Question

Which of the following characteristics can be related to Archaebacteria?
A All photosynthetic
B All fossils
C All halophiles
D Oldest living beings

Answer 1

Hint The ability of archaebacteria to survive in severe settings, such as those that are extremely salty, acidic, or hot. Archaebacteria have been shown to survive temperatures as high as 190° Fahrenheit, just 22 degrees below the boiling point of water, and acidities as high as 0.9 pH.

Complete step by step answer:
Archaebacteria are a collection of microorganisms that originated independently from bacteria and blue-green algae and are sometimes categorised as a kingdom.
Bacterial genetic and biochemical research quickly revealed that one class of prokaryotes differed significantly from "modern" bacteria, and indeed from all other modern life forms. These unusual cells were eventually given the name "archaebacteria" from the Greek word "archaea," which means "ancient." They are assumed to be modern offspring of a very ancient lineage of bacteria that originated around sulfur-rich deep sea vents.
Archaebacteria are prokaryotic organisms with only one cell. Halophiles, thermophiles, and methanogens are among them. Extreme habitats, such as regions with high salt concentrations, extremely high temperatures, and marshy areas, are where they can be found. They are bacteria that do not require sunlight to survive. They are the world's oldest living creatures. They are undeveloped organisms.

As a result, the right response is "Oldest living beings" , that is Option D.

Additional Information
Although archaebacteria have a single, spherical chromosome like bacteria, their gene transcription is similar to that of eukaryotic cells' nucleus.
As a result, the majority of genes involved in most life processes, such as cell membrane formation, are more closely shared by Eukarya and Bacteria.

Note: Ether-linked phospholipids are used in the cell membranes of archaebacteria, while ester-linked phospholipids are used in the cell membranes of bacteria and eukaryotes. The sugar used by archaebacteria is similar to, but not identical to, the peptidoglycan sugar found in bacteria cell membranes.
