- Q1Having a standard taxonomic system benefits the scientific community by allowing scientists from all over the world to do which of the following?Have a common system for the classification of locations containing fossilsHave a common understanding in the classification of organismsUnderstand how other scientists classify predator-prey relationshipsUse a similar system to classify the impact of removing species from ecosystems60s
- Q2Some 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 number of genes in one chromosomeThe number of genes in the speciesThe frequency of the genes in one individualThe frequency of the genes in the population60s
- Q3The 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?Reproductive mutationsGenetic variationNatural selectionEnvironmental fitness60s
- Q4A student collected the animal shown below on a field trip. The student used a dichotomous key and a microscope to classify the animal. How should this animal be classified?PlatyhelminthesArthropodaMolluscaAnnelida120s
- Q5Zoogeographic 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?5 and 61 and 23 and 47 and 8120s
- Q6Arthropods are joint-legged animals. Spiders, crabs, pill bugs, centipedes, and millipedes are examples of the many types of arthropods. Which of these arthropods are most closely related?Arthropods of the same speciesArthropods of the same genusArthropods of the same familyArthropods of the same class60s
- Q7After 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 record.Scorpions living today have increased their numbers since they first appeared.Scorpions in the fossil record are smaller than their descendants are.Scorpions have changed as a result of natural selection.60s
- Q8A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown here. 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 interbreed with the other snakeprotect the scarlet king snake from predatorsmake it easier for the scarlet king snake to attract preyallow the scarlet king snake to blend in with its environment120s
- Q9The 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 structurperform the same functionare the same sizeare pars of mammals120s
- Q10The 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-have very similar skeletal structuresmust range great distances to eatare descended from a common ancestorbelong to the same species120s
- Q11The cladogram shows the evolution of land plants as indicated by fossil records. Which discovery would challenge the validity of this cladogram?A fossil of a fern more than 425 million years oldA large aquatic vascular plant about 200 million years oldA species of algae that has existed for less than one million yearsA moss species that has existed for less than 380 million years120s
- Q12Lord 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?Mutations in Howea belmoreanaGenetic drift of Howea forsterianaNatural selection of adaptive traits in both speciesGene flow between the two species60s
- Q13Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water. Based on the observations of the student, which organisms most likely belong to the taxonomic group for bacteria?Organisms 2 and 3Organisms 3 and 4Organisms 1 and 2Organisms 1 and 4120s
- Q14Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1 mm 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-fill niches usually occupied by mammalsoccupy habitats that have no other life-formshybridize with other species of insectsadapt to a variety of habitats and food sources60s
- Q15The Linnaean taxonomic system classifies organisms into divisions called taxa. If two organisms belong to the same taxonomic group, they are related. Similarity at which of these levels indicates the closest relationship?GenusOrderKingdomClass60s
