Unit 8 SOL Review: Classification (including viruses)

Match the following vocabulary terms wit their definitions

• Common Ancestor

• The original species before speciation occured

• Homologous Structure

• Body parts that do the same job, but are made of different stuff, do not indicate a common ancestor

• Taxonomy

• A chart scientists use to show speciation over time

• Analogous Structure

• Similar body parts made of the same stuff, does indicate a common ancestor

• Cladogram

• How scientists organize and categorize organisms

A long time ago, people believed in the ​ (a)   , which said that living things (like diseases) could come from non-living things. Several scientists, like Redi and Koch, did ​ (b)   which disproved this theory. Today, scientists follow the ​ (c)   , which says that diseases can be caused by ​ (d)   like bacteria and viruses. This theory has helped scientists develop new technologies, like ​ (e)   that can help protect people from disease.
