Some people consider Staphylococcus aureus to be a primary pathogen, while others classify it as an opportunist. Which of the following statements supports the opinion that it is an opportunist?

A. Outbreaks in groups of people such as football players have been reported.
B. Antibiotic-resistant strains of S. aureus are increasingly being reported.
C. S. aureus is found in the nasal passages of many healthy people.
D. Only some strains of S. aureus produce toxins.

C

Explanation:

Opportunist are organisms that are found naturally in other living organism and only cause disease in the organism when its immune system is compromised for example HIV virus lowers immune system strength by reducing the amount of the CD4⁺ cells available thereby exposing the organism to attack from opportunistic organism such Staphylococcus aureus. The opinion that supports the statement is S.aureus is found in the nasal passages of many healthy people.

answer; /// i really don't understand your question/statement.but/lions do fight over territory and breeding rights, sometimes to the death,this is called( i hope this answered your luck

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
