 (Big Idea 1 # 17 Deuterostome)  Deuterostomes have two hypotheses on what are truly deuterostomes.  Both hypotheses agree that chordates are deuterostomes.  This fish is a deuterostome because it is a chordate.
(Big Idea 1 #35 Gnathostome)  A gnathostome is any jawed vertebrate.  The fish in this picture are gnathostomes because they have spines and jaws.

(Big Idea 2 #15 Enzyme)  An enzyme is a chemical agent that changes the rate of a reaction without being consumed in the reaction.  This spit is an example of an enzyme because it contains the enzyme salivary amylase.

(Big Idea 3 #1 Diploid)  Diploid means that a cell contains two full sets of chromosomes.  This plant is diploid because it has two full sets of chromosomes in all of its cells.

(Big Idea 3 #3 Eukaryote)  A eukaryote is a organism with the type of cell that has a membrane enclosed nucleus and membrane enclosed organelles.  This fern is an example of a eukaryote because it only has eukaryotic cells.

(Big Idea 2 # 10 Cohesion of water)  Cohesion is a property of water that enables the hydrogen bonds to come together.  The puddle from the ice shows cohesion of water.  If water was not cohesive, then there would be many small puddles instead of one large puddle.

(Big Idea 2 # 37 Unsaturated fat)  Unsaturated fat is a fatty acid that possesses one or more double bonds between the carbons in the hydrocarbon tail.  This vegetable oil is an example of unsaturated fat because it has monounsaturated fat and polyunsaturated fat.  

(Big Idea 2 # 24 Hydrophobic)  Hydrophobic means anything that has an aversion to water.  The vegetable oil is hydrophobic because it will not coalesce with water, so it just sits on top.

(Big Idea 3 # 6 Haploid)  Haploid means anything with half of the number of a full set of chromosomes.  This unfertilized egg is an example of haploid because it only has half of the number of chromosomes in order to be considered diploid.  

(Big Idea 2 # 14 Entropy)  Entropy is a quantitative measure of disorder or randomness.  This desk shows a random arrangement, which is an example of entropy.

(Big Idea 2 # 9 Chitin)  Chitin is a polysaccharide of an amino sugar found in many arthropod skeletons.  The arthropod in the picture with the exoskeleton shows how the outer shell is made of chitin.

(Big Idea 1 # 8 Arachnid)  An arachnid is a subdivision of arthropods.  All arachnids have a cephalothorax, six pairs of appendages, and a pair of pedipalps.  This spider is an arachnid because it has six pairs of appendages.

(Big Idea 1 # 10 Arthropod)  An arthropod is an animal that has joint appendages and a segmented exoskeleton. These crabs are arthropods because they have an exoskeleton and joint appendages.

(Big Idea 1 # 41 Vestigial structure)  Vestigial structure is a homologous characteristic of organisms that have lost all or most of the their original functions.  The coccyx in this model show how the tail has lost all of its function, making it a vestigial structure.

(Big Idea 2 # 19 Heterotroph)  A heterotroph is any organism that consumes other organisms in order to gain energy.  The bird on the power line is a heterotroph because it cannot make its own energy.

(Big Idea 2 # 1 Adhesion of water)  Adhesion of water is the ability of water that can stick to other surfaces.  The water in the straw shows how water sticks to the sides of the straw.

(Big Idea 2 # 2 Anabolic)  Anabolic is any process that synthesizes smaller things into bigger things.  These small legos combine to make one bigger lego which is anabolic.

(Big Idea 2 # 7 Catabolic)  Catabolic is any process in which a bigger thing is made into a smaller thing.  The formerly big stack of legos went under a catabolic process, and now the big stack is broken down.

(Big Idea 1 # 37 Radial Symmetry)  Radial symmetry is a characterizing body shape with many equal parts.  This starfish has radial symmetry because of all of its appendages.

(Big Idea 3 # 10 Behavior)  Behavior is anything an animal does and how it does it.  This squirrel is eating a berry, which shows how it eats a certain type of food.
