The correct answer is - increased resource supply.
The resource extraction is a process though which the supply of resources on the market is achieved. In the past century, the extraction has been increasing constantly, thus the supply of resources on the market increased significantly because the demand for the same increased significantly.
On the other hand, the extraction of resources, very often, has very bad impact on the environment. The soils are destroyed, which is especially concerning considering the fact that fertile soils are desperately needed. The vegetation is cleared or polluted to a degree where it dies out, and the water also gets contaminated. Lot of this issues are extremely serious, and urgent measures have to be taken in order for such damage to be stopped.

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.
Answer:
DNA is a double stranded molecule that belongs to a group of larger molecules (macromolecules) called NUCLEIC ACIDS.
Nucleic acids are formed by joining together many smaller molecules called NUCLEOTIDES.
Nucleotides consist of:
- Pentose sugar (pentagon)
- Phosphate group (circle)
- Nitrogenous (rectangle)
Your answer would be A because none of the others make sense, Hope that helps!
