Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water. Based on the observations of the student, which organisms most likely belong to 

the taxonomic group for bacteria?

• Organisms 1 and 2.

• Organisms 3 and 4.

• Organisms 1 and 4.

• Organisms 2 and 3.

Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?

• In order to avoid confusion with the identification of organisms.

• Because Linnaeus established the system.

• So that Latin names can be applied for a practical purpose.

• In order to place organisms in different groups.
