DOES NOT HAVE: CELL WALL, SMALL OR NO VACUOLES, NO CHLOROPLAST, LYSOSOMES ( WHICH CLEAN UP THE CELL)T EUKARYOTIC PLANT CELL INCLUDES: - Ans - 1.) CELL WALL, LARGE VACULOLE, CHLOROPLASTS, MITOCHONDRIAN, GOLGI APPARATUS, NUCLEUS, CYTOPLASM, RIBOSOMES, ROUGH AND SMOOTH ENDOPLASMIC RETICULUM. FERMENTATION USES SUGAR IN THE ABSENCE OF WHICH MOLECULE? - Ans - O FOUNDATIONAL SPECIES - Ans - a single species that creates the structure of the ecosystem, usually dominant to the area GENE POOL - Ans - DIFFERENT TYPES OF GENES IN A POPULATION GENETIC DRIFT - Ans - A change in the gene pool of a population due to chance GENETIC FLOW - Ans - movement of genes from one population to another GOLGI APPARATUS - Ans - modifies and packages proteins for export by the cell HOMOLOGOUS PAIRS OF CHROMOSOMES HAVE SEPARATED INTO TWO CELLS. SISTER CHROMATIDS IN EACH CELL HAVE NOT YET LINED UP IN THE

MIDDLE OF THE CELL. WHICH STAGE OF THE CELL CYCLE IS THIS? - Ans - PROPHASE II HOW IS DNA STRUCTURED DURING THE METAPHASE STAGE OF MITOSIS? - Ans - THE CENTROMERE AT THE CENTER KEEPS DNA LINED UP AT THE CELL'S EQUATOR IN THE HARSH ARTIC TUNDRA, THE SURVIVIAL OF ONE SPECIES IS OFTEN DEPENDENT ON THE ACTIONS OF ANOTHER. FOR EXAMPLE, THE ARTIC BUMBLEBEE POLLINATES THE ARTIC POPPY AND RECEIVES ENERGY NECTAR IN RETURN. WHICH INTERACTION IS OCCURING BETWEEN THESE SPECIES? - Ans - MUTUALISM IN THE HUMAN BODY, MUSCLE FIBERS METABOLIZE SUGARS TO PRODUCE ENERGY.

WHICH METABOLIC PROCESS DO FAST TWITCH MUSCLE FIBERS CARRY OUT? - Ans

  • FERMAMENTATION IN WHICH EUKARYOTIC ORGANELLE DOES PROTEIN SYNTHESIS OCCUR? - Ans - ENDOPLASMIC RETICULUM KEYSTONE SPECIES - Ans - INFLUENTIAL TO THE COMMUNITIES, BUT NOT ABUNDANT. HAS A STRONG EFFECT ON THE STABILITY OF COMMUNITY 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? - Ans - FASTER THAN AVERAGE SWIM SPEED MAIN COMPONENT OF CELL MEMBRANE IS: - Ans - PHOSPHOLIPIDS MALE PEACOCKS COMPETE WITH ONE ANOTHER TO MATE FEMALE PEACOCKS.

SISTER CHROMATIDS ARE BEING SEPARATED AND MOVING TOWARDS

OPPOSITE POLES OF THE CELL. WHAT STAGE OF MITOSIS IS THIS? - Ans - ANAPHASE SMOOTH ENDOPLASMIC RETICULUM - Ans - TRANSPORT LIPIDS AND HORMONES 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 GRADIENT).
