Answer:
The correct answer will be option A.
Explanation:
The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.
The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.
The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.
Thus, option A is the correct answer.
An example could be oil (olive, almond)

Sulfur dioxide and nitrogenous oxide released from industries and power plants infiltrate river ways by acidic rainfall. Sewerage and effluent are released into rivers in some regions. Pollution can decrease the pH of the water, attacking all organisms from algae to vertebrates. Biodiversity reduces with reducing pH.
Answer:
A system in dynamic equilibrium will have small changes that sum together to produce no net change. Dynamic equilibrium is different from a static equilibrium, in which the parts do not move once they've reached equilibrium.
