The human body has about 10 bacterial cells for every eukaryotic cell. Bacteria coat our skin, gut, and mouth. Also present are

protists, Archaeans, and viruses. Collectively, these organisms are our microbiota.The bacterial species Staphylococus aureus is found on the skin and in the nasal passages of about 20% of the human population. In healthy individuals, S. aureus is benign (does not cause harm) in these locations. However, if it is introduced into the bloodstream through, for example, a wound, it can make a person gravely ill. Thus, the ecological relationship of S. aureus with a human:
is always mutualistic.
Is always antagonistic.
can be mutualistic or antagonistic.
is fixed or unchanging.
is benign.

Answer:

can be mutualistic or antagonistic.

Explanation:

According to the given information, the bacterial species <em>Staphylococcus aureus </em>present in some nasal passages and on the skin do not harm the person. The ecological interaction wherein both organisms are benefited and none is harmed is known as mutualism. Here, <em>Staphylococcus aureus</em> does not cause any disease in human when present on the skin and in the nasal passage, that is both are in mutualism.

However, when present in the bloodstream, the same bacterial species can cause infections such as sepsis and represents antagonist effects on the host.  

Hence, the <em>staphylococcus aureus </em>species may be mutualistic or antagonistic to human.

Each of the proteins involved in DNA replication plays an important role. If one of these proteins was not functional it would h
Masteriza [31]

Answer:

Explanation:

1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..

2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.  

3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.  

4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.  

5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.  

6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
