The kingdom monera has been separated into two domains, the archaea and the bacteria. which of the following was most important in prompting scientists to change the way these organisms were classified? major differences were discovered in the structure and operation of the different species of monera. so many new species of monera were discovered that the kingdom got too large and needed to be separated. advances in technology revealed that some species of monera had nuclei and some did not. some species of monera were found that could live in colonies rather than as single cells.

The correct answer is the first statement.

Explanation:

The kingdom monera has been separated into 2 domains archaea and bacteria, because of differences in their structure and operation. Bacteria have simpler RNA polymerases than archaea. So, they sow similarities with eukarya in this matter.

Archaea do not posses peptidoglycan in their cell walls like bacteria. Archaea have distinct membrane lipid bonding from eukarya and bacteria.

Thus, the correct answer is the first statement.

organisms that are both used in toothpaste as well as cause malaria are protista and monera.

the answer is :
