WHAT ARE THE ADAPTATIONS IN AUSTRALOPITHECUS AFARENSI
REPOSITIONED FOREARM MAGNUM, BASIN, VALGUS ANGLE AT THE KNEE, NON-OPPOSABLE BIG TOE
WHAT IS THE REPOSITIONED FOREARM MAGNUM
THE SPINAL CORD ENTERS THE SKILL FROM THE BASE RATHER THEN THE BACK
WHAT IS A BASIN
SHAPED PELVIS: THE PELVIS SUPPORTS AND BALANCES THE TORSO, SERVING AS THE BODY'S CENTER OF
GRAVITY
WHAT IS VALGUS ANGLE AT THE KNEE
THE FEMURS POINT TOWARD THE KNEES TO SHIFT THE CENTER OF GRAVITY MORE EASILY
WHAT IS NON-OPPOSABLE BIG TOE
THE TOES OF THE FOOT ARE IN LINE TO EFFICIENTLY DIRECT DOWNWARD FORCE TOWARD THE
GROUND.
WHAT IS ALTERNATION OF GENERATION IN PLANTS
PLANTS HAVE A LIFE CYCLE WITH TWO DISTINCT STAGES, THE GAMETOPHYTE STAGE AND THE
SPOROPHYTE STAGE. CYCLING BETWEEN THESES TWO IS KNOWN AS ALTERNATION OF GENERATIONS.
IN THE HAPLOID GAMETOPHYTE STAGE, GAMETES WHICH ARE REPRODUCTIVE CELLS, ARE PRODUCED
,THROUGH MITOSIS. THE MALE AND FEMALE GAMETES FUSE TO FORM A DIPLOID ZYGOTE, WHICH THEN
DEVELOPS INTO THE SPOROPHYTE. THE MATURE SPOROPHYTE PRODUCES SPORES THROUGH MEIOSIS
AND THE SPORES UNDERGO MITOSIS TO PRODUCE THE HAPLOID GAMETOPHYTE.
WHAT IS RADIAL SYMMETRY
CAN BE SPLIT INTO TWO IDENTICAL HALVES BY DRAWING A PLAN THROUGH THEIR LONGITUDINAL AXIS
IN MORE THAN ONE DIRECTION WITH THEIR MOUTH FORMING ONE END OF THIS AXIS. ( JELLYFISH,
ANEMONES, CORALS, COMB JELLIES, ADULT SEA URCHINS AND STARFISH) ANIMALS HAVE A TOP AND
BOTTOM BUT NOT CLEAR LEFT OR RIGHT OR FRONT OR BACK
WHAT IS BILATERAL SYMMETRY
: CAN BE DIVIDED INTO TWO MIRRORED HALVES BY A SAGITTAL PLANE THROUGH THEIR MIDLINE,
SPLITTING THE ANIMAL INTO THE LEFT AND RIGHT SIDES. BILATERALLY SYMMETRIC ANIMALS ARE
USUALLY POLARIZED, HAVING A HEAD AND TAIL REGION, AND ARE WELL ADAPTED FOR DIRECTIONAL
MOVEMENT
WHAT SHAPE ARE BACILLUS BACTERIA
ROD SHAPED
WHAT SHAPE ARE COCCUS BACTERIA
BALL SHAPED
WHAT SHAPE ARE SPIRILLUM BACTERIA
LONG SPIRAL SHAPED
WHAT DOES BLOOD CONSIST OF
,CELLS, CELL FRAGMENTS, AND FLUID CALLED PLASMA, WHICH IS YELLOW COLORED AND MAKES UP
ABOUT 55 PERCENT OF HUMAN BLOOD
WHAT DOES BLOOD PLASMA CONSIST OF
BLOOD PLASMA CONTAINS WATER AND ELECTROLYTES, PROTEINS, GLUCOSE, AND LIPIDS.
WHAT ARE THE MOST ABUNDANT CELLS IN BLOOD
RED BLOOD CELLS ARE THE MOST ABUNDENT CELLS IN THE BLOOD THEY ARE ALSO KNOWN AS
ERYTHROCYTES
WHAT IS WHITE BLOOD CELLS
ALSO KNOWN AS LEUKOCYTES. WHITE BLOOD CELLS HAVE NUCLEI AND DON'T CONTAIN HEMOGLOBIN
AND CAN LIVE FOR YEARS.
WHAT ARE CELL FRAGMENTS
PLATELETS, ALSO CALLED THROMBOCYTES
WHAT DO PLATELETS DO
PLATELETS HELP THE BLOOD CLOT TO STOP BLEEDING WOUNDS. PLATELETS ARE ATTRACTED TO A
WOUND ACTIVATE EACH OTHER AND STICK TO THE WALL OF THE BLOOD VESSEL TO FORM A PLATELET
PLUG
WHAT IS THE BALTIMORE CLASSIFICATION?
VIRUS CLASSIFICATION BASED ON NUCLEIC ACID GENOMES AND REPLICATION TYPE
, WHAT IS ARE BIODIVERSITY THREATS
HABITAT LOSS , INVASIVE SPECIES, OVER HARVESTING, AND CLIMATE CHANGE
WHAT IS HABITAT LOSS
: HABITATS CAN BE DEGRADED OR DESTROYED AS HUMANS CLEAR LANDSCAPES OR CHANGE LAND -
USE PATTERNS FOR DEVELOPMENTS HIGHWAYS CAN DIVIDE AND FRAGMENT HABITAT, KNOWN AS
HABITAT FRAGMENTATION. HABITAT FRAGMENTATION CAN LIMIT THE NATURAL RANGE OF
ORGANISMS AND CREATE ARTIFICIAL INTERACTIONS WITH HUMANS AND OTHER ORGINISMS ( DEER
HAVING TO CROSS HIGHWAYS )
WHAT ARE INVASIVE SPECIES?
ARE SPECIES THAT ARE NOT NATIVE TO A REGION ARE SAID TO BE NONNATIVE OR INVASIVE. NOT ALL
NONNATIVE SPECIES ARE INVASIVE. INVASIVE SPECIES CAN LEAD TO SIGNIFICANT ECONOMIC AND
ENVIRONMENTAL HARM, AND MANY INVASIVE SPECIES HAVE BEEN INTRODUCED TO AN AREA BY
HUMAN ACTIVITY.
WHAT IS OVER HARVESTING
OVERFISHING OF A SPECIFIC FISH SPECIES IS OVERHARVESTING.
WHAT IS CLIMATE CHANGE
CHANGES IN THE CLIMATE CAN HAVE PROFOUND EFFECTS ON ORGANISMS AND THREATEN
BIODIVERSITY IN A REGION.
WHAT ARE THE WORLDS BIOMS
TERRESTRIAL OR LAND, FRESHWATER BIOMES, AND MARINE BIOMES
