There’s actually 100 but only 8 of them infect humans
Usually, genes are transferred by bacteriophages, viruses that precisely takeover bacteria cells. Phages inject their own genetic material into the host cell like tiny syringes, compelling it to produce new phages. Throughout this occurrence, genes from the bacterial genome can be combined into the newly made phages. Subsequently, they inject their newly altered genetic load into other bacteria. By this, bacteriophages serve as a transportation, taking up DNA from one bacterium and leaving it into another. Bacteria can also connect through tiny connection tubes wherein they exchange pieces of DNA. They can take up genetic material from the environment as well. There are actually three ways for bacteria to transfer genes. The first one is called Conjugation, which is the transfer of DNA straight from one cell to another through cell-cell contact. Secondly, bacteria are adept at taking up DNA right from their environment and combining it into their genomes.This process is known as natural Transformation. Lastly, Transduction, wherein DNA is transferred from one cell to another by a virus.
The answer to this question is answer choices D
It is extremely labor intensive and costly. :-(
Answer:
Sea floor spreading
Explanation:
Sea floor spreading results in the formation of the oceanic basin.
After water has filled the basin, the sea floor begins to spread and move apart creating the ocean crust and its basins.
These are all due to different plate interactions within the earth.
After the crust has formed and filled with water, at divergent margins, new ocean floors are formed by volcanic activities at spreading centers.
The new crust is produced near the margin and subsequent ones push against it and away. The formation of new ocean floors product ocean basins.
