In what way is the three-domain system of classification an improvement over the five-kingdom system? Choose 1 answer: A Plants are separated from animals. B Archaea are separated from bacteria. C Fungi are separated from plants. D Prokaryotes are separated from eukaryotes.

## Step 1<br />The three-domain system of classification is an improvement over the five-kingdom system because it provides a more accurate representation of the relationships among different types of organisms. The five-kingdom system, which includes Monera, Protista, Fungi, Plantae, and Animalia, groups all prokaryotic organisms (those without a nucleus) into a single kingdom, Monera. This grouping is not accurate because it lumps together organisms that are fundamentally different.<br /><br />## Step 2<br />The three-domain system, on the other hand, separates these prokaryotic organisms into two distinct domains: Bacteria and Archaea. This separation is based on the fact that these two groups of organisms have significant differences in their genetic makeup and metabolic processes.<br /><br />## Step 3<br />Therefore, the three-domain system provides a more accurate representation of the relationships among different types of organisms, making it an improvement over the five-kingdom system.
