Who developed the classification system, which we use today, for living things? A Aristotle B Carolus Linnaeus C Charles Darwin D Gregor Mendel (LS.5a) 13. Organisms are placed in a kingdom, based on all the following characteristics except: A whether or not the organism’s cells have a nucleus. B whether or not the organism is autotrophic. C whether or not the organism is multicellular. D whether or not the organism is colorful. Use the chart to answer questions 17 and 18. KINGDOM Characteristics Unicellular Multicellular Has nucleus Producer Consumer Monera Protista Fungi all none none some some most some all some some some most all none all (LS.5a) 14.

Use the description of the experiment and the results table below to answer the next two questions. A student performed an experiment in which five plants were placed in sand and five plants were placed in soil. All ten plants were the same type, given equal amounts of water, and exposed to equal amounts of sunlight. The experiment lasted for two weeks. The table below shows the growth of each of the plants. Plants In Soil 1 2 3 4 5 Increase in height Plants Increase in Height (in centimeters) in Sand (in centimeters) 2.0 1.9 2.2 2.1 1.9 1 2 3 4 5 0.5 0.6 0.4 0.7 0.6 (LS.1g) 25. The variables that remained the same were: A amount of sunlight. B amount of water. C type of plants. D All of these conditions remained the same. (LS.1g) 26.
