Properties of Water
Attraction between like water molecules.
What is Cohesion?
Attraction between different types of molecules.
What is Adhesion?
This element must be present for a substance to be considered organic.
What is Carbon?
What is Fats/Triglycerides?
These are the four categories of Biological Molecules.
Water can resist changes in temp. because H-bonds must absorb heat to be broken
What is High Specific Heat?
This is the type of chemical bond found in a single water molecular that is responsible for its polarity.
What is Polar Covalent bond?
Large molecules made from smaller subunit molecules. These help make biological molecules.
What are Polymers?
The monomers of Nucleic Acids.
What is nucleotides?
DNA & RNA are this type of biological molecule.
What is Nucleic Acids?
The upward movement of water due to the forces of cohesion, adhesion, and surface tension
What is Capillary Action?
This is a molecular interaction between oppositely charged poles of water molecules.
What is Hydrogen Bond?
These are molecular attachments involved in chemical reactions that help make polymers.
What are Functional Groups?
These biological molecules are the only ones that cannot be considered true polymers.
What are Lipids?
A type of lipid composed of two fatty acids, a glycerol, and a phosphate group. They make up the bilayer of your cells.
What is Phospholipids?
As water molecules evaporate, the surface they evaporate from gets cooler
This is the inward pull on surface H2O molecules from H-bonds below.
What is Surface Tension?
Carbon can form this many single covalent bonds.
What is 4?
These biological molecules have molecular formulas with multiples of the unit CH2O.
What is Carbohydrates?
Two monosaccharides joined together by covalent bonds.
A measure of how acidic or basic (alkaline) a solution is.
What is pH?
This is how water's density as it freezes into a solid helps marine organisms and aquatic ecosystems.
What is Insulates the organisms and environments below from getting too cold and keeps them from freezing their selves due to crystalline structure as it freezes?
This process results in the releasing of a water molecule to combine two monomers into a larger molecular unit.
What is Dehydration Reactions?
These are the three things that make up a Nucleic Acid.
What is Nitrogenous base, Phosphate group, & Sugar?
These are the different molecular parts of the monomers that make up proteins (polypeptides).
What is Amino Group, Carboxyl Group, Carbon skeleton with Hydrogen (Hydrocarbon)?
BONUS: They compose Amino Acids, the monomer of Proteins.
