why are bacteria and bacteriophages useful?
Homework Answers
Bacteria :
In Human health:
They are normal inhabitant of human intestine which mostly comprises human microbiota. Tehy help to digest our food , make vitamins for us (vit B12) . They protect our skin from invaders. Bacteria (E. coli ) recombinants make insulin and other antibiotics for humans.
In Food:
Bacteria are responsible for fermentation industry workings, dairy industry, tanning (leather) industry.
In Degrading our waste: They are major partner in sewage treatment plants.
Bacteriophages :
Phages are parasites of bacteria. They are used to control bacteria which dominates in a population. The recently used phage therapy uses phages to destroy harmful Salmonella , also called a salmonella phage therapy.

Lysogenic bacteriophages contribute to bacterial virulence because bacteriophages: Select one: a. produce toxins. O b. carry plasmids. c. kill human cells. O d. give new gene sequences to the host bacteria. e. kill the bacteria, causing release of endotoxins. HEPA filters are effective because they are designed to remove all airborne particulates, including microorganisms down to: Select one: a. 0.01 micrometers. b. 10 micrometers. c. 1 micrometer. O d. 0.3 micrometers. e. 10 nanometers.

Many bacteria reproduce asexually by binary fission and offspring inherit identical copies of parent genes. Why do bacteria also utilize transduction for replication within the cell? creation of bacteriophages transfer of genetic material into host increased rate of evolution environmental changes outside of cell
