stick together
Due to adhesion and cohesion together, water molecules can move
against the force of gravity through small spaces. This is how
plants get water from the ground.
It takes a lot of energy to change the temperature of water. This is
important because it allows water to remains at an almost constant
temperature in our large bodies of water, like oceans. This allows
for marine life, and for climate control worldwide. This property
also helps our bodies maintain homeostasis (the ability to maintain
stable internal conditions)
The substance the you put into the solvent
Solvent and solute
Water is known as the universal solvent because anything polar
will dissolve in it.
The liquid that something dissolves in
A non-polar molecule that cannot break the cohesive force of
hydrogen bonds in water so it DOES NOT dissolve in water.
A molecule that is polar and dissolves in water by breaking the
cohesive forces of the hydrogen bonds between water molecules.

Definition
Energy cannot be created or destroyed. It can only change from one
form to another or be stored.
ATP
Store energy in the form of a carbohydrate (glucose) that they
make through photosynthesis
Cannot make their own food, must eat it to get it
Plants, algae, and some bacteria
In the chloroplasts of leaves
6 carbon dioxide + 6 waters 1 glucose (sugar) + 6 oxygens
Oxygen (a byproduct is something that is produced but not needed
by the organism that produced it)
Chemical bonds. When those bonds are broken, it is released
Cellular respiration
Animals and fungi
Carbon Dioxide and Water
Glucose (sugar) and oxygen
The process where energy in food is converted into ATP by
breaking the chemical bonds.
1 glucose + 6 oxygens 6 carbon dioxides + 6 waters + ATP
Carbon Dioxide and water
Mitochondria
