Name Chapter 17 Date examining samples of water and mud from 1 aUpon nearby river, you come across an unidentified organism. The organism is unicellular and autotrophic. In addition, you can identify a membrane-bound nucleus in the cells. To what kingdom does it belong? A Plantae B Fungi C Protista D Bacteria Use the following illustration to answer questions 2 and 3. Present I H K J G C E A 10 million years ago Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. type of diagram is shown in the 2 What illustration above? dichotomous key cladogram DNA profile pedigree and J in the illustration are close together. 3 IWhat does this indicate? A B C D The system of assigning two names to identify 4 an organism is called binomial nomenclature. What does the first name of an organism identify? A family B kingdom C species D genus The scientific name for the African elephant is 5 Loxodonta africana. What is the species name? A B C D Loxodonta africana L. africana Loxodonta sp. D F B A B C D Class They share few derived characters. They are closest to the common ancestor. They share many derived characters. They share the same derived characters as H and K. provides evidence that three distinctly 6 What different vegetables, such as broccoli, cauliflower, and kale, share a recent common ancestor? A They have cell walls. B They produce strong aromas when cooked. C They are about the same color. D They have nearly identical chromosomes. 7 Which taxa is equivalent to a phylum? A B C D domain family order division Why are euglenoids classified with plantlike 8 protists? A They form pseudopods. B They contain chloroplasts and undergo photosynthesis. C They have a nucleus surrounded by a membrane. D They have a flagellum. STANDARDIZED TEST PRACTICE CHAPTER 17 33 Chapter 17 Name Date model below allows scientists to compare 9 The DNA sequences from two species to estimate how long it has been since they diverged from a common ancestor. What is the name of this model? !NCESTRAL GENE 4IME 4WO MUTATIONS 4IME .EW MUTATIONS Class is the system by which each species is bm What given a two-part scientific name? A B C D phylogenetics cladistics taxonomy binomial nomenclature would be the least reliable evidence in bn Which determining whether or not two animals share a taxonomic relationship? A physical structures and appearance B appearance of their chromosomes C diet and nutrition D DNA sequences is a cluster of organisms distinct from bo Which other clusters that shows evidence of a pattern A B C D bk molecular clock cladogram pedigree family tree Members of which kingdom secrete enzymes into their food and then absorb the digested matter directly into their cells? A Protista B Fungi C Plantae D Animalia of ancestry and descent? A kingdom B division C phylum D species What statement describes the thinking of bp scientists before Darwin presented his theory of evolution? A All species that ever lived were still alive. B All species were separate and unchanging. C Species could be distinguished by their DNA. D Species could be distinguished by their color patterns. scientists began to learn more about bl As geologic time, they incorporated their findings into systems of classification. What is the system that takes into account an organism’s evolutionary history? A binomial nomenclature B phylogeny C taxonomy D historical classification 34 CHAPTER 17 STANDARDIZED TEST PRACTICE Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. 3PECIES
