Microorganisms that are capable of causing disease are called pathogens. Although microorganisms that cause disease often receive the most attention, it is important to note that most microorganisms do not cause disease. In fact, many probably provide some protection against harmful microorganisms because they effectively compete with the harmful organisms for resources, preventing them from growing.

Answer: B) It controls the autonomic nervous system and regulates hunger and thirst sensations.
Answer:
Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.
Explanation:
Ribosome Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s
Cell wall Prokaryotes such as bacterial cell contain cell wall.Cell wall of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.
Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.
Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.
