100
Type of bond that holds the atoms in a single molecule of water together.
What are polar covalent bonds?
100
The branch of chemistry devoted to carbon compounds.
What is organic chemistry?
100
Polymers built of simple sugars.

200
The main source of ENERGY for producers
What is LIGHT energy?
200
This number of these subatomic particles determines the identity of a chemical element.
What are protons?
200
This type of bond between water molecules must be broken for water to evaporate.
What are hydrogen bonds?
200
Number of bonds that can be formed by a single carbon atom.
What is 4?

What are isotopes?
300
Water reaches its greatest density at this temperature.
What is 4 degrees Celcius?
300
Term for two molecules with the same molecular formula but different structures due to their spatial arrangement around a double bond.
What is a geometric isomer?
300
This type of macromolecule uses nucleotides as its building blocks.
What are nucleic acids?
400
The lowest level of biological organization that can perform all of the activities required for life.
What is the CELL?

What are valence electrons?
400
A neutral solution will have equal concentrations of these two ions.
What are H+ (hydrogen ions) and OH- (hydroxide ions)?
400
Term used to describe the functional group that gives the term "amino acid" the "acid" part of its name.
What is a carboxyl group?
400
This type of macromolecule uses amino acids as its building blocks.
What are proteins?
500
Biological term reflective of the phrase "the whole is greater than the sum of its parts"

What is electronegativity?
500
Term for solutions able to maintain a relatively constant pH when either acids or bases are added to them.
What is a buffer?
500
The functional group responsible for stabilizing proteins by forming covalent cross-links within or between protein molecules (hair example).
What is a sulfhydryl group (thiol)?
500
This type of reaction is used to break polymers into simple monomers.
