1. A SUBATOMIC PARTICLE HAS A NEGATIVE AN ELECTRON
CHARGE AND IS FOUND IN A SHELL OF THE
ATOM. WHAT IS THE PARTICLE?
2. MALE PEACOCKS COMPETE WITH ONE AN- SEXUAL SELECTION
OTHER TO MATE FEMALE PEACOCKS. MALES
WITH MORE COLORFUL TAIL FEATHERS AT-
TRACT FEMALE MATES AT A HIGHER RATE
THAN THOSE W/O. THEREFORE MALE PEA-
COCKS HAVE COLORFUL TAIL FEATHERS,
WHEREAS FEMALE PEACOCKS DO NOT.
WHAT IS THIS AN EXAMPLE OF?
3. A GARDENER MAINTAINS A SPECIES OF MUTATION
ROSE THAT PRODUCD EITHER YELLO FLOW-
ERS ( THE DOMINANT PHENOTYPE) OR WHITE
FLOWERS ( THE RECESSIVE PHENOTYPE).
ONE DAY, THE GARDENER OBSERVES THAT A
CROSS BETWEEN TWO YELLOW ROSE BUSH-
ES 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?
4. SOME CELLS NEED TO MAINTAIN A SET OF ACTIVE TRANSPORT
CENCENTRATIONS OF Na+ AND K+ IONS.
THESE CELLS ARE ABLE TO DO THIS WITH
THE HELP OF THE Na/K PUMP, WHICH TRANS-
PORTS THESE IONS FROM AREAS OF LOW
CONCENTRATION TO AREAS OF HIGH CON-
CETRATION ( AGAINST THEIR CONCENTRA-
TION GRADIENT). Na+ IS PUMPED OUT AND
K+ IS PUMPED IN. WHICH TYPE OF MEM-
BRANE TRANSPORT IS INVOLVED IN THIS AC-
TION?
5. CHROMOSOMES ARE STRUCTURES THAT DNA

WHICH ORGANIC MOLECULE MUST BE PRE-
SENT IN CHROMOSOMES?
6. A CELL HAS DIVIDED ITS CHROMOSOMES CYTOKENESIS
INTO WO NEW NUCLEI. THE CYTOSKELETON
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?
7. THERE ARE FOUR SPECIES OF WOODPECK- COMMUNITY
ERS THAT INHABIT THE PINE FORESTS IN THE
SOUTHEASTERN AREA OF THE U.S. INDIVIDU-
ALS OF THIS SPECIES UTILIZE MANY OF THE
SAME RESOURCES FOR FOOD AND NESTING.
WHICH LEVEL OF ECOLOGICAL ORGANIZA-
TION DESCRIBES THE RELATIONSHIP AMONG
THESE FOUR SPECIES OF WOODEPECKER?
8. TWO SPECIES OF WOODPECKER INHAB- COMPETITION
IT THE SAME LOBLOLLY PINE WOODLAND
THROUGHOUT THE SOUTHEASTERN U.S.
EACH SPECIES REQUIRES RECENTLY DE-
CEASED (BUT STILL STANDING) PINE TREES
FOR REPRODUCTION . THE WOODPECK-
ERS 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 RELA-
TIONSHIP BETWEEN THESE TWO SPECIES OF
WOODPECKER AN EXAMPLE OF?
9. WHILE ABROAD, A TRAVELER DRINKS PARASITISM
UNCLEAN WATER CONTAINING TAPEWORM
CYSTS. THE TAPEWORM ATTACHES TO THE

GOING NAUSEA, LOSS OF APPETITE, AND
WEIGHT LOSS DUE TO THE PRESENCE OF
THE TAPEWORM IN HIS INTESTINES. WHAT
IS THE INTERACTION BETWEEN THE TAPE-
WORM AND THE TRAVELER AND EXMPLE OF?
10. WHAT IS THE CHARGE OF A PROTON? +1
11. A MOLECULAR BONDD RESULTS FROM AN IONIC
ELECTRON BEING TRANSFERRED FROM ONE
ATOM TO ANOTHER. WHICH TYPE OF BOND
HOLDS THESE ATOMS TOGETHER?
12. WHICH SITUATION DESCRIBES COVALENT AN ATOM SHARES AN
BONDING? ELECTRON WITH AN-
OTHER ATOM.
13. WHICH ITEM WOULD BE CLASSIFIED AS BIOT- FUNGUS
IC?
14. WHICH ITEM IS AN ATOM? NITROGEN
15. LARGEMOUTH BASS HAVE INTRODUCED FASTER THAN AVER-
INTO PONDA THAT PREVIOULSY DID NOT AGE SWIM SPEED

WHICH ADAPTATION WOULD HELP THE EX-
ISTING POPULATION OF SMALL, PREY
SPECIES OF FISH AVOID PREDATION FROM
THE LARGE MOUTH BASS?
