The bacterium Staphylococcus aureus is commonly found in the nasal cavity of healthy people. If inhaled into the lungs, however,
it may cause pneumonia. Staphylococcus aureus is best described as___________ 1) transient microbiota.
2) a parasite.
3) a mutualist symbiotic partner.
4) resident microbiota.
5) both resident microbiota and opportunistic pathogen.
The correct answer is option 5) "both resident microbiota and opportunistic pathogen".
Explanation:
Resident microbiota are considered all the bacteria that is within the human body of healthy people. Since Staphylococcus aureus is found at the nasal cavity of healthy people is considered part of the resident microbiota. Staphylococcus aureus is also an opportunistic pathogen, because it takes advantage of an unusual opportunity to infect. This opportunity could be to be inhaled into the lungs, or that its host gets immunologically repressed.
The answer is seeds and pollen. They allow for the free dispersion of plants in terrestrial environments hence allowing plants colonize new habitats. Additionally, the seeds and pollen can remain dormant for a period of time and sprout only in favourable conditions for plant growth
The statement that best describes the work of these researchers is "As a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done." I hope my answer has come to your help. God bless and have a nice day ahead!
Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time. Soil scientists call these the factors of soil formation
