Answer:
Transduction
Explanation:
Bacteriophages (or phages) are viruses known for its ability to contaminate and become a parasite in a bacteria. These phages can pass its DNA from a single bacterium to another bacterium, via a means referred to as genetic transduction.
This is believed to be the centre route through which bacteria evolve and possess the antibiotic resistance and virulence factors that increases the formation of new and an increasingly more pathogenic strains.
The mechanisms of genetic transduction includes generalized and specialized transduction.
The correct answer is: C) A large number of phages are released at a time
Lytic cycle of a bacteriophage is one of the two life cycles of viruses, other being lysogenic. Lytic cycle can be divided in stages:
• Attachment-viruses binds to the receptor on the surface of bacterial cell, usually it uses tail for the attachment
• Entrance-virus injects its genome material (DNA or RNA) into bacteria cell
• Replication and protein synthesis-virus uses mechanism of bacteria to replicate its genome and produce proteins. As a consequence, a huge number of new viruses are formed
• Lysis- viruses express protein for the bacterial lysis (bacterial cell expand and burst) and hundreds of new phages are released.

Acid rain is a combination of rain, snow, dust, and other particles with a ph lower than 5.6.
The acid rains occur when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and with the help of the winds and air currents that transport them. The sulfur dioxide and nitrogen oxides react with oxygen, water, and other chemicals, and they form sulfuric and nitric acids.
