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 ANOTH- SEXUAL SELECTION
ER TO MATE FEMALE PEACOCKS. MALES WITH
MORE COLORFUL TAIL FEATHERS ATTRACT FE-
MALE MATES AT A HIGHER RATE THAN THOSE
W/O. THEREFORE MALE PEACOCKS HAVE COL-
ORFUL TAIL FEATHERS, WHEREAS FEMALE PEA-
COCKS DO NOT. WHAT IS THIS AN EXAMPLE OF?
3. A GARDENER MAINTAINS A SPECIES OF ROSE MUTATION
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 FLOW-
ERS. WHAT EVOLUTIONARY MECHANISM IS IN-
VOLVED IN THE CHANGE IN THE GENE POOL OF
THIS SPECIES?
4. SOME CELLS NEED TO MAINTAIN A SET OF CEN- ACTIVE TRANSPORT
CENTRATIONS 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 GRADIENT). Na+ IS
PUMPED OUT AND K+ IS PUMPED IN. WHICH

TYPE OF MEMBRANE TRANSPORT IS INVOLVED
IN THIS ACTION?
5. CHROMOSOMES ARE STRUCTURES THAT CON- DNA
TAIN HEREDITARY MATEIRAL THAT WILL BE
PASSED FROM ONE GENERATION TO THE NEXT.
ACCORDING TO THIS INFORMATION, WHICH
ORGANIC MOLECULE MUST BE PRESENT IN
CHROMOSOMES?
6. A CELL HAS DIVIDED ITS CHROMOSOMES INTO CYTOKENESIS
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-

SAME RESOURCES FOR FOOD AND NESTING.
WHICH LEVEL OF ECOLOGICAL ORGANIZATION
DESCRIBES THE RELATIONSHIP AMONG THESE
FOUR SPECIES OF WOODEPECKER?
8. TWO SPECIES OF WOODPECKER INHABIT THE COMPETITION
SAME LOBLOLLY PINE WOODLAND THROUGH-

9. WHILE ABROAD, A TRAVELER DRINKS UN- PARASITISM
CLEAN WATER CONTAINING TAPEWORM CYSTS.
THE TAPEWORM ATTACHES TO THE INTESTICAL
WALLS OF THE TRAVELER, ABSORBING NUTRI-
ENTS FROM THE PARTIALLY DIGESTED FOOD.
OVER THE NEXT FEW MONTHS, THE TRAVELER
EXPERIENCES ONGOING NAUSEA, LOSS OF AP-
