- Q1Some organisms have genes that improve their ability to survive and reproduce. If the genes also help their offspring survive and reproduce, then which of the following will most likely increase?The frequency of the genes in one individualThe number of genes in one chromosomeThe frequency of the genes in the populationThe number of genes in the species60sBIOL.7e
- Q2The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these most likely increases?Natural selectionReproductive mutationsGenetic variationEnvironmental fitness60sBIOL.7f
- Q3Zoogeographic regions are characterized by the presence of specific groups of animals. These regions are determined by the taxonomic or phylogenetic relationships of animals. The map shows the zoogeographic regions proposed by the naturalist Alfred Russel Wallace in 1876. The similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between the organisms in both locations?1 and 25 and 67 and 83 and 460sBIOL.7a
- Q4After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the following conclusions is supported by this information?Scorpions do not appear in their original state in the fossil recordScorpions living today have increased their numbers since they first appearedScorpions in the fossil record are smaller than their descendants areScorpions have changed as a result of natural selection60sBIOL.7b
- Q5A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown below. For the scarlet king snake, the adaptation of having a banding pattern like the eastern coral snake's is known as mimicry. The outcome of this adaptation in the scarlet king snake is to -make it easier for the scarlet king snake to attract preyallow the scarlet king snake to blend in with its environmentmake it easier for the scarlet king snake to interbreed with the other snakeprotect the scarlet king snake from predators60sBIOL.7e
- Q6The limbs of several organisms are shown in the illustrations below. Scientists sometimes compare the limbs of these organisms to look for evidence of common ancestry. These limbs provide evidence of common ancestry because they -have the same basic structureperform the same functionare parts of mammalsare the same size60sBIOL.7a
- Q7The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials. The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -belong to the same speciesmust range great distances to eatare descended from a common ancestorhave very similar skeletal structures60sBIOL.7a
- Q8The cladogram shows the evolution of land plants as indicated by fossil records.Which discovery would challenge the validity of this cladogram?A large aquatic vascular plant about 200 million years oldA fossil of a fern more than 425 million years oldA moss species that has existed for less than 380 million yearsA species of algae that has existed for less than one million years60sBIOL.7b
- Q9Lord Howe Island is a volcanic island in the Tasman Sea that is about 11 km long and 2.8 km wide. The island has two species of palm trees, Howea forsteriana and the more abundant Howea belmoreana. The two species do not interbreed even when they grow very close to each other. Which evolutionary process fails to occur?Genetic drift of Howea forsterianaGene flow between the two speciesMutations in Howea belmoreanaNatural selection of adaptive traits in both species60sBIOL.7f
- Q10Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1 mm long to 38 mm long and live in most environments. The diets of ants range from flowers and seeds to fluids from their own larvae. Ants have been able to successfully inhabit so many different environments because their populations have been able to -adapt to a variety of habitats and food sourceshybridize with other species of insectsoccupy habitats that have no other life-formsfill niches usually occupied by mammals60sBIOL.7e
- Q11In Madagascar scientists have discovered a moth, Xanthopan morganii praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid, Angraecum sesquipedale. The orchid has a nectar-producing tube that is 27.9 cm long. How is the moth's proboscis size an adaptation for its environment?The moth can pollinate other flowersThe moth has little competition for foodThe moth has time to feed during the dayThe moth can avoid larger animals60sBIOL.7e
- Q12Genome maps provide the DNA sequences of chromosomes. Some scientists have compared the genome maps of a hedgehog and a sloth. What do these genome maps allow the scientists to determine?The methods of protein synthesis that each species usesHow closely related the two species are to each otherThe color patterns of the offspring of each speciesHow much the size ranges of the two species differ60sBIOL.7a
- Q13Which condition is essential for natural selection to result in a new species?A static environmentA long life spanAn inherited variationUnlimited resources60sBIOL.7d
- Q14In the European roe deer (Capreolus capreolus), implantation of embryos after breeding is delayed. The deer breed in July or August but do not give birth until the following May or June. From summer to late December, the embryo rests in a state of dormancy as a 30-cell blastocyst. In late December or early January, the embryo sends a signal that causes the female to release hormones, allowing the embryo to continue to develop normally. Why is delayed implantation an advantageous adaptation for the European roe deer?Delayed implantation enables the female to give birth to more fawns each yearDelayed implantation allows the mother to continue to breed with other malesWithout delayed implantation, the females would not be able to carry a pregnancy to full termWithout delayed implantation, the fawns would be born in the winter when food is scarce and the weather is harsh.60sBIOL.7e
- Q15Two populations of mice living in the same forest are separated by a large water-filled ditch. After a rainstorm, flooding brings several mice from one population to the other population. When the mice from the first population reproduce with members of the second population, which of the following will likely occur?All the offspring will die as a result of reproductive mutationsThe offspring will be genetically identical to their parent from the first populationThe offspring in the second population will have greater genetic varietyThe offspring will be forced to leave the second population60sBIOL.7f
