Organism in kingdoms archaebacteria live in environments that are very hot or very cold Which other characteristics is common to organisms in this kingdom

Archaebacteria belong to the kingdom 'Archaea'. They resemble bacteria when observed under a microscope.They are single-cell organisms. However,they differ from prokaryotes in many ways.

•They have a completely different cell membrane so that they can survive and thrive in harsh environments

•Unlike bacteria,their cell wall and membrane can be stiff and gives a specific shape such as flat,rod shaped or cubic.

•the absence of peptidoglycan in cell wall,instead contain lipid and protein to give them strength and resistance against chemical.

•The cell membrane of archae are made up of phospholipid bilayer but unlike bacteria and eukaryotes,the bilayers have ether bonds.These ether bonds have the ability to resist chemical and helps them to survive in very extreme environments that might otherwise kill them.

•They have multiple RNA polymerase that contain multiple polypeptide

•They have initiator tRNA with unmodified methionine(unlike bacteria).

•They have the ability to survive in very high temperatures,in acidic environment and alkaline environments and even have tolerance for high salt content.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
