Homo sapien</p><p>S5.O2.d Relate the importance Read the following passage and answer the questions below. of classification systems to the development of The purpose of classification is to take information that might seem unrelated and put it together in a science useable system. This is important for many reasons. For example: You might know that the clownfish is knowledge. sensitive to metal medications and contamination. Knowing that maroon fish are also members of the same sub-family, should lead you to conclude that these species might share similar reactions to foods and diseases and they do! Knowing what species are related saves investigating every species separately. Organisms that are related to human beings are widely tested for medications rather than testing humans. Do we test the medications on snails? No, snails are widely separated from humans in classification. S5.O2.e Rats or pigs are much closer in body functions and structures and are more useful to see if a medication is safe Recognize that for humans. classification is a tool made by 13. How are classification systems useful? science to A. They help us find the cause for disease in fish. describe perceived B. They can help us investigate every species individually. patterns in C. They help us know what species are similar to each other. nature. D. They can help us discover the purposes of genetic traits.</p><p>14. Rats and pigs do not look much like humans. How is it possible that tests with pigs and rats could teach us about how a substance may respond to humans? A. As mammals they respond in similar ways to humans. B. As amphibians, they respond in similar ways to humans. C. As reptiles, they respond differently than humans. D. As four-legged animals we are all alike.</p><p>15. How has classification helped science knowledge advance? Classification… A. puts things in groups based on their environment. B. helps understand characteristics of different organisms C. shows how the atomic structure of matter is organized. D. provides a way to group organisms together by adaptations.</p><p>S5.O3.a 16.
