4. Which taxon is the broadest? __ 5. Which taxon is the most specific? __ 6. How many domains exist currently? __ 7. Why do we use a standardized naming system for all organisms? __

## Step1<br />The broadest taxon is the one that encompasses all other taxa. In the hierarchical system of biological classification, the broadest taxon is the domain.<br /><br />## Step2<br />The most specific taxon is the one that includes the fewest number of organisms. In the hierarchical system of biological classification, the most specific taxon is the species.<br /><br />## Step3<br />The number of domains is a fact that can be determined by looking at the current scientific consensus.<br /><br />## Step4<br />The reason we use a standardized naming system for all organisms is to ensure that each organism has a unique and universally accepted name. This is important for clear communication among scientists and for the organization of biological information.
