Both bacteria and archaea have different Ribosomal RNAs (rRNA). Archea have three RNA polymerases like eukaryotes, but bacteria have only one. Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). These lipids in the membranes of archaea are unique and contain ether linkages between the glycerol backbones rather than ester linkages. Archaea resembles eukaryotes more than bacteria. Their ribosomes work more like eukaryotic ribosomes than bacterial ribosomes.
These two microorganisms also differ in genetic and biochemical ways. Only within the last couple of decades, archaea were recognized as a distinct domain of life. They are extremophiles, meaning they thrive in physically or geochemically extreme conditions. They have similar ecological roles as bacteria. Both of these organisms react to various antibiotics in a different way.

Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called <u>primary </u>tumors or ones that can move called <u>metastatic </u>tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.
Answer:
due to a possible microbial infection. It is associated with bacterial (most common) and fungal infections.
