1Â Â Â Â Â Â Â Â Â Accordingto evolutionary theory, organisms with very similar phenotypes:
a.        are always veryclosely related
b.        always have verysimilar genotypes
c.        will evolveunder very similar conditions.
d.      can have very differentgenotypes.
e         both c andd are correct.
2Â Â Â Â Â Â Â Â Â Which ofthe following is NOT supported by scientific evidence?
a.     Probability Theory
b.     Evolutionary Theory
c.     Genetic Theory
d.     Cell Theory
e.     all of the above ARE scientifictheories supported by large amounts of evidence
3.        At the beginningof western settlement millions of buffalo lived on the GreatPlains. By 1890 only about 750 survived in the entire country. Thisis an example of:
a.        a severemutation
b.        negative geneflow
c.        the foundereffect
d.        a geneticbottleneck.
4.        Livestockproduction in the U.S. today uses nearly 3 times as manyantibiotics as are prescribed for all human patients. It is mostlikely that routine use of antibiotics in animal feed will resultin:
a.        an effective,long term way to eliminate disease-causing bacteria in the animalsand therefore increase food production.
b.        the animalsdeveloping resistance to the antibiotics.
c.        an increasednumber of antibiotic-resistant bacterial strains.
d.        the eliminationof viral infections and thus increased food production.
e.        ever fewerdisease-causing bacteria in the environment.
5.        Roaches are acommon indoor pest in the south. Why must people routinely changethe brand of insecticide (roach killer) they use?
a.        The activeingredients in the insecticide break down over time.
b.        Antibiotic-resistance genes in roach DNA are transferred touninfected roaches by contact with infected ones.
c.        The directaction of insecticides on roach DNA cause individual roaches toslowly become immune.
d.        Some individualroaches in the population may have a mutation providing somenatural immunity to the first insecticide and their offspring willbegin to predominate.
e         Changes inthe chemical formulation of insecticides constantly improve theireffectiveness.
6.        Both Darwin andWallace were greatly influenced by Thomas Malthus who observedthat
           a.        populationsincrease geometrically (exponentially).
           b.        populationsincrease at the same rate as the food supply.
           c.        populationsremain at their carrying capacity.
           d.        food supplyusually increases faster than the population that depends onit.
7.        Examples ofadaptive radiation of species would be easiest to find:
a.        near nuclearpower plants.
b.        in isolatedregions with many diverse habitats.
c.        on mountain topsexposed to higher UV radiation.
d.        in moist, humidtropical rainforests.
e.        in areas withmuch human contact.
8.        Gene flow is anevolutionary factor associated with:
a.        artificialselection
b.        randommating
c.        increasedmutations
d.        migration ofindividuals
e.        smallpopulations
9.        Evolution occursin:
a.        gametes.
b.        somaticcells.
c.        individuals.
d.        organelles.
e.        populations.
10.      English moths originallyhad a normal (bell-curve) distribution phenotypes. What was theresult of the smoke and soot from the industrial revolution onthose English moths?
a.        All phenotypesin the original population were reduced as the populationdeclined.
b.        Both extremes ofthe curve were selected against and the curve became narrow andtall.
c.        Heterozygoteindividuals were weaker and died off.
d.        The entirepopulation of moths became darker but retained the bell-shapedcurve.
e.        The mothpopulation went extinct.
