More offspring are born than can actually survive All of the following statements would be consistent with Darwin’s view of natural selection EXCEPT More offspring are born than can actually survive Individuals with traits favorable for survival are more likely to survive and reproduce Traits are passed from parents to offspring Mutations most often result in favorable traits that lead to increased rates of survival Variations exist among members of the same species 1,100, p

Which of the following explains why bacteria such as staphlococcus aureus have become resistant to antibiotics? Throughout their lifetime, the bacteria become accustomed to the antibiotics The bacteria’s immune systems are able to adapt to and resist the antibiotics Some bacteria born with mutations are resistant to antibiotics, survive, and reproduce The bacteria become isolated from the antibiotics and are therefore unaffected by them 1,200

The bones of a human arm are homologous to structures in all of the following except a whale flipper butterfly wing bat wing bird wing frog forelimb 1,300, p

Mutation Genetic drift Migration Nonrandom mating Natural selection A species of brown algae is widespread in the Atlantic Ocean. It was recently determined that populations of this species living north of the Topic of Cancer have fewer genes encoding heat-shock proteins than populations of the same species living south of the Topic of Cancer. This difference is most likely the result of Mutation Genetic drift Migration Nonrandom mating Natural selection 1,400

Mitochondria and bacteria possess similar ribosomes and DNA. Which of the following best supports the statement that mitochondria are descendants of endosymbiotic bacteria-like cells? Mitochondria and bacteria possess similar ribosomes and DNA. Mitochondria and bacteria possess similar nuclei Glycolysis occurs in both mitochondria and bacteria. Both mitochondria and bacteria have microtubules. 1,500, p

There are frequent mutations There is no immigration or emmigration Hardy-Weinberg states that a population will maintain stable allelic frequencies if each of the following is true EXCEPT There are frequent mutations There is no immigration or emmigration There is random mating There is a large population size There is random reproductive success 2,100

A certain homozygous phenotype occurs in 16% of a specific population A certain homozygous phenotype occurs in 16% of a specific population. Assuming that all 5 Hardy-Weinberg criteria are met, what percentage of the population is heterozygous? 84% 58% 52% 48% 24% 2,200, p

The frequency of a certain recessive allele in a population is found to be 0.30. What percentage of the next generation would be expected to display the dominant phenotype? 91% 70% 49% 30% 9% 2,300, p

In a certain group of African people, 4 percent are born with sickle cell anemia. What percentage of the group has the selective advantage of being more resistant to malaria than those individuals who are homozygous for normal hemoglobin or for sickle cell anemia? 2% 4% 8% 16% 32% 2,400, p

800 moths 640 moths 320 moths 200 moths 40 moths A moth’s color is controlled by two alleles, G and g, at a single locus. G (gray) is dominated to g (white) . A large population of moths was studied and the frequency of the G allele in the population over time was documented, as shown in the figure below. If a sample of 1000 moths was taken in 1962, how many moths would be heterozygous? 800 moths 640 moths 320 moths 200 moths 40 moths 2,500

The condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as Sexual dependency Reproductive isolation Geographic isolation Adaptive radiation 3,100

Which of the following occurs due to geographic isolation? Allopatric speciation Non-random mating Genetic drift polyploidy 3,200, p

Lo siento, no entiendo, papi. The differences in crickets calls among sympatric species of crickets are examples of Hey baby, what’s up? habitat isolation temporal isolation physiological isolation behavioral isolation geographic isolation Lo siento, no entiendo, papi. Click Here! 3,300

If a selection pressure remove extreme phenotypes on either end of a phenotype gradient from the population, the type of selection occurring is Directional selection Disruptive selection Stabilizing selection Intrasexual selection Intersexual selection 3,400

Reduced hybrid fertility Reduced hybrid sterility Sometimes organisms from two different species mate and produce an offspring that does not survive to be of reproductive age. This is an example of Reduced hybrid fertility Reduced hybrid sterility Reduced hybrid viability Hybrid Breakdown Geographic isolation 3,500

The evolution of several species from a single species, each occupying a different niche Founder effect Kin selection Competitive exclusion Adaptive radiation Convergent evolution 4,100
