What do archaea and bacteria have in common in terms of their biological characteristics and evolutionary history?
Archaea and bacteria are both single-celled microorganisms that lack a nucleus and other membrane-bound organelles. They are both prokaryotes, meaning their cells do not have a defined nucleus. In terms of evolutionary history, archaea and bacteria are believed to have diverged from a common ancestor billions of years ago, making them some of the oldest forms of life on Earth.

What is the difference between bacteria and archaea in terms of their genetic makeup and evolutionary history?
Bacteria and archaea are both types of single-celled microorganisms, but they differ in their genetic makeup and evolutionary history. Archaea have unique genetic characteristics that set them apart from bacteria, such as different cell membrane structures and genetic sequences. In terms of evolutionary history, archaea are believed to be more closely related to eukaryotes (organisms with complex cells) than to bacteria. This suggests that archaea and bacteria evolved separately and have distinct evolutionary paths.
Why are archaea more closely related to eukaryotes than bacteria?
Archaea are more closely related to eukaryotes than bacteria because they share similar genetic and molecular characteristics, such as the presence of introns in their genes and similar RNA polymerases. This suggests a closer evolutionary relationship between archaea and eukaryotes compared to bacteria.
What are the 2 domains of bacteria?
The two domains of bacteria are Bacteria and Archaea. These domains consist of different types of bacteria with distinct characteristics and evolutionary histories. Archaea are known for their ability to thrive in extreme environments, while Bacteria encompass a wider range of species found in various habitats.
Why are archaea in a different domain from bacteria?
They are thought to have separate paths of evolutionary development. They developed along different evolutionary paths. They had independent evolutionary development.

What were the monerans Why did systematics split them into two kingdoms?
Monerans were a group of single-celled organisms, including bacteria and archaea, that were classified under a single kingdom due to their prokaryotic characteristics. Systematics split them into two kingdoms—Bacteria and Archaea—based on significant differences in their genetic, biochemical, and structural properties. This division reflects their distinct evolutionary lineages and helps clarify their roles in ecosystems, as well as their responses to environmental changes. The separation allows for a more accurate understanding of biological diversity and evolutionary relationships.
Why are archaea in a different domain from bacteria?
They are thought to have separate paths of evolutionary development. They developed along different evolutionary paths. They had independent evolutionary development.
Which is not a kingdom in the eukarya domain?
Bacteria archaea
What are archaea not classified with?
Archaea are not classified with bacteria or eukaryotes, as they represent a distinct domain of life. Unlike bacteria, archaea have unique biochemical and genetic characteristics, such as the composition of their cell membranes and the structure of their ribosomal RNA. They are often found in extreme environments, but they can also inhabit more common habitats. This separation into their own domain reflects significant evolutionary differences.
What are the 6 major Kingdoms currently recognized?
The six major Kingdoms currently recognized are Animalia (animals), Plantae (plants), Fungi (fungi), Protista (protists), Archaea (archaea), and Bacteria (bacteria). These Kingdoms classify all living organisms into broad groups based on their characteristics and evolutionary relationships.
What are the 3 domains used to classify living things?
Bacteria, Archaea (prokaryotes), Eukarya (eukaryotes)
Why are archaea in a separate domain from bacteria?
Archaea are placed in a separate domain from bacteria due to significant genetic and biochemical differences. Archaea have unique cell membrane structures, distinct RNA polymerases, and different metabolic pathways compared to bacteria. These differences have led scientists to classify archaea in a separate domain called Archaea.
What differences caused scientists to classify bacteria and archaea into different domains instead of just diffrent kingdoms?
Scientists classify bacteria and archaea into different domains due to significant differences in their genetic, biochemical, and structural characteristics. Archaea possess unique membrane lipids and certain metabolic pathways that are distinct from those of bacteria. Additionally, their ribosomal RNA sequences show substantial divergence, indicating a separate evolutionary lineage. These fundamental differences justify their classification into separate domains, reflecting the evolutionary complexity of life.
Why are members of this domain called archaea?
Members of the domain Archaea are called archaea because they were initially mistaken for bacteria due to their small size and simple structure. When they were discovered to be a distinct group of organisms with unique characteristics, they were given the name Archaea, derived from the Greek word "archaios" meaning ancient, to reflect their ancient origins in evolutionary history.
