1. A SUBATOMIC PARTICLE HAS A NEGATIVE CHARGE AND IS FOUND IN A SHELL
OF THE ATOM. WHAT IS THE PARTICLE?: AN ELECTRON
2. MALE PEACOCKS COMPETE WITH ONE ANOTHER TO MATE FEMALE PEA-
COCKS. MALES WITH MORE COLORFUL TAIL FEATHERS ATTRACT FEMALE MATES
AT A HIGHER RATE THAN THOSE W/O. THEREFORE MALE PEACOCKS HAVE
COLORFUL TAIL FEATHERS, WHEREAS FEMALE PEACOCKS DO NOT. WHAT IS
THIS AN EXAMPLE OF?: SEXUAL SELECTION
3. A GARDENER MAINTAINS A SPECIES OF ROSE THAT PRODUCD EITHER YELLO
FLOWERS ( THE DOMINANT PHENOTYPE) OR WHITE FLOWERS ( THE RECESSIVE
PHENOTYPE). ONE DAY, THE GARDENER OBSERVES THAT A CROSS BETWEEN
TWO YELLOW ROSE BUSHES HAS LED TO A SINGLE ROSE BUSH WITH ORANGE
FLOWERS. WHAT EVOLUTIONARY MECHANISM IS INVOLVED IN THE CHANGE
IN THE GENE POOL OF THIS SPECIES?: MUTATION
4. SOME CELLS NEED TO MAINTAIN A SET OF CENCENTRATIONS OF Na+ AND K+
IONS. THESE CELLS ARE ABLE TO DO THIS WITH THE HELP OF THE Na/K PUMP,
WHICH TRANSPORTS THESE IONS FROM AREAS OF LOW CONCENTRATION TO
AREAS OF HIGH CONCETRATION ( AGAINST THEIR CONCENTRATION GRADI-
ENT). Na+ IS PUMPED OUT AND K+ IS PUMPED IN. WHICH TYPE OF MEMBRANE
TRANSPORT IS INVOLVED IN THIS ACTION?: ACTIVE TRANSPORT
5. CHROMOSOMES ARE STRUCTURES THAT CONTAIN HEREDITARY MATEIRAL
THAT WILL BE PASSED FROM ONE GENERATION TO THE NEXT. ACCORDING
TO THIS INFORMATION, WHICH ORGANIC MOLECULE MUST BE PRESENT IN
CHROMOSOMES?: DNA
6. A CELL HAS DIVIDED ITS CHROMOSOMES INTO WO NEW NUCLEI. THE CY-
TOSKELETON OF THE CELL IS CURRENTLY PINCHING THE CELL IN THE MIDDEL
TO FROM TWO NEW CELLS. IN WHICH STAGE OF THE CELL CYCLE IS THIS
CELL?: CYTOKENESIS
7. THERE ARE FOUR SPECIES OF WOODPECKERS THAT INHABIT THE PINE
FORESTS IN THE SOUTHEASTERN AREA OF THE U.S. INDIVIDUALS OF THIS
SPECIES UTILIZE MANY OF THE SAME RESOURCES FOR FOOD AND NESTING.
WHICH LEVEL OF ECOLOGICAL ORGANIZATION DESCRIBES THE RELATIONSHIP
AMONG THESE FOUR SPECIES OF WOODEPECKER?: COMMUNITY

8. TWO SPECIES OF WOODPECKER INHABIT THE SAME LOBLOLLY PINE WOOD-
LAND THROUGHOUT THE SOUTHEASTERN U.S. EACH SPECIES REQUIRES RE-
CENTLY DECEASED (BUT STILL STANDING) PINE TREES FOR REPRODUCTION .
THE WOODPECKERS EXCAVATE THEIR NEST CAVITIES IN THE DEAD PINE TREES.
IN MOST HEALTHY FORESTS THERE ARE GENERALLY NOT ENOUGH DEAD PINE
TRESS TO PROVIDE NESTS FOR ALL THE WOODPECKERS THAT WANT TO BUILD
THEM. WHAT IS THE RELATIONSHIP BETWEEN THESE TWO SPECIES OF WOOD-
PECKER AN EXAMPLE OF?: COMPETITION
9. WHILE ABROAD, A TRAVELER DRINKS UNCLEAN WATER CONTAINING TAPE-
WORM CYSTS. THE TAPEWORM ATTACHES TO THE INTESTICAL WALLS OF THE
TRAVELER, ABSORBING NUTRIENTS FROM THE PARTIALLY DIGESTED FOOD.
OVER THE NEXT FEW MONTHS, THE TRAVELER EXPERIENCES ONGOING NAU-
SEA, LOSS OF APPETITE, AND WEIGHT LOSS DUE TO THE PRESENCE OF THE
TAPEWORM IN HIS INTESTINES. WHAT IS THE INTERACTION BETWEEN THE
TAPEWORM AND THE TRAVELER AND EXMPLE OF?: PARASITISM
10. WHAT IS THE CHARGE OF A PROTON?: +1
11. A MOLECULAR BONDD RESULTS FROM AN ELECTRON BEING TRANSFERRED
FROM ONE ATOM TO ANOTHER. WHICH TYPE OF BOND HOLDS THESE ATOMS
TOGETHER?: IONIC
12. WHICH SITUATION DESCRIBES COVALENT BONDING?: AN ATOM SHARES AN ELECTRON
WITH ANOTHER ATOM.
13. WHICH ITEM WOULD BE CLASSIFIED AS BIOTIC?: FUNGUS
14. WHICH ITEM IS AN ATOM?: NITROGEN
15. LARGEMOUTH BASS HAVE INTRODUCED INTO PONDA THAT PREVIOULSY
DID NOT CONTAIN ANY LARGE, PREDATORY FISH. WHICH ADAPTATION WOULD
HELP THE EXISTING POPULATION OF SMALL, PREY SPECIES OF FISH AVOID
PREDATION FROM THE LARGE MOUTH BASS?: FASTER THAN AVERAGE SWIM SPEED
16. WHICH TWO ACTIVITIES ASSIST IN THE MOVEMENT OF WATER THROUGH ITS
CYCLE AND TAKE PLACE IN LIVING THINGS?: PHOTOSYNTHESIS AND AEROBIC RESPIRATION
17. PRARIE ECOSYSTEMS ARE COMMON WITHIN CONTINENTAL INTERIORS IN
THE NORTHERN HEMISPHERE. THESE ECOSYSTEMS HAVE A THICH NUTRIENT
RICH TOP SOIL AND ARE DOMINATED BY GRASSLANDS AND SHRUBS. WHICH
