Measurement Depth of Knowledge Level 2 7. Keys are used by biologists to accurately classify unknown organisms such as the unidentified female mosquito shown in the diagram below. These keys are designed to categorize organisms according to structural characteristics. The key shows various characteristics used to identify the difference between Anopheles, Deinocerites, Culex, Psorophoro and Aedes mosquitoes. From ExamGen 4.3 According to the key, which characteristic distinguishes a male from a female mosquito? A. Antennae appearance B. Palp length C. Leg scales D. Abdomen points 8. The Periodic Table of known elements is a tool used by chemists that exhibits many levels of organization. Use the periodic table to answer the following question. (From http://www.bpc.edu/mathscience/chemistry/history_of_the_periodic_table.html ) Electronegativity is a value that expresses the ability of an atom to pull electrons towards itself. A periodic pattern of electronegativity is expressed as follows: 1. Electronegativity increases as you go across the periodic table. 2. Electronegativity decreases as you go down the periodic table. Which of the following elements has the highest electronegativity? A. Sulfur (S) B. Chlorine (Cl) C. Selenium (Se) D. Bromine (Br) 3rd Item Specification: Explain that classification systems can be modified over time to account for new information. Depth of Knowledge Level 1 9. Classification tools, like the periodic table or binomial nomenclature, are A. generally accepted by all scientists who are experts. B. modified if necessary as new data and observations are collected. C. not modified once completed if based on careful experimentation. D. generally only accepted if scientists agree with collected data. 10. While conducting careful experimentation, a chemist discovered a new element. Chemists would A. ignore the new data because it did not fit into the generally accepted periodic table. B. create a new classification system with the new information. C. disagree on how to incorporate the new data and create many classification systems based on personal preference. D. modify the current periodic table to include the new data. Depth of Knowledge Level 2 11. The table provides a fictional scheme to classification of four Orders of animals. Use this fictional scheme to answer the following question. Order Food source Number limbs Teeth Reproduction Temperature regulation Outer layer A B C D Herbivore 4 Rounded Live birth Endotherm Carnivore 2 Sharp Eggs Endotherm Herbivore 2 Rounded Eggs Ectotherm Omnivore 0 None Live birth Ectotherm Hair Feathers Scales Scales A wildlife biologist discovers an animal that is an herbivore with four limbs, has sharp teeth, lays eggs, is endothermic, and has scales. Which order does this animal belong to? A. Order B because the animal has sharp teeth, lays eggs, and is endothermic. B. Order C because the animal is an herbivore, lays eggs, and has scales. C. A new order named B/C was created to better describe the new animal. D. A new order named C/D was created to better describe the new animal. 12. Dimitri Mendeleev proposed the following periodic table in 1869. This periodic table arranged the known elements (in 1869) by increasing atomic mass and then by physical properties. (From http://www.unit5.org/chemistry/christjs/Develop%20Periodic%20Table.htm) A chemist discovers an element with an atomic mass of 210. Which of the following proposes a likely placement into Mendeleev’s periodic table? A. Group III, Period 9 B. Group VII, Period 10 C. Group I, Period 12 D. Group VI, Period 11 Performance Benchmark N.12.A.6 Students know organizational schema can be used to represent and describe relationships of sets. E/S Answers to Sample Test Questions 1.
